When planning a floating dock, one of the first decisions you’ll face is choosing the right kind of flotation. You want something affordable, durable, and able to support your dock and whatever you plan on putting on it—whether it’s people, kayaks, a pontoon boat, a canoe dock, or something bigger. That’s why so many find themselves weighing whether dock floats vs. plastic barrels make more sense for their waterfront property.

So are dock floats worth the price, or are 55-gallon plastic drum barrels a good way to save money on your dock project? Let’s find out.

Dock Floats: The Pros and Cons

When talking about dock floats for this comparison, we mean the professionally-built dock floats. When does it make sense to invest in dock floats, and when might you look for other solutions?

Advantages of Dock Floats

Dock floats come in various shapes, sizes, and materials to support different weights and applications, with capacities ranging from 450 to over 4,000 lbs per float. The most popular type uses closed-cell expanded polystyrene (EPS) foam inside a durable polyethylene shell. This means they’re incredibly buoyant, can withstand harsh weather and rough handling, and will never become waterlogged and sink your floating dock.

In addition, they offer advantages that aren’t possible with barrels:

  • Environmentally Friendly: Made with recyclable materials and free from harmful chemicals, you can rest easy knowing they won’t pollute the waterways.
  • Uniformity: All floats are identical in size and shape, so you can be sure your dock will be stable and sit evenly at water level. This makes for easy installation and eliminates the headaches of uneven weight distribution.
  • Aesthetics: Let’s be honest, appearance matters. Dock floats create a clean, professional-looking dock that enhances your waterfront property.
  • Durability: Dock floats are made from robust materials that withstand harsh marine environments. They resist punctures, UV degradation, and chemical damage, ensuring a long lifespan.
  • Ease of Installation: Many dock floats come with pre-drilled mounting holes and hardware, making them easy to attach to dock frames. This simplifies the installation process and saves time.

Disadvantages of Dock Floats

Their biggest disadvantage? The price tag. They cost considerably more upfront compared to other DIY solutions. However, the upfront investment pays off in the end. Also, depending on the location of your floating dock, sourcing specific types or sizes of dock floats might be challenging, potentially causing delays in your project.

Plastic Barrels For Floating Docks

If the cost of commercially available dock floats has you rethinking your plans for your floating dock, you might be considering 55-gallon plastic drums instead. While they make sense in some situations, using barrels involves important considerations to determine if this budget-friendly solution is right for you.

A plastic barrel, particularly a 55-gallon drum, is an alternative buoyancy solution for floating docks. These barrels are typically made from polyethylene and are repurposed from industrial or commercial use. They offer a cost-effective option for achieving buoyancy. However, they come with their own set of challenges.

Advantages of Using 55-Gallon Drums

The most attractive feature? The affordability. Used plastic drums are even cheaper. Some sources estimate you can cut your costs in half compared to commercial dock floats.

  • Cost: One of the most significant advantages of using 55-gallon drums is their low investment. They are often available for a fraction of the price of commercial dock floats, making them an attractive option for budget-conscious builders.
  • Availability: Plastic barrels are widely available and can often be sourced locally. This can expedite the procurement process and allow for quicker project completion.
  • DIY-Friendly: For those who enjoy do-it-yourself projects, using barrels can be a fun and rewarding experience. They offer a level of customization and creativity that commercial floats may not.

Plastic barrels can be tempting, especially if you’re working with a limited budget for a floating dock build.

Disadvantages of Using Plastic Drums

But are the savings of plastic barrels worth the potential drawbacks? Using 55-gallon drums requires careful planning:

  • Sourcing Challenges: Unlike commercially manufactured dock floats, which you can readily order from dealers, tracking down affordable, used plastic barrels in good condition takes time, effort, and networking. Depending on your location and the time of year, you may need to expand your search radius, potentially adding significant travel expenses.
  • Unknown History and Potential Contamination: You don’t always know the history of used barrels. Be wary of barrels that contain chemicals or hazardous materials, which may leach into the water over time. While thorough cleaning might help, the risks associated with contamination and its environmental impact can be a major concern.
  • Lack of Uniformity and Stability: Unlike manufactured floats with standardized sizes, drums can vary significantly, making installation more complex and requiring adjustments to keep your dock level stable.
  • Susceptibility to Damage and Leaks: Over time, plastic barrels can crack, puncture, or rust, leading to leaks and reduced buoyancy. Repairing damaged barrels is ongoing, potentially costing you more in the long run.
  • Limited Lifespan and Increased Maintenance: Barrels simply don’t have the same lifespan as purpose-built dock floats. They are not specifically designed for marine use. Over time, they can be prone to UV degradation, punctures, and leaks, requiring more frequent repairs or replacements, leading to more work and costs down the line.
  • Aesthetics: While beauty is in the eye of the beholder, a dock supported by mismatched barrels won’t have the same visual appeal as one using purpose-made floats.
  • Installation Challenges: Barrels can be bulky and may not integrate as seamlessly into dock designs. They can pose practical challenges during installation, such as ensuring they are securely attached and evenly spaced.

Comparing Dock Floats and Plastic Barrels For Floating Dock Construction

When choosing between dock floats and plastic barrels, consider the following factors. If cost is a primary concern, plastic barrels offer a more affordable option. However, if you have the budget, dock floats provide superior durability and ease of installation. They’re designed for long-term marine use and require less maintenance than plastic barrels, which may need more frequent checks and repairs.

Dock floats typically offer a more polished and professional look, while plastic barrels may look more utilitarian. If aesthetics are important to you, dock floats are the way to go.

For DIY enthusiasts, those who simply can’t make the investment or don’t mind doing lots of maintenance, plastic barrels provide access to greater customization and creativity in design.

One other thing to consider: project scale and complexity. For larger, more complex docks, the uniformity and reliability of dock floats may be advantageous.

At Carolina Waterworks, Inc., we’ve supplied numerous water and boat enthusiasts with the right supplies to build premium boat docks over the years. Keep reading to get our guidance on that crucial floatation calculation!

Calculating Dock Float Requirements

What goes into determining the magic number of dock floats for your project? It’s not just about the dock size, although that’s definitely a significant component.

Think about the weight of your decking materials, any permanently attached equipment or accessories you plan to add, and even the foot traffic you think your dock will get.

You will also want to consider usage type and environmental conditions. What are you using your dock for? Recreational activities? Heavy-duty commercial use? Also, a high-wave area vs. a calm freshwater lake, for example, demands a more robust dock float. 

It’s a good idea to overestimate your needs to get the weight you need your dock to support.

Understanding Dead Load and Live Load

What exactly is dead load? In simple terms, it’s the weight of the dock structure itself, including the decking, framing, and any permanent fixtures like benches or cleats. This weight remains constant and doesn’t change based on how the dock is used.

Live load, on the other hand, refers to the weight of anything that’s not permanently attached to the dock, like people, furniture, or equipment. This load can vary depending on how many people are on the dock and what they’re doing.

To figure out exactly how much flotation you’ll need, you’ll want to calculate the dead load of your dock based on the materials you’re using.

That means taking into account the dead weight of your decking, framing, and any permanent fixtures like benches or cleats.

Estimating Live Load for Your Dock

Estimating the live load is a bit trickier, as it depends on how you plan to use your dock. A good rule of thumb is allowing 30-50 pounds per square foot of live load, depending on the intended use.

For example, a residential dock mainly used for lounging and fishing might only need a 30-pound per square foot live load estimate. But if you plan on hosting large gatherings or using heavy-duty equipment on your swim dock, you’ll want to bump that estimate up to 50 pounds per square foot.

What is Buoyant Force?

In simple terms, buoyant force is the upward force exerted by water on an object that’s partially or fully submerged. For your dock to float, the buoyant force provided by the boat dock floats needs to be equal to or greater than the total weight or load of the dock.

The buoyant force is determined by the volume of water displaced by the dock floats, which is why choosing the right size and number of floats is essential.

Step-by-Step Dock Float Calculation

Alright, it’s time to put all this information together and figure out exactly how many dock floats you need to build a dock that’s safe, stable, and ready for all your waterfront adventures. We’ve got a simplified dock float calculation process you can use to figure out what you need!

Here’s a simple step-by-step guide to calculating the number and quantity of dock floats you’ll need:

  1. Calculate the total square footage of your dock. (Length x width = square footage)
  2. Multiply the square footage by 35lbs to get the total load. This estimate combines both the dead load and an average live load for typical residential dock usage.
  3. Divide the total load by the lift capacity of the dock float model you are using.

Example Calculation for a Specific Dock Size

Let’s walk through an example calculation for a 10′ x 12′ dock with composite decking. We assume a live load estimate of 40 lbs per square foot and a 470 lb lift capacity.

  • Total square footage: 10′ x 12′ = 120 sq ft
  • Total load = 120 sq ft x 35 lbs = 4,200 lbs
  • 4,200 lbs / 470 lbs= 9 floats

And there you have it!

Dock Float Options

After determining your flotation needs, the next step is to determine what type of dock float is best for your environment.

Air-Filled vs. Foam-Filled Dock Floats

The two main types of dock floats are air-filled and foam-filled.

If you decide you only need to replace part of your dock, extend it, or add more stability, air-filled dock floats will do the trick. They’re generally lighter than foam-filled, so they offer flexibility in installation for projects like extending an existing dock. They also tend to be cost-effective.

If you are building an entirely new structure, you’ll likely want to start with foam-filled floats. They may be slightly more of an investment upfront, but they are sturdier.

Selecting the ideal dock floats for your waterfront involves considering a variety of key factors designed to ensure durability, safety, and suitability to your specific needs, including:

  • Location and climate: Extreme weather requires more durable and resilient foam-filled dock floats for harsh conditions
  • Water conditions: Air-filled dock floats work best for calm freshwater, whereas foam-filled floats shine in rougher saltwater due to their robustness and better puncture resistance.
  • Dock usage: Foam-filled floats, with higher buoyancy and stability, are ideal for docks expected to support heavy loads or high foot traffic, whether for personal recreation or commercial operations.

When it comes to accessing your boat dock, you’ve got two main options: a ramp vs. a gangway. But which one is right for you?

Ramps and gangways each have unique pros and cons depending on your specific situation. As an industry leader in marine products, Carolina Waterworks, Inc. we carry both residential and commercial dock ramps and gangways. Check out this comprehensive overview to help you decide whether you need a dock ramp, gangway, or both!

Ramp vs. Gangway: What’s the Difference?

Ramps and gangways have some similar functions but different advantages, which can help narrow down what product you ultimately use for your dock.

How do you choose between a ramp and a gangway for your boat dock? Here are a few factors to consider when trying to decide:

  • Distance from shore to dock
  • Water conditions (calm vs rough)
  • Water level fluctuation
  • Accessibility needs
  • Budget
  • Dock type and size

Let’s get into the key differences between ramps and gangways.

Ramps for Boat Docks

A ramp is essentially a sloped surface that connects two levels–the shore and the dock–and is suitable for complex terrain. It allows you to easily walk, roll, or cart gear from land to water. Ramps typically attach to the dock with hinges or brackets, which allow them to adjust to changing water levels. Some ramps also have transition plates or rollers to create a smooth transition.

Marine-grade aluminum is the most popular choice for boat dock ramps. It’s lightweight, durable, and corrosion-resistant to protect against the harsh outdoor and marine elements. Plus, aluminum ramps are easy to install and adjust as needed.

Wooden ramps are a classic choice, but they require extensive maintenance if you plan to use them all year round.

Benefits of Using Ramps

There are plenty of perks to using a ramp for your boat dock. Ramps are:

  • Affordable
  • Easy to install and maintain
  • Ideal for short distances
  • Adjustable for changing water levels
  • Provides a smooth transition from land to dock

A ramp is an excellent choice if you have a relatively stable shoreline and water level. It’s a simple, cost-effective way to get from land to water. Ramps are great for connecting steep shorelines and banks to your floating dock or gangway. They provide easy access and a seamless transition from land to water. They’re also easy to install and maintain.

Drawbacks of Using Ramps

Here’s where ramps face some challenges:

  • Not suitable for rough water
  • Can be slippery when wet
  • May not be long enough for steep inclines
  • Require regular maintenance (especially wooden ramps)

If you’re dealing with choppy water, big waves, or drastic water level changes, a ramp might not be the best fit. They’re also not ideal for long distances; if you need easier access to span more than a few feet, a gangway might be a better choice.

Gangways for Boat Docks

A gangway is essentially a portable bridge that connects your dock to the shore. It’s typically longer and narrower than a ramp, with handrails on either side for safety.

Gangways are hinged at the dock end, which allows them to pivot up and down with changing water levels. The shore end may rest on a bulkhead, seawall, or pier, or it may be suspended above the ground.

To use a gangway, you simply walk across like you would a bridge. The railings and handrails provide stability and support, especially in wet or windy conditions.

Aluminum residential and commercial gangways are strong and weather-resistant.

Just like ramps, wooden gangways offer a classic look but require more upkeep. Steel gangways are incredibly durable but heavy and prone to corrosion.

Benefits of Using Gangways

Gangways offer a number of benefits:

  • Suitable for longer distances
  • More stable in rough water
  • Handrails for added safety
  • Easy to adjust in changing water levels

If you have to deal with choppy water, a gangway is an intelligent choice. The handrails are also a major plus for accessibility and safety; they are perfect for longer distances and floating docks. Plus, gangways come with handrails for added user safety. They’re a nice choice for public or commercial docks where accessibility is key.

Drawbacks of Using Gangways

Of course, gangways have their downsides too:

  • Bigger investment than ramps, both in terms of cost and installation
  • Require more space on the dock
  • Can be difficult to install and remove
  • May require a permit or variance

Choosing Between a Ramp and Gangway for Your Boat Dock

So, when considering a ramp vs. gangway, which makes the most sense for your particular water environment? Let’s weigh your options.

Distances and Water Conditions

As discussed, ramps are best for short distances and relatively stable water levels. They’re also more affordable and easier to install than gangways.

Gangways, on the other hand, are ideal for longer spans and rougher water conditions. They provide a safer, more stable walking surface and are easier to adjust for changing water levels.

Water Level Fluctuation

One of the biggest factors to consider when choosing between a ramp and a gangway is water level fluctuation. If your water levels change drastically throughout the year, a gangway is probably a better choice.

Gangways are designed to pivot up and down with changing water levels to maintain a safe, stable walking surface even as the water rises and falls. Conversely, ramps are more rigid structures and may become submerged or exposed as water levels change.

Dock Type and Size

Another important consideration is the type and size of your dock. If you have a small, narrow dock, a ramp may be better than a gangway.

Ramps are typically wider than gangways, so they can take up less space on your dock. They’re also easier to install and remove, which can be a plus if you need to store your dock in the off-season.

If you have a larger dock or a floating dock, a gangway may be a better choice. Gangways are designed to attach to floating docks and can more easily adjust to changing water levels than ramps.

Budget and Cost

Of course, budget is always a factor when it comes to boat dock accessories. Ramps are generally more affordable than gangways, both in terms of materials and installation.

However, it’s essential to consider the long-term costs as well. A high-quality gangway may cost more upfront, but it can save you money on maintenance and repairs over time.

Ultimately, the best choice for your budget will depend on your specific needs and priorities. Don’t be afraid to invest in quality materials and construction – your boat dock is a long-term investment, and it pays to do it right the first time.

Look for quality materials like marine-grade aluminum, slip-resistant decking options, and durable, weather-resistant finishes. A little extra upfront cost will save you big in the long run.

Ease of Installation and Maintenance

Finally, consider the ease of installation and maintenance when choosing between a ramp and a gangway. Ramps are generally easier to install than gangways, especially if you’re handy with tools.

However, gangways may be easier to maintain over time. Because they’re designed to adjust to changing water levels, they’re less likely to become damaged or submerged than ramps.

No matter which option you pick, be sure to follow the manufacturer’s instructions for installation and maintenance. A little TLC goes a long way when it comes to keeping your boat dock safe and functional for years to come.

Happy boating!

Floating docks are safe, easy to install, and have a longer lifespan than wood decks, making them an excellent choice for dock construction. When building your dock, you’ll need it to endure a demanding marine environment, withstand extreme temperature changes, and resist deterioration and UV rays.

The dock floats you choose are vital to your dock’s basic foundation; they should boost its structural integrity. The two main dock float designs are foam-filled and air-filled. While both types have pros and cons, let’s weigh foam-filled dock floats vs. air-filled options to determine which one is better for your dock project.

When Should I Use Air-Filled Dock Floats?

If you only need to replace part of your dock, extend it, or add more stability, air-filled dock floats will do the trick. They’re generally more lightweight than foam-filled to deliver flexibility on installation for a project like extending an existing dock. They also tend to be cost-effective.

Advantages of Air-filled Dock Floats

  • They’re lightweight: Air-filled dock floats are typically lighter than foam-filled floats, making them convenient to handle during installation and maintenance.
  • Ease of buoyancy control: Air-filled floats can be adjusted for buoyancy by adding or releasing air, allowing for some level of customization to accommodate varying loads or water conditions.
  • They’re budget-friendly: Generally, air-filled dock floats tend to be less expensive than foam-filled floats, making them a more budget-friendly option for some applications.
  • Minor repairs are straightforward: If damaged, air-filled floats can often be repaired relatively easily by patching small holes or leaks.

Disadvantages of Air-filled Dock Floats

  • Vulnerability to punctures: Air-filled floats are susceptible to punctures from sharp objects or impacts, leading to deflation and compromised buoyancy.
  • Less stability: Air-filled floats may provide less stability compared to foam-filled floats, especially in rough water conditions, as they can be more prone to tipping or rocking.
  • More maintenance requirements: Air-filled floats may require more frequent maintenance to ensure they remain properly inflated and functional over time.

When Should I Use Foam-Filled Dock Floats?

If you are building an entirely new structure, you’ll likely want to start with foam-filled floats.

Polyurethane, a closed-cell foam used for flotation, is strong, water-resistant, puncture-resilient, and doesn’t leach chemicals. While air-filled dock floats are lighter and cost less than foam, with air-filled components, you’ll need to ensure that what you’re buying stands the test of time and the impact of the elements.

Carolina Waterworks, Inc. is proud to offer top-of-the-line installed dock floats made of a thick-walled rotationally molded polyethylene shell that encapsulates expanded polystyrene. The thick polyethylene shell is impact-resistant and will also resist damage from marine life. The thick-walled plastic float case is packed with EPS (Empire Foam Solutions brand foam that is environmentally approved and exceeds all new government regulations. 

Our dock floats have maximum lift capacity for the waterfront, boaters, and marinas.

Advantages of Foam-Filled Dock Floats:

  • Durability: Foam-filled dock floats are generally more durable and resistant to punctures than air-filled floats, as they do not rely on air for buoyancy.
  • Ease of assembly: Foam-filled floats are easy to construct and transition from land to water.
  • Stability: Foam-filled floats often provide better stability, particularly in rough water conditions, as they have a more solid construction that helps to minimize rocking or tipping.
  • Low maintenance: Foam-filled floats typically require minimal maintenance since there is no need to monitor or adjust air levels.
  • Greater longevity: Foam-filled floats can have a longer lifespan compared to air-filled floats, as they are less susceptible to degradation from exposure to sunlight or fluctuating temperatures.

Cons of Foam-Filled

  • Heavier weight: Foam-filled dock floats are generally heavier than air-filled floats, making them more challenging to transport and install.
  • Limited buoyancy adjustment: Unlike air-filled floats, foam-filled floats do not offer the flexibility to adjust buoyancy levels according to specific requirements.
  • Higher initial investment: Foam-filled dock floats are often more expensive than air-filled floats, which may deter some budget-conscious buyers.

Comparing Foam Filled and Air Filled Dock Floats

If you have an existing structure to which you need to add buoyancy, consider adding air-filled floats to your current dock.

However, while they cost a little more, foam-filled dock floats are a better long-term investment in building an unsinkable dock with a sturdy, long-lasting base. They’re easy to assemble, UV and damage-resistant, and eco-friendly with no harmful chemicals.

Which Dock Float is Right for Me?

Selecting the ideal dock floats for your waterfront involves considering a variety of key factors to ensure durability, safety, and suitability to your specific needs, including:

  • Location and climate: extreme weather requires more durable and resilient foam-filled dock floats for harsh conditions
  • Water conditions: air-filled dock floats work best for calm freshwater, whereas foam-filled floats shine in rougher saltwater due to their robustness and better puncture resistance.
  • Dock usage: foam-filled floats, with higher buoyancy and stability, are ideal for docks expected to support heavy loads or high foot traffic, whether for personal recreation or commercial operations.

Floating docks are flexible, highly configurable, and lightweight. Compared to fixed docks, they are often less expensive and easier to construct, with fewer red tape hassles.

However, that convenience often comes with an important “But…” Floating docks are less stable than their fixed cousins. Floating docks can drift from their desired location and can be washed away in a storm. Even when they stay put, waves can toss them around, stressing and weakening the dock’s structure.

Adding stability becomes critically important to your dock’s safe use and longevity. Today, Carolina Waterworks presents six common ways to stabilize your floating dock.

1. Stabilize your Floating Dock with Weights

Introducing extra weight to your floating dock will enhance its stability. Attach weights – typically concrete or metal – along the length of your dock platform with chains or cables and lower them into the water. Determining the amount of weight required – often hundreds of pounds – and ensuring even weight distribution is key to optimal stability. Too little weight will be ineffective, too much weight could drag your dock below the surface, and uneven distribution could cause your dock to tilt or lean.

In other words, there’s some math involved. Suspending weights safely and effectively may be beyond the skill level of the typical DIYer. Not to worry – your Carolina Waterworks consultant is here to help!            

2. Stabilize your Floating Dock with Pilings

Another common dock stabilizing method is the use of pilings. Pilings are metal or wooden anchoring posts that are forced deep into the lake, river, or seabed.

Pilings then attach loosely to the floating dock platform. One popular attachment method employs horizontal hoops that slip over the piling posts and then bolt to the dock. The loose fit allows the dock to rise and fall with the water level while allowing very little side-to-side movement.

To reiterate, stabilizing your floating dock with pilings may be the best bet when your water levels rise and fall considerably.

3. Stabilize your Floating Dock by Attaching it to the Shore

Anchoring your floating dock to the shore is another reliable method of preventing your dock from drifting out of position or washing away. Two common materials used in this application are metal pillars and wooden posts.

To prevent rot, wooden piling posts, often made of southern yellow pine, must be treated for use in your local water conditions, whether your floating dock is in fresh, brackish, or salt water.

Similarly, metal poles and pillars should be constructed of heavy-duty, non-rusting metal to prevent corrosion. Zinc-coated galvanized steel has been determined best for freshwater docks, while saltwater docks perform best with stainless steel. Keep these requirements in mind for all your metal dock accessories such as fasteners, hinges, and cleats.

Follow these guidelines, and you can enjoy your floating dock for many seasons of safety, ease of use, and reliability!

4. Stabilize your Floating Dock by Adding a Gangway

There are times that your floating dock must be situated at a certain distance from the shore, to meet various depth requirements. In these instances, a gangway can help stabilize your floating dock.

A gangway is a type of ramp that extends from the shore to the dock. Gangways, typically constructed of sturdy metal or wood, often include handrails to provide extra balance and safety for you and your guests. A gangway brings additional benefits, including a reliable attachment to the shore and extra weight to help stabilize your floating dock.

5. Add a Roof for Extra Weight

Another method of introducing extra weight for added stability is to erect a roof over your floating dock. This may be particularly useful if your water is too deep for suspended weights to be effective.

Floating docks typically employ two styles of roof: the Gable roof and the Hip roof. Very basically, the Gable roof features two angled side planes that meet at a peak, with open ends. The Hip roof features four angled planes – two sides and two ends – with no opening. Generally, Gable roofs are less expensive, but Hip roofs offer a more refined look, better protection from the elements, and more of the stabilizing weight you are seeking.

Adding a roof to your dock is typically more expensive compared to suspended weights and other options. However, a well-constructed, attractive roof can add appeal and value to your deck and your property. Consider it an investment!  

6. Simplify with a Floating Dock Stabilizer Kit

At this point, you may be overwhelmed by your floating dock stabilization options. You may be wishing for an all-inclusive kit to simplify the process. Carolina Waterworks is happy to oblige! Our floating dock stabilizer contains all the components and accessories you will need to successfully complete this very DIY-friendly process, including:

  • An auger that twists into the sea, lake, or riverbed and acts at the feet of your metal pilings.
  • Brackets attach the floating dock platform to the metal piling.
  • Connectors join two lengths or sections of the floating dock.
  • Fasteners are the various nuts, bolts, pins, and washers you will need.
  • Metal pilings, typically non-corrosive steel

Of course, there are several stabilizer kit options based on your specific floating dock, as well as other considerations such as:

  • Climate and Typical Weather: from winter wind chill to hurricane season
  • Dock size, weight, and configuration
  • Local Codes and Regulations: the time to deal with red tape is BEFORE you begin construction!
  • Users: just you and your spouse? Or the whole clan with boats and jet skis?
  • Water Depth: you may have more options available when water is shallower.
  • Water Fluctuation: know your extremes and choose a method that accounts for both.
  • Currents and Wave Strength: Stronger waves require sturdier anchorage.

These components and accessories, along with our expert dock installation advice, are all you will need to successfully complete what is often a very DIY-friendly process.

Stabilize your Floating Dock with Carolina Waterworks!

Stabilizing your floating dock is a key step that will help keep your dock safe and useful for many years to come. Whether you choose to stabilize your floating dock with pilings or gangways, by adding weight or attaching a roof, or by tethering it to the shore, you are sure to have questions. How much stabilization is enough? What do my local conditions demand? How much will it cost, and how much of it can I do by myself? To answer these and other floating dock stabilization questions, look to your reliable resource: Carolina Waterworks. Contact us today!

Which is the better choice – a floating dock or a stationary dock? Carolina Waterworks believes that only YOU have the answer, based on your individual boating needs and environment. To find that answer, and to make a smart buying decision, it is helpful to consider the features of each dock style and see how they align with your priorities. Carolina Waterworks is here to help!

Floating Dock or Stationary Dock: An Introduction

Boat docks, made of various materials such as aluminum, wood, or composites, are placed along banks or shores to help boaters and swimmers make the transition from water to land, and vice versa.

Docks are constructed in two modes: floating and stationary. Stationary docks rest on vertical pilings driven into the lake, river, or ocean floor. Floating docks are buoyed by airtight cubes or drums below the decking, called dock floats. Floating docks are held in place by lines or cables that connect the dock to the shore or the floor or bed of the body of water.

Boaters must choose between constructing a floating dock or a stationary dock on their property. Boating professionals, enthusiasts, and your neighbors along the lake will all offer their opinions, but the decision should be based on your real-world considerations, such as the following.

Consider Your Location: Depth and Traffic

Is your body of water shallow or deep? Or does it fluctuate between the two? A stationary dock can be installed to meet shallow or deep conditions. Water that is too deep can present a problem, however, in that the pilings required begin to get pricey in terms of materials and labor. Water of fluctuating depth can also bring challenges for a stationary dock. When the water level drops, a stationary dock can necessitate a longer climb for boaters and swimmers. When the water rises your dock may be submerged, which results in muddy cleanup and potential damage to any electrical components.

High, low, or in between, a floating dock will adjust with the changing water level. This offers convenient and consistent ingress and egress for the boater and swimmer. However, if the water level drops low enough, the weight of your floating dock could cause stress on your floats if they contact the lake or riverbed. Water that rises too high may cause excess tension on the lines securing your floating dock in place.

Finally, consider the boating traffic. How busy is your waterway? More boats mean more wake, even if they obey the speed limit. The floating dock may pitch and rock, while the stationary dock will barely feel the effect. The same caution also applies in the case of storms and other bad weather.

In short, you may find that a stationary deck is better suited to shallower and more consistent water levels and is less affected by boating traffic. A floating deck may be better for deeper or fluctuating water levels with lighter traffic.

Installation, Maintenance, and Cost

In deeper water, a floating dock could be the less costly option because you will forgo the expense of installing pilings in favor of buoyant dock floats. However, dock floats carry their own costs. Deck size (square footage), materials used, and your expected load will determine the size and number of floats you must purchase for optimum safety.

A stationary dock requires the installation of pilings. These can be costly (especially the deeper you go), typically require professional installation, and sometimes entail environmental red tape due to their more permanent nature.

Another advantage of a floating dock is that installation and maintenance can be much more DIY-friendly than the stationary dock. On the other hand, a stationary dock can last longer with fewer maintenance issues. In fact, some estimates place the lifespan of a floating dock at around 20-30 years, while a stationary dock may last 25-35 years.

Floating Dock or Stationary Dock: Lifestyle Considerations

Finally, think about the ways you and your family interact with the water. Are you a retired couple mainly interested in fishing or an easy circuit around the lake? Or will your dock be full of kids and grandkids, swimming and riding jet skis? Will your boat be in the water all season, or will you haul it out from time to time?

Some less experienced boaters, or people with balance issues, can find it difficult to ingress and egress from a bobbing boat to a bobbing floating dock, and vice versa. As noted previously, a low water level can make your stationary dock harder to reach for younger and older swimmers. As for putting in and hauling out boats and toys, many boaters prefer to drive their craft up onto a boat lift. Most stationary docks can accommodate the addition of a boat lift, while some floating docks cannot.

Are you considering adding a dock to your property, but aren’t sure if a floating dock or stationary dock is the way to go? Begin by making an honest assessment of your location, your budget, and your boating lifestyle. Figure out how a dock will fit your family, not the other way around. Then take your questions and concerns to a qualified dock professional.

Carolina Waterworks, Inc. (CWi) fabricates and sells sturdy, low-maintenance, and eye-catching mooring buoys and marker buoys. Available in assorted sizes and configurations, our buoys are always on the job, making boating and dock life safer and easier! Please take a look at our buoy product offering.

Mooring Buoys by Carolina Waterworks

family of carolina waterworks buoys

Our mooring buoys are built to last! Their impact-resistant high-density polyethylene shells are 3/16” thick and they are filled with expanded polystyrene foam for the most reliable flotation.

Our standard buoy comes in white and is highlighted with a reflective blue strip. You can also order additional colors, graphics, reflective tape, and ballasts. Every sturdy, reliable buoy carries a two-year warranty.

Wear-resistant Polyethylene Construction

Another important feature that is unique to our line of mooring buoys is the thick, wear-resistant polyethylene tube that is molded directly into the shell of each buoy. Contrast this with competitors who often utilize loosely attached PVC pipe.

Reliable and Low-maintenance Mooring Buoys

A frequent problem that contributes to excessive buoy maintenance is algae growth which can degrade ground tackle. One considerable benefit of Carolina Waterworks’ polyethylene construction is that poly resists marine growth much better than PVC, so our buoy line can help extend the life of your ground tackle.                          

No-Scrape Mooring

buoys with shackle pockets

Exposed tackle on a buoy can lead to hull damage (and angry Skippers!), so CWi mooring buoys are available with an optional rope nest or shackle pocket feature that keeps the exposed metal away from your finish.     

Marker Buoys by Carolina Waterworks

Let them know with a durable, attention-getting marker buoy from Carolina Waterworks. With superior flotation courtesy of our high-grade expandable polystyrene foam and the rock-steady reliability of twenty pounds of ballast concrete, your Carolina Waterworks marker buoys are always on the job.

Ramps from Carolina Waterworks come in various widths and lengths for your convenience whether it is for commercial or residential use.

Ramp Surface Options from Carolina Waterworks

Our ramps are also available in various surface options, including:       

Ramps with Aluminum Decking:

More durable than wood, and at a fraction of the weight of steel, aluminum-deck ramps define long-lasting convenience. Installation and maintenance are quick and easy, as is removal at the end of the season – or when nasty weather threatens.

Ramps with Ipe Decking:

Forget all your fears about wood decking because Ipe (EE-pay) is the tropical king of wood density and hardness! This exotic hardwood species grows tall and strong in the forests of South and Central America. And with its rich coloring and fine to medium texture, Ipe is not just tough and durable (and naturally slip-resistant), but it is also easy on the eye!

Ramps with Poly Decking:

Carolina Waterworks ramps with poly decking are extremely durable and will resist the effects of sun and wear, such as rotting, molding, splitting, twisting, warping, and drooping. Its synthetic non-porous construction is extremely water-resistant. And it will stand up to the kinds of abuse boaters will throw at it, including food stains, chlorine, alcohol, and tanning lotion.

Ramps with Composite Decking

Carolina Waterworks ramps with composite decking will maintain their color without continual repainting and sealing. They maintain their structural integrity without warping or splintering. In addition, because the contents of composite decking consist partly of recycled plastic materials, it earns high marks for sustainability.
