Fixed Dock vs Floating Dock: How to Choose the Best Option

Docks are an essential accessory for boat lovers who care about the safety of their vessels. Since water is rarely stationary, the constant wave action can cause damage.

When you decide to install a dock, you have to consider which type best suits your needs and location. Typically, there are two types – fixed dock vs floating dock. While they both serve the same purpose, they have significant differences. Here are some things to consider when choosing the best option.

What Is a Fixed Dock and How It Works

A fixed dock is usually anchored on the seabed using pilings. The decking is built from steel, wood, composite, or PVC. Since they are permanent fixtures, most fixed docks tend to be huge and can support heavier loads than floating docks.

Most importantly, fixed docks are more stable, and regardless of tide movements, they remain static.  As such, they have the propensity to weather massive storms.

What Is a Floating Dock and How It Works

A floating dock is a buoyant boat docking platform often made from plastic. Wondering how to put a floating dock in the water? They are usually attached to the shore to create a dry berth. The docks utilize the upward force created by water tides as they rise and fall.

Typically, a floating dock exerts a less downward force on the water than the buoyancy pressure beneath it. This mechanism explains why they stay afloat even when supporting significant loads on them. Typically, a floating dock requires about 70% buoyancy to remain afloat.

What to Consider When Choosing between Fixed vs Floating Dock

Investment Budget

Both types of docks have different price points, but the exact fixed or floating dock cost depends on the materials used for construction. Typically, fixed docks take more construction efforts, and the supporting pilings must be anchored deep into the seabed to secure firm support for the decking. This calls for superior expertise and materials since you need to hire professionals to drill the auger into the seabed.

On the other hand, floating docks are prefabricated by the manufacturer and often don’t require complex workmanship. How much is a floating dock? It depends. Some floating dock kits include all the necessary hardware to set up the platform independently.

Longevity and Maintenance

Fixed docks tend to last longer than floating decks. And that’s because floating docks are constantly submerged in water, thus accelerating the wear and tear. Typically, the effects are more pronounced in salty waters.

Usually, fixed docks can last for about 25-35 years, while a floating deck lasts for 25-30 years. However, proper dock maintenance routines can improve the lifespan of your boating platform.

Water Bodies and Space

If you live in locations with an expansive waterfront, you may want to consider a fixed dock. These docks can be huge and often suitable for areas with prominent shorelines. Also, if the area experiences lots of traffic, it can affect your floating dock. Consistent wakes can cause more wear and tear on the mounting hardware than a fixed dock.

If the water is shallow, a floating dock might start rubbing the sea bed during low tide, thus increasing the chances of damaging the dock floats. When the water body is too deep, a fixed dock becomes too expensive to install. This requires long support piping, which does not only come with prohibitive costs but might also warp after some time.

Therefore, a fixed dock is ideal for shallow water bodies with massive traffic, while floating docks are best suited for areas where deep water is close to the shore.

Noise

Fixed and floating decks have different installation methods. Typically, floating docks consist of hinged hardware to make them float and swing with the tide to avoid structural stress on the parts.

Since some of the parts are fabricated from heavy-duty steel, they can get noisy during strong tides in rough waters.  And once the steel starts to rust, the noise can only increase. On the other hand, fixed docks don’t have moving parts, therefore, are quiet.

Conclusion

Regardless of whether you want to build a new dock or replace it, it’s best to choose an option depending on your circumstances. And since there are pros and cons of fixed and floating dock, the most important thing is to ensure you’re working with a contractor who values quality.
