dock types

3 Lakes Docking builds and installs docks of all types for waterfront homes on New Hampshire’s Newfound Lake and Squam Lake. The 3 Lakes Docking team will help you choose the dock type that works best for your shoreline location.

Crank-up Docks

Crank-up docks (also known as lift-up docks) feature a sturdy aluminum truss design that allows for the dock frame to be “cranked up,” once the decking has been removed.

Many crank-up docks are straight, but depending on your shoreline, there may be opportunities for an L-, T-, or U-shaped system.

Crank-up docks are "cranked up" and out of the water during the cold winter months.

Pipe Docks

Pipe docks (also known as stationary docks) do not move with the water level. They feature aluminum pipes that rest on the lake/pond bottom and wood, aluminum, or composite decking.

Pipe docks are highly customizable and can be configured in various shapes, including straight, L-shaped, T-shaped, and U-shaped.

Pipe docks must be removed during the winter months.

Floating Docks

Floating docks are designed for lakes and ponds that experience fluctuations in water depth and that have soft or muddy bottoms.

Floating docks feature platform-style decking that sits atop airtight drums. Typically, floating docks are square or rectangular in shape and are anchored into the body of water.

Floating docks do not need to be removed during the winter months though the decking can be.

Decking Materials

3 Lakes Docking offers a variety of decking choices, including wood, permeable PVC, and composite materials.

When choosing a decking material, there are a few important things to consider:

  • how will you use the dock;
  • what “look” is attractive to you;
  • how much maintenance are you willing to do; and
  • how long do you expect the decking to last?

Each material has its benefits; ultimately, it’s a balance between your preferences and your budget.

Thru Flow decking example


ThruFlow is a popular choice for docks as it requires virtually no maintenance and will not rot, decay, splinter, or warp. There are many options to customize the decking, from colors and finishes to textures and surfaces.

Composite decking example


Composite decking options, like Trex and AZEK, are a lower-maintenance alternative to wood decking. Though it doesn’t need to be sealed or stained like wood decking, composite decking should be kept clean and washed regularly to avoid mold or mildew growth.

Wood decking example


Hardwoods, such as cedar, contain natural substances that tend to resist rot, decay, and insects. Wood decking requires regular maintenance, including washing annually and sealing or staining every few years.
