Docks built to last
Marine-grade aluminum
Our 6000-series aluminum won’t pit or rust, the same alloy used in saltwater marine construction.
Hand-built in Naples
Built since 1979, with the parts you may need down the road still made in the same shop.
Welded, not bolted
Frames are welded rather than bolted, so nothing works loose over time.
Built in Naples for your shoreline
Great Northern Docks has hand-built docks since 1979, and our New Hampshire customers get the exact same dock our Maine customers do. We weld every frame in Naples, Maine and get it to your lake, where a trusted install team, ours or yours, sets it on your shoreline.
New Hampshire lakes test a dock the same way ours do: unpredictable weather, exposed shorelines, and deep, cold water.
New Hampshire lakes we work with often
We build docks for New Hampshire’s lakes region and beyond. A few we know well:
- Lake Winnipesaukee. The state’s largest lake, with deep water, big wind, and exposed shorelines that demand a serious dock.
- Squam Lake. Clear, protected in places and open in others, with rocky bottoms that often call for a floating configuration.
- Newfound Lake. Deep and cold, with the kind of clean water owners want to protect with a dock that lasts.
- Lake Sunapee and Winnisquam, along with the smaller lakes and ponds across the region.
Don’t see your lake? Tell us where you are. We’ve built for waters across New Hampshire and we know what these shorelines ask of a dock.
