The shop behind the water.
From one-off brackets to a full fabrication shop
Swim Platforms LHC LLC started small: a Lake Havasu City shop cutting and welding aluminum for boat owners who could not find parts that actually fit their hulls. Word travelled the way it does on the lake, one platform at a time, and the shop grew into the area's go-to name for custom swim platforms and SeaDek installs.
Everything we sell is designed, machined, welded, powder coated and test-fitted in house. Nothing is drop-shipped and nothing leaves the floor until it has been on a boat. That is also how the Sandbar Shade Company product line was born: a customer wanted shade at the sandbar, and the crew machined a mount that could take chop, wake and wind.

One crew, the full product line
