Serving Sag Harbor, NY

LOCAL DIVE CREWS, ON YOUR WATER

Sag Harbor's deepwater village marina draws yachts from across the East End and beyond. For vessels berthed at the Sag Harbor Village Marina, Waterlink Marina, or the Sag Harbor Yacht Club, Final Dive Co. provides professional dockside underwater services — hull inspections, running-gear checks, and recovery — without the wait or expense of hauling out at a South Fork yard.

Where We Work in Sag Harbor

Our Sag Harbor service area covers Sag Harbor Bay, Shelter Island Sound, and Peconic Bay — including Sag Harbor Village Marina & Town Dock, Waterlink Marina, and Sag Harbor Launch & Moorings, and the waters off Sag Harbor Yacht Club. Don't see your marina or dock? We travel the whole shoreline — call us and we'll come to you.

Client Reviews

TRUSTED ON THE WATER

★★★★★

Avoided an expensive haul-out thanks to Final Dive Co. They inspected my 45ft yacht's hull, swim platform, and anchor system in one visit. Clean report and great advice. These guys go where others won't.

We have a private dock and finally found a team we had an excellent experience working with. They provided specialized underwater labor.

After last winter's ice damage I called Final Dive Co for a seawall and piling inspection. Same-day response, clear plan, saved me from bigger problems. A++++.
