Serving Shelter Island, NY

LOCAL DIVE CREWS, ON YOUR WATER

Ringed by protected harbors, Shelter Island is a boater's island — Coecles, Dering, and West Neck each holding their own fleet. Final Dive Co. brings dive crews to Coecles Harbor Marina, the Shelter Island Yacht Yard, and Dering Harbor for hull inspection, mooring service, and recovery, all without leaving the water.

Where We Work in Shelter Island

Our Shelter Island service area covers Shelter Island Sound, Coecles Harbor, Dering Harbor, and West Neck Harbor — including Coecles Harbor Marina & Boatyard, Shelter Island Yacht Yard, and Piccozzi's Dering Harbor Marina, and the waters off Shelter Island Yacht Club. Don't see your marina or dock? We travel the whole shoreline — call us and we'll come to you.

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++++.
