Serving Port Jefferson, NY

LOCAL DIVE CREWS, ON YOUR WATER

Port Jefferson Harbor is a deepwater hub for boaters across the mid-North Shore, from the transient slips at Danfords to the moorings off the village dock. Final Dive Co. dive crews work Port Jeff Harbor, Setauket Harbor, and Conscience Bay — handling hull inspections, dock and piling assessments, and item recovery on-site, so you never lose a day to a haul-out.

Where We Work in Port Jefferson

Our Port Jefferson service area covers Port Jefferson Harbor, Setauket Harbor, Conscience Bay, and Long Island Sound — including Danfords Hotel & Marina, Port Jefferson Marina, and Setauket Harbor Marina, and the waters off Port Jefferson Yacht Club.

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++++.
