Final Dive Co. brings dive crews to Bay Shore Marina, the Connetquot River clubs, and every private creek dock — handling hull inspections, dock assessments, and recovery on-site.
Our Bay Shore service area covers Great South Bay, Penataquit Creek, Awixa Creek, and Nicoll Bay — including Bay Shore Marina, Oakdale Yacht, and Vanderbilt Wharf Marina, and the waters off Bay Shore Yacht Club, Islip Yacht Club, and Connetquot River Yacht Club. Don't see your marina or dock? We travel the whole shoreline — call us and we'll come to you.
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++++.
Every body of water on Long Island dives differently. Here is what our crews plan for when we work Great South Bay, Watchogue Creek, Awixa Creek and the Fire Island ferry channels.
Shallow sand and silt bay bottom with soft mud through the creeks and marina basins. Dredged channels hold soft accumulated sediment between maintenance cycles.
Small tidal range typical of Great South Bay behind the barrier island. Current is modest through most of the Bay Shore waterfront, which makes for comfortable working conditions when the wind cooperates.
One to four feet, wind-dependent. The ferry channels see constant prop wash from Fire Island traffic through the season, which keeps the bottom stirred during operating hours.
Heavy. Warm shallow bay water plus sheltered marina basins produces fast accumulation. Boats here often need mid-season attention rather than a single annual cleaning.
Bay Shore's heavy seasonal traffic means running gear takes abuse. Prop, shaft and outdrive inspection catches strike damage and line wraps that owners often do not know about until performance falls off.
It depends on your bottom paint and how much you run, but Great South Bay is a fast-fouling environment. Many owners here get better results from a mid-season cleaning plus an end-of-season inspection than from a single annual service.
Yes. Props, shafts, struts, rudders and outdrives are all inspected in the water. We photograph what we find and give you a documented report so you can decide whether a haul-out is actually warranted.
Yes, with appropriate surface marking and traffic awareness. The ferry channels are active and we plan operations accordingly.
