Whether your vessel sits at Huntington Whaling Station Marina, Halesite Marina, or a private dock along Huntington Harbor, Final Dive Co. delivers professional underwater inspection and service without ever pulling your boat from the water.
Our Huntington service area covers Huntington Harbor, Huntington Bay, Lloyd Harbor, and Long Island Sound — including Huntington Whaling Station Marina, Halesite Marina, Mill Dam Marina, and Knutson Marine, and the waters off Huntington Yacht Club, Lloyd Harbor Yacht Club, and Masthead Cove 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 Huntington Harbor, Lloyd Harbor, Northport Bay and the open Sound.
A glacial harbor bottom: firm sand and cobble on the outer edges giving way to deep soft mud in the inner harbor basins, with scattered boulders left by the terminal moraine.
Huntington sits in the western Sound, where the tidal range is among the largest on Long Island. That vertical swing exposes and re-submerges the upper third of most pilings twice a day, which is exactly the band where wood rot and steel section loss show up first.
Visibility in the inner harbor is commonly two to five feet and drops after a hard rain when runoff pushes down the creeks. Outer Lloyd Harbor and the Sound edge clear up noticeably on a flooding tide.
Soft fouling starts in late May. By August, hulls left on a mooring through the season carry a mature growth layer plus hard growth on running gear and raw water intakes.
Ice pressure on inner-harbor pilings is a real seasonal risk here. Spring inspections routinely turn up shifted pilings and torn dock hardware from winter ice movement in the back of the harbor.
Yes. Every inspection we run in Huntington is done in the water at your mooring or slip. We photograph and document the hull, running gear, shafts, struts, rudders and intakes without the boat ever coming out. For most owners that turns a scheduled haul-out into a diagnostic decision rather than an automatic expense.
Huntington Harbor mooring fields run from shallow inner-harbor ground into deeper water toward Lloyd Harbor and the Sound. We work the full range. Depth changes our approach and bottom time, not whether we can do the job.
Yes. We inspect bulkheads, seawalls, revetments and pilings anywhere along the Huntington and Lloyd Neck shoreline, including toe scour below the visible waterline, which is where most bulkhead failures actually begin.
