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++++.

Working Conditions in Freeport

WHAT WE ACTUALLY FIND DOWN THERE

Every body of water on Long Island dives differently. Here is what our crews plan for when we work South Oyster Bay, Jones Inlet, the Freeport canals and Middle Bay.

Bottom Conditions

Shallow sand and silt with soft mud through the canal system and dredged basins. Jones Inlet is high-energy shifting sand.

Tide & Current

South Oyster Bay behind the barrier island runs a modest tidal range, but Jones Inlet moves serious water and the canals see real flow on the tide stages. Inlet-adjacent work is current-scheduled.

Visibility

One to four feet, degrading quickly with wind and after storms. The dense canal system holds turbidity longer than open bay because there is less flushing.

Fouling Pressure

Heavy. Freeport's canal system is warm, sheltered and slow-moving, which is close to ideal growing conditions. Boats kept in the canals foul faster than boats on open bay moorings.

The Freeport Detail That Matters Most

Freeport's bulkheaded canal network is aging infrastructure sitting in a tidal environment. Bulkhead toe scour and tieback condition are the recurring findings, and both are invisible from the property side.

Common Questions

FREEPORT DIVE SERVICES, ANSWERED

How do I know if my canal bulkhead is failing?

Usually you cannot tell from above. The early signs are below the waterline: erosion at the toe, loss of backfill through failing sheeting joints, and corrosion at the tieback connections. By the time you see settlement or leaning from the yard, the underwater problem is well advanced. That is what an underwater bulkhead inspection is for.

Do you work throughout the Freeport canals?

Yes. We work the full canal network, the Nautical Mile waterfront and the South Oyster Bay and Middle Bay shoreline, including private residential bulkheads and docks.

Can you dive near Jones Inlet?

We work the inlet approaches with operations timed to the current. Jones Inlet moves a lot of water and we plan around the tide rather than fighting it.
