Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts across Pine Island, Florida, in unincorporated Lee County. Pine Island is the largest island on Florida's Gulf Coast and the only one in the area with no bridge to the open Gulf — boats reach open water by way of Pine Island Sound, Matlacha Pass, or Charlotte Harbor. Much of the surrounding water is shallow flats, which makes local knowledge of depth and access as important as the construction itself.
Marine construction services on Pine Island
Crocker Marine is a full-service marine contractor — docks, seawalls, boat lifts, dredging, and inspections, in-house. See the full range of services or browse completed projects across Southwest Florida.
Docks
Pine Island Sound and Matlacha Pass frontage is shallow and flat in most places, so dock length and access channel matter more here than on a deep canal. We build new docks and handle repair, replacement, accessories, and canopies and shade covers.
Seawalls
Not every Pine Island property is seawalled — mangrove shoreline is common — but where a wall exists, concrete and vinyl seawalls age the same as anywhere on the Gulf Coast. We install and replace both and keep sound walls going with repair and maintenance before a replacement or new wall.
Boat lifts
We install and service boat lifts from Coastal Boat Lifts in Fort Myers, sized for the island's typically shallow flats. Repair covers cables, motors, bunks, and controls.
Dredging
Access channels and canal ends around Pine Island shoal easily given how shallow the surrounding sound and pass already run. Our residential dredging restores permitted depth, permitting handled.
Marine inspections
Our marine inspections give buyers, sellers, and insurers a written condition report on the dock, seawall, and lift.
Permits and local conditions on Pine Island
Marine construction on Pine Island is permitted through Lee County, since the island is unincorporated, along with the Florida Department of Environmental Protection and U.S. Army Corps of Engineers for work below the mean high-water line.
- No bridge to the open Gulf. Pine Island is the largest unbridged-to-the-Gulf island on this coast — boats reach open water through Pine Island Sound, Matlacha Pass, or Charlotte Harbor.
- Shallow water. Much of the surrounding sound and pass is flats country; depth at mean low water drives dock length and lift placement.
- Mangrove shoreline. A lot of the island's waterfront is natural mangrove rather than seawalled, and any work near it involves separate state review.
- Manatee zones. Slow-speed protections cover much of the surrounding water.

Pine Island marine construction FAQ
How do boats get from Pine Island to the open Gulf?
Through Pine Island Sound, Matlacha Pass, or Charlotte Harbor — there's no bridge or direct pass on the island itself. Route and depth both factor into dock and lift planning.
Who permits dock and seawall work on Pine Island?
Lee County, since the island is unincorporated, plus FDEP and the Army Corps for in-water work.
Does every Pine Island property need a seawall?
No — a lot of the shoreline is natural mangrove. We assess each site to see whether a seawall makes sense or another shoreline approach is better.
How shallow is the water around Pine Island?
Very, in many spots. We check depth at mean low water before designing any dock or lift, and dredging is often part of the project.
