Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts on Boca Grande, Florida, on Gasparilla Island in Lee County. Boca Grande faces Gasparilla Sound and Charlotte Harbor on one side and the Gulf of Mexico on the other, next to Boca Grande Pass — one of the deepest natural passes on the Gulf Coast and famous for its tarpon fishing. The island's historic district and its access by a single toll causeway both shape how marine construction happens here.

Docks
Sound-side docks on Boca Grande benefit from unusually deep water close to shore near the pass; Gulf-front sites take real wave exposure. We build new docks and handle repair, replacement, accessories, and canopies and shade covers.
Seawalls
Boca Grande's waterfront homes carry concrete and vinyl seawalls that face more direct Gulf and harbor exposure than an inland canal wall. 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 deeper water many Boca Grande properties enjoy near the pass. Repair covers cables, motors, bunks, and controls.
Dredging
Even with the pass's natural depth, some canal and marina slips on the island shoal. Our residential dredging restores permitted depth, permitting handled.
Marine inspections
Given the values on Boca Grande, our marine inspections give buyers, sellers, and insurers a written condition report on the dock, seawall, and lift.
Permits and local conditions on Boca Grande
Boca Grande is unincorporated, so marine-construction permits go through Lee County, along with the Florida Department of Environmental Protection and U.S. Army Corps of Engineers for work below the mean high-water line. Much of the village sits within the Boca Grande Historic District, which adds design review for exterior and waterfront work.
- Historic district review. The Boca Grande Historic District (National Register) affects how docks and other waterfront structures are reviewed for design compatibility.
- Deep water near the pass. Boca Grande Pass is one of the deepest natural inlets on the Gulf Coast, which gives many sound-side properties unusually good boat access.
- Gulf exposure. Gulf-front seawalls and docks face open-water wave energy that inland canal structures don't.
- Island access. The island is reached by a single toll causeway, which is a factor in scheduling material delivery and equipment access.

Boca Grande marine construction FAQ
Does the historic district affect dock design on Boca Grande?
It can — the Boca Grande Historic District adds design review in much of the village. We confirm what applies before designing.
Who permits dock and seawall work on Boca Grande?
Lee County, since Boca Grande is unincorporated, plus FDEP and the Army Corps for in-water work.
Is the water really deeper near Boca Grande Pass?
Yes — the pass is one of the deepest natural inlets on this coast, which gives many nearby properties better boat access than a typical canal community.
How does Gulf exposure affect a seawall on Boca Grande?
Gulf-front walls take direct wave energy that inland canal walls don't, so design and material choice account for it. Request a free estimate or call (239) 841-9674.
