Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts in Nokomis, Florida, in Sarasota County. Nokomis waterfront centers on Dona Bay and Lyons Bay, connected to the Intracoastal Waterway near Casey Key by the historic Blackburn Point swing bridge. The bays here run shallow, and the swing bridge is a real factor for anyone with a taller vessel.
Marine construction services in Nokomis
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
Dona Bay and Lyons Bay frontage is shallow, so dock length and access depth matter as much as the structure. We build new docks and handle repair, replacement, accessories, and canopies and shade covers.
Seawalls
Nokomis bay-front seawalls carry a mix of concrete and vinyl. 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 shallow bay depth. Repair covers cables, motors, bunks, and controls.
Dredging
Dona Bay and Lyons Bay shoal easily given how shallow they 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 in Nokomis
Marine construction in Nokomis is permitted through Sarasota County, since the community 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.
- The Blackburn Point swing bridge. This historic bridge to Casey Key limits vessel height for boats needing to pass, which matters for lift and dock planning.
- Shallow bays. Dona Bay and Lyons Bay run shallow throughout, so depth at mean low water is checked early in any project.

Does the Blackburn Point bridge limit what boat I can keep in Nokomis?
If you need to pass under it to reach Casey Key or the ICW, yes — it's a fixed-height swing bridge. We factor that into lift and dock recommendations.
Who permits dock and seawall work in Nokomis?
Sarasota County, plus FDEP and the Army Corps for in-water work.
How shallow are Dona Bay and Lyons Bay?
Shallow throughout much of their extent. We check depth at mean low water before designing any dock or lift.
