Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts in Ellenton, Florida, in Manatee County. Ellenton sits along the upper Manatee River, further inland than Palmetto or Bradenton, where the water runs lower-salinity and more tidal-influenced-freshwater than the river's mouth. That changes both the environment materials have to survive and how a dock or seawall is designed.
Marine construction services in Ellenton
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
Upper Manatee River docks see less salt exposure than a coastal dock but still face river current and periodic flooding. We build new docks and handle repair, replacement, accessories, and canopies and shade covers.
Seawalls
River-front seawalls in Ellenton carry a mix of concrete and vinyl, and lower salinity slows but doesn't stop the usual aging. 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 river's current and depth. Repair covers cables, motors, bunks, and controls.
Dredging
Upriver stretches and canal ends can silt in. 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 Ellenton
Marine construction in Ellenton is permitted through Manatee County, along with the Florida Department of Environmental Protection and U.S. Army Corps of Engineers for work below the mean high-water line.
- Upper-river conditions. Water here is less saline than at the river's mouth, and freshwater inflow varies with rainfall.
- River current. The Manatee River carries real current upstream of the bay, which factors into piling and dock design.
- Seasonal flooding. Heavy-rain events can raise river levels quickly, which is a factor in dock and lift elevation.
- Manatee zones. Slow-speed protections cover much of the river.
- Gamble Plantation Historic State Park. Florida's oldest surviving plantation home sits on the riverfront in Ellenton, and waterfront near the park boundary gets closer historical and environmental review.
