Protective Bottom Painting

Whether you've just bought a new boat or are repairing a classic, a good bottom job is a wise investment of time and money. Bottom paint is a specialized coating applied to the hull of a ship or boat that slows the growth of subaquatic organisms that attach to the hull. Left to their own devices, these organisms can adversely affect your vessel's performance and durability. Our professional crew will prepare your boat for a success bottom job as soon the hull clears the water.

Prospeed Application

Propspeed is a foul release coating system designed and proven to prevent marine growth from bonding to metal surfaces below the water line.
Propspeed gives your props and running gear a long-lasting ultra-smooth surface, preventing fouling and giving you more speed.

Shrink Wrap

Encasing your boat in shrink wrap is a great and economical way to protect it from harsh elements like dirt, dust and sun. Here at Key Largo Harbor Marina we offer shrink wrapping to protect your investment.
