The concept of flotation has been around for centuries; it is simply a matter of displacement. Even today, logs are used in the Pacific Northwest to float docks and marinas. In the olden days we floated docks with steel drums which worked great assuming they were sealed properly. Inevitably, steel drums rusted through and sank like an anchor. Dock builders eventually adopted the familiar white foam floats used to float dock frames; these foam floats were later banned due to environmental concerns. Today, the standard dock float consists of white foam encapsulated within a polyethylene container. As in any industry, certain manufacturers produce a better quality float than others. Key items to consider are the thickness of the molding, whether the float is seam or 'roto-molded', the location of seams, the construction and location of bolting flanges, the basic shape of the float, the location of vent holes, as well as the length time the manufacturer has been in business, and their financial stability and market presence.
BENEFITS
Rotationally molded shell-corners build up material for strength where you need it.
One piece shell-no seams to split or leak
Molded holes and slots in flange to bolt direct to frame-no screws penetrate our watertight containers.
Ribbed design for extra strength if the dock sits down on the ground.
Vent plug to completely seal container after installation-most floats leave the vent open which can leak
Myriad sizes to engineer buoyancy so dock floats level
