Closed Bow banana boats are developed as a streamkined construction.
The main body of most banana boats on the market is made of 4 separate pieces that are then glued together. This type of construction leaves many gaps and spaces for water to get into and add stress on the banana boat and the tow boat.
Closed bow banana boat is shaped more like a standard boat hull and is all one piece which means no gaps for water to get into. This streamlined construction allows the banana boat to go through the water more smoothly with less drag. This takes stress not only off the banana boat but also the watercraft towing it which equals a longer life for the banana boat and better gas mileage for the watercraft.
