Centurion's unique Reverse Shoebox design fits the boat deck edge inside an upturned flange at the hull edge. This design eliminates the possibility of water intrusion unlike the "shoebox" method used by other manufacturers, whose deck overlaps the hull leaving room for leakage. Bonded together as an integral part of ICS the Reverse Shoebox helps make Centurion boats the strongest, most leak resistant boats in the world. The Plexus bond is literally stronger than the laminate.
