It settled on a PVC-foam core, which bonds to the boat's resins and fiberglass and does not soak up moisture. The fiberglass stringer grid, meanwhile, is glued and glassed into place, as are the floor and bulkheads. Jones Brothers uses a resin in its hulls that allows the various parts to melt together, which results in a solid one-piece design from the hull's exterior to the floor. What's more, with the exception of the center of the hull (where the glass is at its thickest), the widest unsupported span is only 8 inches. This results in an extremely durable hull and quiet ride.
