Pathfinder boats are built with a vacuum-assisted resin-infusion process called VARIS, which bonds fiberglass and composite materials into a strong, light hull. Like most modern fiberglass boats, Pathfinders use foam in the hull for added stiffness, sound dampening, and buoyancy. Because Pathfinder bay boats are generally larger than 20 feet, they are not required to carry full Coast Guard level flotation the way small skiffs are, but the foam and composite construction add a solid, safe feel on the water. For the exact flotation details of a specific Pathfinder model, it is best to check that model's specs or ask a dealer.
