Small catamaran hull boats. This type of hull design makes it ideal for use in choppy water, like in bigger bodies of water... i.e. bays, large lakes, inter-coastal, or beach areas. V hull boats also work good in chop, but lack the stability at a stop. These make great yacht tenders and fishing boats, because loading onto them from a dock offers superior stability. The cat style hull out performs pontoons because of hydrodynamics and increased overall buoyancy.
