The double hull yachts sized from 400cm to 700cm, we call patrol boat. Aluminum patrol boats are made of 4mm thick powder coated marine grade aluminum for boat hull and 1100 Dtex pvc fabric or 1.0mm hypalon fabric for inflatable tube. Internal under deck fuel tank, non-slip and self-draining deck, strong inside keel let you take on even the toughest conditions confidently.With the impermeable qualities of our aluminum hull, there is no need to worry about gelcoat chips,or putting the boat on a beach or a trailer. Patrol boat is easy to trail, easy to launch and recover due to their light weight and integrated davit lifting eyes. They all can be towed on an unbraked trailer.
