The Classic 420 (previously named the Ocean Master 420) design offers fitting options that create either a fabulous family cruising RIB, a luxury tender or a hard working support vessel. Whatever layout you choose, you can be assured that your Classic is built to last. The larger models in the Classic range have been designed with tough conditions in mind. Internal under-deck fuel tanks, non-slip deck, self-draining deck and a 20º dead rise let you take on even the toughest conditions confidently.
