CL 420


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.

With the impermeable qualities of our aluminium hulls there’s no need to worry about gelcoat chips, or putting the boat on a beach or a trailer. Your Highfield Classic won’t delaminate over time, retaining its agile performance and weighing the same in 10 years time as the day you towed it away from the showroom.

All Classic RIBs are easy to trail, easy to launch and recover and due to their light weight and integrated davit lifting eyes.

The hull of the Classic 420 is built of 4mm thick powder coated marine grade aluminium. The tubes are made of 1100 dtex coated fabric.
