Highfield Ocean Master 590T

The flexibility and adaptability of the Ocean Master design offers fitting options that create either a nice riding boat, a sharp fishing RIB or a hard working support vessel. Whatever layout you choose, you can be assured that your Ocean Master is built to last. The Ocean Master range is designed with tough conditions in mind. Internal under-deck fuel tanks, non-slip deck, self-draining deck and a 24º dead rise let you take on even the toughest conditions confidently.

With the impermeable qualities of our aluminum hulls there’s no need to worry about gelcoat chips, or putting the boat on a beach or a trailer. Your Highfield Ocean Master 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 Ocean Master RIBs are 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.

The Ocean Master 590T is made of 4mm thick powder coated marine grade aluminum for the hull and 1100 Dtex fabric for the inflatable tube.
