RB 21 cabin is a comfortable day cruiser with a cozy cabin. The facilities include: sea toilet or chemical toilet, washbasin and a double berth.

Its traditional lines and strong construction in combination with a modern hull below the waterline, ensure agreeable and safe handling for many years. The hand made teak elements such as the helmsman seat and forward bow seat, or stainless steel fittings such as cleats, rod holders and navigation lights, as well as hand laid gelcoat and GRP laminate, grant the RB 21 elegance and solidity.

With bracket mounted outboard engines up to 135 hp, the boat reaches speeds beyond 35 knots. The RB 21 cabin is not only perfect for day cruising, but also as a platform for fishing or scuba diving.
