RS Sailing
RS 400

The RS 400 is a double-handed dinghy, not equipped with trapeze. She offers in return, to master the power, a large deck width. In order to adapt to a wide range of crew weight, she is equipped with adjustable spreaders to bend the mast, thus reducing the power of the mainsail. The sail area remains significant and the asymmetric spinnaker allows excellent performance.

With over 1000 copies sold is now a classic that is regularly seen in race, especially in the UK.
