Delta series


Our Delta wing paved the way to a completely new category of fins. Inspired by the aeronautic Delta wings, Rick has transferred the special aerodynamic features to windsurfing applications:

  • very short wing span combined with a large area,
  • very thin and stiff profiles,
  • high rake between 50 and 55 degrees and
  • additional lift due to leading edge vortex at high angles of attack.

All these features make the Delta fins the ultimate tool for shallow spots, extremely weedy conditions and speed sailing. Compared to a straight freeride or slalom fin, the fin length can almost be halved. Combined with the high rake, the danger of injury by touching ground is greatly reduced. Speed sailors can finally use the flat conditions of tidal waters for even higher speeds, over 40 knots were easily made. Our Delta wings are fast, easy to control, have great upwind abilities and jibe great in wide and medium arcs.

The carbon version is extremely light and aims for bigger boards, up to Formula race boards.

The new Delta-XT-50 (only Delta-fin in our range with a lower rake of only 50 degrees) was thoroughly tested in Denmark and Australia in water depths between 10 (!) and 30 cm and is the new benchmark for extremely shallow spots and heavy weed.

Tuning tip for Delta fins: Avoid too much back-foot pressure – especially when not fully planing – and keep the board fairly flat (nose down). That will help you to avoid spin-outs.
