What do we need?
Normal windsurfgear is OK, just don't rig way to big or small. With freeride gear 30kn is possible but you need some more wind. I would advice to reach 30kn boardspeed in 20kn wind. Look to the How To: Do Basic Tuning to get a fast setup for all conditions.
- Search for some flatter water, with possibility to go downwind
- Go crosswind as fast as you can
- Wait for a gust and go downwind, DO NOT hang harder into the sail in the gust. By keeping the sail in normal stance you will be faster.
