Naish S25 Assault Windsurf Board

Naish S25 Assault Windsurf Board

Available Sizes: 75, 85, 95, 105


The Assault is for any wavesailor who needs a board to perform in a broad range of
conditions. Keeping versatility in mind, these unique boards combine early planing with
the turning ability of a pure waveboard. The Assault shapes are easy to ride and feature a
flexible 2+1 fin setup opening the door to a wider range of conditions and fun! The boards are supplied with a single fin and cover up boxes for the side fins. Having the Slot side fin boxes available opens the door to tune the boards even further by using a thruster fin set, which can be purchased as an accessory. Riding the boards with the single fin configuration emphasizes the early planing performance and speed, and is ideal for side on, onshore and even flatwater. When used as a thruster setup with smaller center and side fins, the turning radius of the boards will tighten making them suitable for an even wider range of wave conditions.
