The GEMINI WAVERIDER 505 Coach Boat was constructed at Berthon, after receiving extensive input from experienced sailing coaches on what should be included in a Sailing Coach Boat.  Using this feedback, we have fitted out a boat truly designed for purpose.

This WR505 is tough enough to withstand the demands of coach boat duties but at no performance compromise.  Built for the job, it is an intuitively laid out boat with features perfectly suited to the demands of a small-boat coaching craft.
