The Ultimate 20 was the result of a team of sailors with impressive credentials. Jeff Canepa headed a team that included Jim Antrim of Antrim Associates-Naval Architects, sail maker and Olympic medalist Jay Glaser, and 505 builder and foil specialist Larry Tuttle.

Their idea was simple. Create a monohull with multihull performance. They wanted a dry and stable platform with safe interior space for kids or crew. They also wanted a lightweight trailerable to have responsive dinghy-like handling, all with the cockpit comfort of a 30 footer.

After years of prototype testing, the U20 team achieved the perfect blend of size and simplicity, creating the ideal boat for racing ONE DESIGN, PHRF or any weekend sail about. The U20’s design offers exceptional craftsmanship that is reliable, safe, economical, and fun to sail.
