Description

The SeaWind One Design model sailboat is a 1-meter replica of an America's Cup yacht, manufactured by KYOSHO and distributed in kit form through hobby stores worldwide. The kit ($290, or ready to sail with radio, servos and batteries for under $400) is designed with an excellent instruction manual, for simple home assembly without special tools. The finished boat "out-of-the-box" delivers excellent performance satisfying to novice and experienced skipper alike. The SeaWind Resource Center, affords access to tips on building, tuning and sailing while also providing a communication center for skippers through its forums.

The boat itself is made of sturdy ABS plastic with aluminum spars. A few early kits (SeaWind SE) were supplied with an alternative fiberglass hull, and sale of these kits has been discontinued. The initial Class Rules tightly control the boat elements close to the kit to ensure new skippers are not faced with a costly refit to be competitive while allowing minor modifications to rigging (materials and adjustment methods) to facilitate tuning and to the hatch cover to ensure watertight integrity.

AMYA members with SeaWinds and new skippers, please register your boat when you renew or join so that the Class Secretary (above) can contact you.
