INTERNATIONAL THUNDERBIRD CLASS ASSOCIATION
More than just a sailboat…a way of life.

The International Thunderbird Class Association is the governing body of the Thunderbird Sailboat. The purpose of the organization is to promote and develop the Thunderbird class under uniform rules. The organization maintains “The Black Book” which specifies measurements and required equipment in order to preserve the one-design status of the boat.  The ITCA also sanctions regional and international events, maintains a roster of paid membership and boats, and is responsible for rendering decisions on boat measurement issues.

Twelve “Birds” convened at their primordial home, the Gig Harbor BoatShop for some low key racing and high level partying. The event was co-hosted by Thunder bird Fleet 1 and the Gig Harbor Boat Shop and both groups are looking forward to more cooperation and collaboration. The racing on Saturday was like speed dating.
