Designer's Comments

Tern is a lengthened (to 23'9') version of Ratty, but built in a very different configuration and using bolted lapstrake plywood rather than epoxy bonds. The planking is screwed to yellow cedar frames and her interior is completely open in the traditional manner. Another major difference (PDF, WoodenBoat #175) from Ratty is the change to a foil shaped wooden centerboard rather than Ratty's flat steel plate.

Tern at anchor on the north coastTern was designed for a group of young people to build and then sail or row roughly 2000 miles to Alaska and back. Their story (also WoodenBoat #195) of their 3-month long voyage from Lopez Island to Revillagigedo Island and back again includes tribute to Tern, who kept them safe and got them home through many adventures.

The photos (except for Tern at anchor) were taken by Cameron Eckhert (Classic Boat, July 2007) during Shipyard Raid 2006.
