The Seaclipper 10 is a solo trainer and harbor racer is fun for the entire family. The crew sits in a secure cockpit, steering with foot pedals, with all sail controls arranged on a dash board, close at hand. Performance is lively, with good steering control in a comfortable, forward facing, semi-reclining position. Construction is beginner level stitch and glue plywood using epoxy adhesives. Most components are ¼″ thick plywood and ¾″ thick lumber. The mast and demountable cross-arms (akas) are aluminum tubing. Expect to spend 3-6 months part time effort to complete. Plans are well illustrated and easy to read. The overall beam is 8′ for trailering.
