Osprey Double

Project Summary: This was a fast build–21 days from delivery of the kit to water-ready. I used every trick to make this schedule, which did not include varnish. I think if you were experienced and were a little more careful in planning out each day, you could do it in 18 days, but that would be pretty much a full-time job. There was no particular reason for going fast except I wanted to see what was possible and I had a month available.

There are many more details and tips in the pages relating to the Tern 17. Some are repeated here, but not all. I recommend taking a quick look through those pages if you are a new builder looking for all the tips you can find.

This boat is highly modified. There are two additional hatches and storage compartments along the sides, running from the rear seat to the forward seat. This modification took an additional 10 days–every piece had to be cut to fit. One additional sheet of 4mm Okume was required–purchased from Aircraft Spruce for $56. They cut it into five pieces, per my drawing, and were able to ship a 46″x24″ package for $16. This photo shows the boat prior to cutting the added hatches.

Making Some Final Rudder Control Measurements

Why a double Osprey? Pros:

  • Fast
  • Stable
  • Good, maybe great, fishing platform
  • Rudder
  • Increased safety for a less-qualified paddler
  • Provides an easy way to include friends in day paddles


  • Big
  • Less water-tight storage than a single, and less storage overall
  • Sometimes called a “divorce boat”
  • Footbraces are very wide (and uncomfortable, IMHO) for the rear cockpit. This was fixed as part of the modification.
