Orca 21
Designed by Evan Gatehouse
A 20 ft 9 1/2 in double or triple expedition sea kayak designed by Evan Gatehouse for Bateau / Boat Builder Central, plan SK21. Built to carry a large load on long trips, it has the peaked foredeck of the Orca 17, a moderately high bow and a shallow vee hull with good initial stability. Beam is 30 in and the bare hull weighs about 61 lb.
Stitch and glue in thin 4 mm plywood with light glass. Not difficult, but recommended for builders with one stitch and glue project behind them. The designer's estimate is 40 hours; a more typical budget is 90 to 150. Measured medians from build logs appear below.
What building a Orca 21 actually takes
Medians from the build logs kept on this site, not the designer’s estimate. Nobody has logged this boat here yet, so they are empty until the first builder does.
Those medians firm up as more people log this boat.
