The Artic Tern is another "largish" double-ender dayboat or camp cruiser..

Artic Tern can also be rigged as a lug yawl....Skips friends boat is rigged this way, or it can be set up as a gunter sloop.
Artic Tern, at about 18 feet is a bit smaller than the Caledonia Yawl at 20 feet, and weighs rather less. It's still large enough for two, but not so heavy as to be completely miserable to row. The "evolution" of all these open yawls, is....more or less.... the Sooty Tern. Now, "evolution" of these designs is kind of debatable, as the workboats on which they are based have been in existence for nearly a thousand years. They are not far removed for the Viking faerings. Nonethless, here's a Sooty Tern. I believe the Sooty Tern came about through correspondence between James McMullen and Ian. James had built several of Ians designs and had some thoughts about changes he wanted to see. Basically, he wanted permission to pen some modifications. Ian consented, there was correspondence. Drawings went back and forth, and in the end.....Sooty Tern.
This is Jame's Sooty Tern, "Rowan"....the boat that really set the hook in me on the whole concept of small, double-ended boats for sailing, rowing and camp cruising. James and I have butted heads pretty hard on the Wooden Boat Forum, but I gladly acknowledge his supreme skill as a boatbuilder, and how his interaction with Ian has produced an absolutely lovely design.
I hope you've enjoyed our sail through the designs of Ian Oughtred, one of Scotlands best-known small boat designers.
