Ness Yawl/Arctic Tern

[BDann]

Anyone know what sort of building technique is used for these boats? I have been looking at a glued and screwed lapstrake design (Penobscot 17). What would the difference be?

Similar but without the screws.

Brian,
As I'm sure you're aware, both the Ness Yawl and Artic Tern are double-enders designed by Iain Oughtred. They also used glued ply construction, similar to the Penobscot 17, with one significant difference. The P17 uses stringers, which remain a permanent part of the boat. This makes determining the shape of planks (spiling) very easy, but you have to work around them when you flip the boat over and start working on the interior. I don't believe the Oughtred designs use stringers, or if so, they're temporary. Oughtred wrote a very good book on glued ply construction, it's worth getting no matter whose design you choose.

Brian,

A very active discussion forum on building and sailing Oughtred's beach cruisers will answer some of your questions: CY Forum (http://www.mavc2002.com/cyforum/index.php)

I am building a Caledonia Yawl, a larger version of the Ness Yawl, using the same glued plywood lapstrake construction. See an overview of its construction: Reina del Llano (http://www.kenleap.com/boat.html)

I second Al's recommendation about Oughtred's boatbuilding manual--an excellent reference for glued plywood construction, regardless of design.

What Al and Ken said. The current issue of WoodenBoat, #183, has the first of a 3 part story about building a Caledonia yawl. The Ness yawl and Arctic Tern are baby sisters to the Caledonia yawl and the construction is quite similar. No stringers used or required.

Great boats, bye the way.
