A stable outrigger would be great, no doubt. Stable against what, though? The North Atlantic in winter would defeat ANY outrigger, in my opinion.
It would defeat most "Western" designs too, but it was the effort to survive in such conditions that forced the evolution of (e.g.) the Bristol Channel pilot cutters: heavy, seaworthy hulls, of immense strength, designed to stay at sea in almost any conditions, and capable of it too.
I wouldn't like to hang around the Western Approaches in October, sailing a Pacific Island outrigger canoe. Nowhere to put the coal fire, to start with.
That's fair enough and I replied:
My design, which I should scan and put up here, uses the dugout for a start - two inch thick and monocoque. It has an equally solid top, creating a cocoon and only two entry points in the one long hull. Etcetera, etcetera, etcetera ...
All right, today, I think I finally drew it all together. It sounds like a hotch potch and most of the work was drawing, rubbing out, redrawing, not trying to emulate any particular style but drawing from them. It has aspects of the Viking longboat - 51 feet long and 7'9" wide at the beam but 3'6" at the waterline, high prow and high stern to break coming and following seas. Freeboard is 3'6" at the lowest point but the four beams to the ama are at 4'6", chocked at the gunwhale.
It's a curved cabin roof using the same lines as the shell, no need for any deck area, quite heavily built with stringers and arched ribs. There's only just standing room inside at certain points, to keep it low and lean. As usual - shoal keel and underslung rudder, with two masts and a cross between the junk and the Scottish lug rig, stylistically more suited to the longboat.
Blending the outrigger into the design was difficult but the ama is a more slender version of the main hull, with added rocker, high prow and stern. The construction would be traditional clinker/lapstrake. It does look cool, though I says it who shouldn't and the motion through the water would be sublime. Gosh I'd love to build this and put to sea in it with a crew of three.
In the meantime, I'd love to scan my sketch and show you but I need to buy a scanner first.
