It seems that a perfectly round mast *with a sail behind it* produces power. Strange but apparently true. And it explains why folk like me who...
Its all in the thread somewhere, but you could lose the will to live finding it. There are two issues. The first is that our understanding of...
Looking at the drawing there seems to be a lot of turnup in the hull aft as well as the small rudder. That might make for a craft that rolls and...
I think I would want to investigate why he is capsizing rather carefully. 36sq ft is not by any standards a particularly large sail, and he ought...
The issue you have is that whatever device you fit to provide side force in the water will have much the same load on it as the sail has in the...
Might be better expressed as the centre of buoyancy moving well to leeward of the COG. Same effect.
Traditionally one simply dipped the screw in varnish before inserting it, which both lubricated the job and provided water resistance. There are...
My feeling is that you are at some risk of over complication. The historically popular rig for a sailing canoe, by the way, was two masts, each...
I can't think of any reason why a rig would settle at an optimum angle of attack. Rather the opposite.
Dinghy sized sliding gunters were popular in the mid 20-th C. One of the appeals was indeed fitting the spars in the boat. Unlike a gaff rig a...
I wouldn't cut the existing spar. Not everyone finds sliding gunter rigs quite as congenial as their enthusiasts. Rigging the boat with a gaff...
Yes, don't underestimate the loads on the leeboard, as a rule of thumb assume they are pretty much exactly equal to the loads on the rig.
If you are determined to try a leeboard then I think you'd be well advised to rig up something, preferably without making too many holes in your...
Well, all you can do is to draw things and explore options. Everything is going to depend on everything else if you know what I mean. I imagine it...
The Farr 3.7 would seem a logical choice. Pedigree boat from one of the great designers, and CAD file available so you can get a plywood "kit" cut...
The classic decked canoe cruising rig was actually two unstayed masts, one up in the bows and one behind the crew. That does impose quite a...
People home build in foam sandwich regularly. Its not a big deal, indeed easier than plywood. Have a read of this. Building in Foam Sandwich...
Classic Moths and the like don't really plane well when heeled, so I don't think they constitute a great model for you. I struggle to think what...
AIUI most commercial design courses major on motor craft. This may simply be the first time the OP has had to consider a sailboat. But I suspect...
Basically boat designs don't scale very well, especially to such an extreme.
