A new design, combining aspects of both the thick and thin designs I posted previously. Skinny (low angle) bow, for humpless planing (small bow...
Alright, I was already a bit suspicious myself, but on 'Shu's' I14 build (http://forum.international14.org/viewtopic.php?f=2&t=865&start=315),...
I was using the layup given on the Cherub website. http://www.uk-cherub.org/doku.php/tech/foam_sandwich. Bulkheads: Transom/Mid Dance Floor/Front...
I might go to 1/4" foam too, what do you guys think?
For laminating the hull (I'll be using a male mould), could I laminate the inside of the foam before placing the foam onto the mold? Then it would...
I was thinking more wind-speed wise, but it sounds like it wouldn't really carry over to my boat- that's an awesome project by the way though,...
Alright, thanks Doug. So when do you expect to start depowering with your Crossbow? I'll be somewhere around that range.
Also, why is an F18 so high?
Doug- Taylor's Formula is not actually the name of the formula I was using, I must have remembered incorrectly. But it calculates the...
Plugging that in to Taylor's formula then gives me around 16 knots for the speed at which the force is 0.8 lbs/sq ft. That's good, but maybe a bit...
I'm getting 0.8 for lb.sq.ft max pressure... That means that I'll be powered up in lighter winds, than the Windmill for example, right?
yeah, I meant that as a performance comparative measurement, I'm leaning more towards throwing out the lever arm. I'm not going to disregard it in...
*Bieker not Bethwaite in the list of designers
Yeah, while I agree with Bethwaite that the larger the arm the more the heeling force, a higher aspect ration sail also creates more power- so if...
I've also been hearing recently that the lever arm part of the SCP/W ratio isn't very effective- something that makes sense to me. It seems to...
Also, what about using balsa as a core material? I know that it can be fairly light, and its cheap. Would 6 oz glass/ quarter inch balsa/ 5 oz...
Yeah, I've pretty much shelved the idea of a full rigged boat, I'll go with the main only setup. Any comments on the design last page?
Doug, I know this is crazy, but I keep wondering about going with that full-size I14 rig. People have told me that the main problems I would have...
Alright, I don't have the sails with me to measure- I reverse calculated the the I14 ration of 0.35, plugged in minimum weight, and two 180 pound...
which is 1440 ft/lbs
