They're always good reading I suppose chines affect the resale value, as you have noted previously, of that tiny fraction of people who aren't...
Being an avid reader of Old Multis posts, that state that most beams are designed to be 5 x breaking strength[Crowther]., 5x overall weight of...
That is neat, I'll be having a serious look at my leach/clew, that is an extra extra dimension for me to learn about, an extra knot even...
From what I can tell older designs have more rocker and seakindliness, rocker is dropped for speed, just get there quicker. The correct approach...
Hi and welcome, it depends on how many teeth and quality your blade has ,the more the merrier, speed , and how accurate your table is . you lose...
Polyurethane foam is easy to work and can be a lot cheaper. You rely on the outer glass skin and deck join, stringers etc for strength . Old...

I was relieved when the dagger boards winkled out, getting close to glassing the 2 parts -hobie 16 and maricat which overlap on the new dagger...
That looks good, I'll be interested to see how you go about spreading the shearing force-load,the bulkhead looks like it could act as a...
I hadn't used this biaxial 45 400gsm x 150mm before, I'm beginning to think it's me [probably is] but it seems to require filling after each...

I wont be using epoxy for a while "dyneema is compatible with epoxy resin so it can be used just like glass cloth/cf " to quote Bottman , so...
If the dyneema absorbs epoxy it would be better, we'll have to do some tests. You could make a simple internal frame out of dyneema, standard...
Hi, it's mentioned by Bottman just before halfway down the page, ...so Ultra High Molecular Weight Polyethylene (UHMWPE) is able to absorb...
