Farrier will not allow Kevlar on the outer skin, not sure why, can anyone enlighten me, he also is quite open that you can use carbon on the outer skin but to get dramatic weight savings, the skins become so thin that they cannot withstand the impact loadings of crashing into things. He advocates glass and a good layer of it as it is very resillient to dings etc ?, easy to repair, cheap to manufacture and does the job, any weight savings can be saved elsewhere. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
