Almost a classic case of how most people misunderstand the concept of Kevlar and Carbon. In actual fact Kevlar is worse than glass for load impact on the outside of the hull. Farrier for one will not allow Kevlar on the outer skin. Equally Carbon is terrible in an impact situation, yes it maybe terrifically good at bending loads but once it reaches its limit it simply breaks.

Kevlar is great for wear abrasion, just try and cut it in its cloth state without having been set with epoxy, its very difficult, put Eopxy in and set the cloth and you can cut it relatively easy, try sanding ( abrading ) it though and it becomes the repairers nightmare, the very reason Stealth will not use Kevlar on the outer skins.

For me Kevlar is not the remedy of damaged hulls from beach landings, no matter what you put on that bottom of the hull, it will get shredded by those even harder and sharper rocks etc that beaches are made of. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
