These guys are pretty international....this link should bring you to the 2 oz. cloth section.
Here is a link to get some Kevlar...it is very hard to wet out I have heard but it would sure sheath the hull.

The thing about f'glass is that it is not very abrasion resistant. If we're going to go through the work (I too am beaching on jagged rocks), perhaps we should think about Kevlar or Dynel is also abrasion resistant. Dynel apparantly does better vacuum bagged in place b/c it swells. These latter cloths are going to be expensive, unfortunately. The Defender link has a 1 oz. 'angel hair' f'glass cloth.
I've seen it done, but what is your though on Kevlar Michael for those of use whose beaches are rock?
Cheers,
Clint
