Understood, in this type of repair one fiber type alone will work better than a mix of fibers. Many thanks to both of you!

I wonder if it makes sense to mold glass battens directly over the healthy hull, together with the patch lamination.

A question:

The inner skin will result stronger than the outer skin. I'd feel safer with the opposite. Considering that we'll have a relatively wide access to the inside, is it possible to patch the OUTER skin from the inside? (At least the big rupture?)

It would require the opening of a wider rectangle from the inside, by means of removing only the foam and inner skin to leave enough space for the patch under the outer skin repair.

The patch would be glued to the outer skin and then glassed from the outside to the right thickness. Afterwards, foam and inner skin would be glued to the inside. Or maybe the foam could be pre glued to the patch...

The other repair method would be used for the smaller rupture (or deck)

Cheers,
