G'day Simon,

I noticed the photo of cracking on your hull and thought I should speak up.

I repaired a similar crack on my hulls with carbon fibre on the inside of the hull. The inside ply had a slight crack about 15mm long running down it too. The bow broke off eventually with what we suspect was the inside ply buckling right on the crack.

This needs to be repaired properly, and you might as well do both hulls at the same time.
