I thought it might interest a few people to see how I repaired a close encounter with a pointy rock.
The damage, clean through the glass and about 3mm into the wood:
I taped a steel ruler onto the hull next to the damage, and used a box cutter with just a couple of mm of the blade showing to cut around the damaged area, one strip wide:
I then used a flat chisel to make a shallow hole:
Cut a piece of strip to fit the gap:
And glued it in:
Planed it flat (the plane is a Veritas Miniature, all I had handy)
Cut a scrap of glass cloth to cover:
Wet it out and filled it:
And sanded it back flat (actually, I will have to wait a week or so for the epoxy to cure fully before I can sand it really smooth)
All in all a couple of hours easy work.
So go rock gardening, even in a fully (80kgs of gear and water) loaded North Star!
Yes Rob, my brand new one, second day in the water :-)
