Recoat with epoxy and try to find better than a one to one epoxy. Resins 2:1 or more are harder.
On the bottom, mix the resin with graphite power, it is inexpensive and very hard.

Re: Stuart's D5 Dinghy.
Thanks Jacques. I used west for the build but only have a little left. The damage was largely to a non structural area. I won’t be putting the outboard there again so I hope to avoid repeats. I am thinking about graphite on the bottom though it’s not easy to find in NZ except art supplies or small bottles for keyholes. I used west 420 Aluminium powder which seems to have given a fair bit of scratch resistance.
Good info about the epoxy.

Re: Stuart's D5 Dinghy.
You had me considering aluminum. What caused those scratches? Logs. Sand. Buildings?

Re: Stuart's D5 Dinghy.
Scratches to the bottom are largely river stones and boat ramps (the small ones that barely mar the surface.) The deepest scratch I am pretty sure is either the time I scrapped over a rock at low tide with two in the boat or scratches from the steel trailer I put it in. The side scratches are definitely that trailer but they don't bother me as it's paint only. The epoxy I put on under is untouched. I covered the whole outside with a coat of aluminium powder epoxy mix.
I have worked on my trailering technique and now have a decent mat and groundsheet to lay it on. No damage since. I am putting it down to teething issues rather than the materials or use of the boat.
The launch wheels work a treat. The skeg hasn't been called upon to take any damage at all yet. I put the wheels down in the water and nosy in to the ramp.
I did buy some flatbar aluminium for $5. 1m by 20mm by 1.6mm. About 3.5' by 1'' by 1/16''. I'll glue it on at the end of the season or earlier if I get around to it.

Re: Stuart's D5 Dinghy.
Cheers. It was definitely a learning experience. I am taking more care with my second build. Bought a quality jigsaw with clean cut blades and decent circular saw. Also a full size set square (probably one of the biggest omisions in the dinghy.)
