Hull damage below water line - How to repair?

[sailingjupiter]

On launching my boat off its trailer yesterday the side of the front roller of the trailer scratched into and beyond the antifoul. Not really deep but still a cause for concern. Boat had an epoxy layed applied 4 or so years ago so I presume this has been damaged.

Will it be OK to leave until the end of the season? Is there an epoxy type putty that will cure in the water? Or does it have to be out of the water to work? I don't really want to have to get the boat out again as its such a job on our club slipway.

Would you leave it or sort it?

Thanks

Was up at the boat on Windermere last week and a guy arrived with a yacht that had lots of deep scrape marks and half a roll of duck tape covering the starboard side of the boat, trailer backed down ramp, wardens took a look, boat in water, boat out of water, passed boat on its traler near the M6 later on...

My trailer bit a lump out of the bow well into the glass about 4" below the waterline. I dried out on the beach on the next tide and filled the hole with gelcoat filler. Seems to have lasted 3 years without any evidence of trouble.

I used a product called suncure i think. some sort of resin striaght out of the tube and sets clear and very hard in less than 1/2hr on warm day.

Looking round the net it looks like Starbrite do a repair epoxy putty that cures in water.

Anyone got any experience of it? A lot less trouble than getting the boat back on its trailer for half a day.

This stuff works fine. Knead up enough between your fingers and force into the gouge with a wooden spatula.

G'day springjupiter,

Would be better with a picture, but from your description I would say don't bother till you haul out next time.

I would avoid using any temporary repairs as applying a putty will only seal in any moisture, better to wait till she is out and the area has had time to fully dry.

Remove the Anti fouling and sand the area with a 200 grit and let it dry, then clean it up again, wash with Acetone and apply 4 coats of epoxy resin wet on tacky to avoid sanding between coats.

If the mark needs filling, use closed cell balloons, let them cure then sand and coat as above.

You may need a coat of epoxy primer over the finish as not much sticks to epoxy, just sand the finish after it's fully cured with a 200 grit; just enough to remove the high gloss and no more.

Hope this helps.
