Use polyester resin and filler powder NOT epoxy. All the damaged area has to be dug out back to sound glass and you will probably have to devise a method of clamping it.
And make sure you remove all the glue residue near the joint that came from the gaffer tape. Edited by Garry |

If you do the scraping out and the "bog" properly, there will be no need for the glass tape, so leaving the gunwale looking as it did before.

a nice bog of epoxy and microfibers will be very strong and then possiably wrap some glass tape over it all. you can get all of this stuff online from shops like purple marine ldc northampton sailboats |

Mending the 420 is more like mending a Laser. You have to turn the boat over, dig out all the glop round where the joint has failed, as Jeffers says. I know most professional repairs say to use the same material to mend the boat as was used to build it, in this case thickened polyester resin. I've both used epoxy and polyester on these jobs in the past, and found both work. Most important thing is to get rid of what was in there first, even drilling down into it or using a router, if you dare!

The Hobie Tiger trick to solve leaky dagger board cases is to thin out some polyester resin and then pour it inside the hull and rotate the hull to get the resin to the leaky joint - just leave the inspection hatch open long enough to vent the thinner and don't put a match inside it to see if it has gone off... |
