Daggerboard Repair

I repaired a similar ding for a friend not so long ago but it was more like a bite out of the trailing edge and I had the pieced that came out. I drilled a couple of holes and epoxied in some stainless screws which I had removed the heads and filed smooth (in case the repair fell out leaving the screws behind).

I then bonded the new bit back on and filled in any gaps with epoxy, Coloidal silica and glass bubbles, sanded it smooth and put a really thing layer of gelcoat over the top to get a nice finish.

If you don't have the bit that's missing tape some plastic sheet to one side and build up the shape with epoxy, coloidal silica + glass bubbles. Let it set, remove the sheet and fill any holes etc with gelcoat filler. You could just use just gelcoat filler if the area is small and this will give you a 'sacrificial' tip which will fail before the daggerboard case if you hit something. You will have to replace it often though if you throw your board into the boat every time you come ashore.

See below for suggestions as to why this is the wrong thing to do and the correct way to do it any time now
