Gellcoat filler on its own will be no good if it is below the waterline, you will need to clean out the crack and discover the full extent of the problem before you decide on the right remedy.
I would be happy to have a look, or there may be someone in your area that can give some free advice but I would not suggest a quick fix.
Not too helpful I know, but you should be wary.
