Cracked Fresh Water Tank Fix???

[Joesplace]

Hi - I've got a hairline crack in my fresh water tank near the top seam. Does anyone know of a way to repair beside putting in a bag? Yes, the water tank is built into the keel glass - no easy way to remove . . .
thanks,
joe

Fiber glass it?

Capnblu - good idea but it's just outside of my reach. It's about 4 foot away from the fill hole.

Drill a hole at each end of the crack to stop its spreading. Then seal that crack with similar material that the tank is made of.

Some tank skins crack from flexing and you may want to re-enforce the top in order to reduce that flexing.

Thanks everyone - I'll see what I can do next weekend . . .
