You could rhino line or line x the inside and get it color matched and it will NEVER leak again . I have seen it on John boats and canoes , line x is thinner therefore lighter , rhino is kinda think and may add quite a bit of weight . As for the runner or Keel on the bottom , go get some 1/4 or 1/2 aluminum or stainless angle and contour it to the the hull then glass over it . Use the woven mat instead or the hair or chop for the actual fiberglass . Get the longest gloves you can find as the resin is extremely sticky . Prep work is vital to making it last , be sure to sand it good and clean it prior to laying the glass , and you may want to finish hacking off the rest of the ridge so your angle will lay flat once you get it contoured . If aluminum or stainless is not easy to get in your area then use some pvc pipe , just somthing sturdy to help give you your profile back .
