Thought about doing it myself but it looks like a join on the tubes not a puncture. Would it be easy to redo a seal. I cant see where its leaking from at the moment. A freind suggested letting it sink with SWMBO on board to find the leak tho not sure she will go for it.
Spose it depends on where it is on the seal but for the cost of a repair kit it against the cost of a pro repair it may be worth a go. Probably better to get a quote from Polymarine first may not be as much as we think.
