Hello, can somebody advise me how to repair cracks on RS Feva in the hool? I bought the dinghy in the authumn last year and I found it under patches which were glued on it. See encloesed photos please. I woud like to know if it is comon on Feva and what is the best way to fix it. Mend it? Weld it? Or glue it the same way as it was done before?
Thans a lot for any help. Tomas

Thermoplastic can be welded but I've never heard of any dinghy sailors who have attempted  it, probably requires skill, experience, the right kit and welding rods to be successful.

RS do sell a glue which they claim is structural for polypropylene boats including the Feva.......I have no experience of using it.

I used to weld plastic boats back together. If the plastic has worn thin, it simply melts away unless you are magic in some way. G flex epoxy glue may be your friend in this case.

I know of several dinghy sailors and kayakers who have successfully welded plastic hulls so it's certainly possible but, as Rupert says it may be tricky. I do know from years ago that some kayaks could not be welded as they were moulded in cross linked PP which is a thermo-setting plastic (as opposed to thermoplastic). Anything less than 20-30 years old will be linear Poly-Propelene which is a thermoplastic and relatively easy to weld. If you're not confident then it shouldn't be too expensive to take it to a specialist with plastic welding expertise.

PP is notoriously difficult to get anything to bond to so personally I'd be reluctant to trust even special epoxies to do the job but, TBF, I haven't any experience of modern adhesives in this context so consult an expert.
