Finally replaced my PVC tubes in Hypalon. Although to be fair, the nine year old tubes were sound, just the seam on the rear tapered section to the cone was difficult to repair. A lot of messing around later and the fact that all baffles had gone - made up my mind.
Have gone for a complete change in colour scheme. Anthracite grey with grey fendering with grey wear patches. No ropes, trying to keep it as plain as possible.
Work carried out by Ribbit Ltd., in Portchester. Fair price and good workmanship so far - finished next week and hopefully back in the water.
So, if any PVC ribeye owners having same problems, this may be the way to go.
