Couple of questions for you lot...
1. If a 20 year old GRP vessel got a clean bill of health from a surveyor in terms of no signs of whicking, blistering or de-lamination, and a low moisture meter reading, 3 years ago, and spent the subsequent time in the water (some sea, and 1 month fresh) apart from 6 months on the hard (so a total of 29 months in sea water and 1 month in fresh water).... would you think it could have started to develop worrying osmosis related issues by now?
2. Same vessel, currently in the water at the end of the summer season in the water, with 6 month old AF and some green growth just starting to come. If it was hoisted for a few hours, and then jetwashed, so a surveyor could stick a moisture meter on it (after scraping back the AF here and there) - would that yield useful information? Or would the fact that the hull will blatantly be really quite damp mean this would be a near pointless exercise?
Thank you!
