Hi All
We bought our Princess 435 in August 2013 which had been previously coppercoated. As the boat was displayed ashore the coppercoat could be inspected and we were advised by the broker it was about 6 years old but there was no paperwork to substantiate the age. The surveyor thought the coppercoat was older than this but would not make a commitment. Anyway we bought the boat and abraded the hull before re floating. Due to various issues with the boat since purchase we systematically cleaned and abraded the hull each time there was a lift out but noticed the fouling was getting heavier every time until the autumn of 2015 it was obvious the coppercoat was not working effectively and a solution was required. One of the issues was thought to be the tidal mooring we had and various comments on the internet inferred that soft silt was not conducive for an effective coppercoat system so the decision was taken to revert to normal antifoul paint. In March 2016 we coated the hull with Jotun Vinyguard Silvergrey as a tie coat and then applied 3 coats of Jotun Seaforce 90. We have just lifted the boat again for the periodic anode inspection and have now seen that the seaforce 90 has disappeared in the areas where the boat sits in the mud, just leaving the antifoul in good condition along the water line. There also appears to be white marks on the hull which the pressure washer finds difficult to budge which we think are patches of the tie coat that have stuck to the coppercoat. The boatyard we are in have stated a 2 part epoxy primer like Gelshield 200 must be used over coppercoat and then antifouled over the epoxy within 24 hours to make sure the antifoul sticks in position.
Has anybody else had issues similar to this as some previous posts have intimated the tie coat and seaforce 90 should have worked OK but the other posts might not be moored on a tidal mud berth. Any advice would be greatly appreciated.
