“On the exterior of the hull below the waterline I removed random areas of anti-fouling paint, I inspected the surface and metered for moisture absorption. It is apparent that an amateur osmosis treated [sic] has been attempted, a proper osmosis treatment entails planing the gelcoat off completely below the waterline, cleaning and drying the laminate and then recoating with a suitable solvent free epoxy paint system. In this case it seems that just the visible blisters were sanded off rather than removing all the gelcoat, which is almost bound to lead to a recurrence of the problems. There are now blisters in the paint and in the gelcoat under the paint, in many cases the filler is cracked or missing. High levels of moisture register on each of the fourteen areas checked. Moisture absorption will weaken the laminate and shorten the life of a fibreglass hull and so it is imperative that a full osmosis treatment iscarried out, to maximise the lifespan of the vessel this should be done in the next two years. . . . the hull and superstructure remain sound. The only significant concern is the moisture absorption in the gelcoat below the waterline, a full osmosis treatment should be carried out in the next two years in order to maximise the vessels lifespan”
“It was apparent that not all the original gelcoat had been removed, at least 70% of the surface still has either gelcoat or filler remaining on it.”
“As you have not to date replied to my email regarding this issue I can only assume that you are not interested in correcting this problem.”
“As you can see from the photos I forwarded, sheets of paint are now falling off the hull and it is obvious its not the chocking up of Rhapsody at Marine Performances Yard that has caused this problem as you suggested in your recent letter. Other marine engineers have commented on the state of my hull and two have suggested the cause of the paint failure is possible amine sweating??? Whatever the cause of the paint failure is, I can only hold Sirius responsible, after all they applied the paint and its now important I act to protect the hull as soon as possible.”
“I carried out an amine blush test on the flake you sent through and the result was a positive identification of an amine blush. As you know, if the coating develops an amine blush on the surface during curing, which is not subsequently removed, this will inhibit the next coat from adhering to the surface.”
“In order to rectify the defective paint, we needed to strip the Vessel’s paint back to the GRP to ensure the new paint has a reliable bond throughout the hull. It would not have been possible to just replace the top coats of paint.”
“The generally agreed route to osmosis treatment nowadays is fully dependent on the areas affected. If widespread and deep enough to reach the matting; A full strip of Gelcoat, rinsing, drying, application of biaxial matting and then rebuilding the protection layers to antifoul is recommended throughout the hull. If only small areas or not yet deep into the matting, then smaller patches can be treated as above. This is a recent change in industry thinking.”
“The quote from Cardiff Marine services seems completely suitable and fair for the work undertaken.”
“Paragraph 38(a) to (n) are denied, save in so far that the Defendant admits that the final coat of Gel Shield 200 and the antifouling paint failed to adhere to the previous coats of Gel Shield Plus. The Defendant’s negligence is admitted but limited to this extent.”
“I have actually just seen a copy of the report by Mike Godding. Should you now wish to instruct us to carry out further gelcoat removal in order to speed up the drying time then we are happy to do this. . . . The costs of this is . . . so could range from£468 to£780 . . . [the vessel] is now under the covered blasting canopy at the rear of the yard awaiting your further instructions.”
“Preferably a rebuttal of Kate Moss’s email. If this is not possible the provenance of the paint sample and its relationship to “Rhapsody” together with Kate Moss’s technical qualifications to make her assessment. Or admission that there is no provenance history in place for the paint sample. If possible expert opinion on the effect of Gel Shield 200 by returning “Rhapsody” to the water without the damaged top layer of gel shield being repaired.”
