Hi Kipper, i was the previous owner of 957 who posted the request for advice about the hull blistering. THis was fairly localised around the starboard bow and was basically down to me failing to remove the hatch covers after a sail, combined with a couple of days of v.hot weather. Moisture got between the wood and the paint and hey presto....blistering. I repaired it by stripping it back to bare wood, allowing it to dry thoroughly then using an 'International paints' 1 Pack finish. SLightly different colour to the the rest of the hull but it seemed to do the job!
Otherwise the boat was great, quick other than against the new epoxies and an excellent intro to the class. If you need any further info then pm me.
Cheers
Andy
