I'm posting this on behaf of my less internet savvy Dad.
His boat (Trapper 501) is out of the water, going through a minor refit, (new prop, stripping and cleaning the engine, replacing windows, stopcocks and stuff)
My dad went down to it today, and found it was full of water. Not sure where its getting in, the port aft window is out, getting replaced, but thats covered by a tarpaulin. One of the trailers supposts was blocking the outlet for the bilge pump, so thats why it wasnt draining.
Anyway, problem solved, and after about 15 minutes the bilge pump finished. Dad went down the ladders to get the new window, and seen the hull covered in "millions of tiny blisters) about the size of a pinhead, some slightly bigger. This was only on the 'white bit' of the hull, i.e. between the waterline and the gunwhales. There was none of this at all until now, so it has surfaced in the past couple of weeks since we were last down.
Everyone is at a loss as to how this happened. Dad burst one of the larger blisters and there was water behind it. I am lead to believe, that for 'normal' osmosis, the water behind a blister smells vinagary, well these didn't, if thats any help. The boat sails in freshwater now, but was in the sea up until May 2006.
Has anyone any idea whay could have caused this, or how best to fix it? The weird thing is that there is none below the waterline. Although it was flooded inside, it was only flooded up to around the waterline, and not for any significant length of time.
It seems to me like a case of the dreaded lurgy.
