I have just seen your post regarding alleged hull delamination
on an HR37 and I wonder if in fact the problem is water
in the foam core, which seems much more likely. There is a current
post on the HROA site about water
in HR42 hulls and I have had serious problems with my 1999 HR34. I discovered this by chance when my boat was 5 years old. Water had got in at the site of a badly installed galley
sink skin fitting and spread through a large part of the core. I was just in time to prevent a similar serious problem at the heads skin fittings on the other side of the hull. During the past five years I have spent much time and money
drying the hull out as much as possible, to the point where I would now feel reasonably confident in putting the boat on the market. It has been a very sad and stressful experience.
Magnus Rassy was not helpful. He said that all boats are wet and I should give up and go sailing. But he managed to lean on a UK yachting magazine and prevent them publishing an article.
Germanischer Lloyd agreed there was a serious defect in the construction of my boat but regretted there was nothing they could do.
You would have to work very hard to persuade me to buy another HR or indeed any other boat with a cored hull below the waterline.
Oh, and I have another problem with water in the foam core of the rudder
, where more poor detailing has allowed it to get in. At least one other 34 has had this defect.
Best of luck with your research
. I would be pleased to hear what you learn.
