You are interpreting wise words of caution, based on knowledge, testing and experience, as negative comments.
Essentially you are saying the readily available insulating grade of XPS (30 to 50kg/Cu.m) is not suitable for hull panels exposed to water. So you are agreeing with what has already been stated.
I have never stated that XPS is unsuitable for use in a boat. On the contrary, it is a useful bulk filler and stiffener where the surface is no exposed to impact.

Not so long ago Rob made a comment about my "closed little mind", in response to my reluctance to even consider the idea of foam cored hulls at all, much less below the water line...... and dismissing proas, Harry or otherwise, for my use.
