"this" is the link, VDS Forma 37ft steel yacht.

Re: Sigma 36 Is there some apples and oranges going on. A cruiser racer might well have a more lightly built hull and greater ballast. That would be good design intended for its purpose. Whereas a more cruiser oriented yacht could with reason be built with a heavier layup to withstand the...

Many years ago I went gliding with a a winch launch. Shear pins cost money and so to save a little a wire nail with the same strength was substituted. This was fine in theory but the quality control of nails is not consistent and every now and then we had a soft nail, the strop would part and...
