I was looking for some other pictures when I stumbled onto Gustl Spreng’s construction pictures of his KHSD 63 cat from almost 20 years ago as I recall.
I knew it was a variation on CM construction but I had not had chance to study these pictures for some reason.
I looks like he made a series of female stations and then forced the plywood into that shape. It must have also been vacuumed. The results looked excellent. I recall that core was then bagged into the inside, along with triaxial on top?
I cannot find Gustl in the googles, so if anyone helped with this hull construction, you are welcome to fill in.
Amazing results and the mould looks very cool. This is so interesting. It works on a large hull with longer curves. I wonder about smaller hulls.
Plywood is my favourite use of wood in generating shapes. Add that laminating core does away with stringers for a cleaner interior and it seems like a huge up side.
Beautiful hull shapes and great final result.
