I bought two books from Jim and they arrived today. Propeller design and tunnel boat design. I read the prop design book this afternoon. Great.

Can I ask about the Hoss design? I know it's similar to old Merc props as I've owned a couple of vintage Merc props, a 3 blade 13 spline stainless and a 2 blade bronze 15 spline. Would this blade shape be considered skewed?
