Thanks Jimboat

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?

Jim's books should really be mandatory reading for any high-performance boating enthusiast. I recently read the latest version of the Secrets Of Tunnel Boat Design and reviewed it here (https://www.screamandfly.com/content.php?531-Secrets-Of-Tunnel-Boat-Design-Second-Edition-Now-Available). I'm also going to have a comprehensive review here of the most recent version of the Tunnel Boat Design Program (https://www.aeromarineresearch.com/tbdp6.html).
