Nice work and beautiful pics Steve! She must be well balanced because it looks like her running angle up on plane is almost the same as when she's at the dock! I understand that designing a boat with those transverse steps that can make hard turns without spinning out is quite a challenge! Looks like you put some pretty good height on those aft longitudinal steps, so it sounds like you found a good solution with those big vertical surfaces that must have a good grip on the water! I always thought that adding some more aeration with transverse steps would be the next logical phase in the evolution of the VDH hull, so it's great to see that you're continuing to advance Moesly's ideas! Have you ever built any models to test out those ideas?
I have a good book by British naval architect Uffa Fox, and way back in 1912, by going to transverse steps, they got 55 kts out of a 40' 5.5 ton boat with a pair of very heavy 400 hp engines! Denny
