He tested his theories with a paipo-type platform but applied empirical knowledge to hulled fast speed runner boats. I agree that as presently configured one does not make for a thruster-like turning board. Down the line or big-drop-and-go maybe it will be able to demonstrate something. The closest sibling might be some of the Gus Acosta designs, for example:Nels wrote:Nobody has done anything like that at least for prone craft to my knowledge. Waveskate and probably others have carried concave to the point of "pontoon" like features on the rails, the opposite of this. This looks like my kayak too, and that rides waves.
With no science or trial and error behind me...I would be concerned that it wouldn't turn very quickly, very easily, or both, especially with that deep a "hull" (may have to invent an applicable term for that protusion since "hull" is already applied to a type of surfcraft bottom). That said, for all I know maybe it would. Prone craft are ridden very differently from standup boards.
You are charting new territory. I like it.

A few years ago, I designed a surfboard with a nose in the form of a boat to cut the waves of days of strong winds. with a very marked shape in vee in the nose, Inspired by the surfboard https://www.haydenshapes.com/surfboard/ ... elic-germ/ the result was a tremendous disaster, the board was totally unmanageable from nose, throw it away, you could not surf. of this design I have learned that you can not use very marked vee in the nose
Gus Acosta I have simulated the rails of the normal boards, fallen rails and the version that uses hydro hull. I have put the photos of the study in some previous messages.
The result has been that the hydro hul offers more resistance to the advance than the normal rails without providing lift. for what I have simulated the only advantage, calaliza in water of the center of the table, for this conclusion you can use fallen rails or normal rails with a channel in the center
