Hi Gary,
<br>
<br>As I visualize it, the board will retain the same Angle of attack as a conventional boad; by canting it in the hull, I suggest we're just allowing the hull to point in the boat's true line of travel, (the net sum of headway plus leeway) reducing hull drag.
<br>
<br>Regards,

<br>PS Wouter, good point about the skirt - - or you could use a shield that slides back'nforth flush with the hull, and tight on the board if you wanted perfection!
