Energy involved breaking surface tension is hardly ever mentioned but it must have a good deal of effect especially on flat water.Not sure wether it would be beneficial or otherwise ???? Who knows.
There is no trully scientific way of explaining all effects of boardshape or if there is I cant find it ?? Think its why its a mixture of science and art ?? (a black one ?)
Pretty sure a lot of "developments" are just marketing gimmicks but some work ?? Air tubes from F2 was a good one ?? Remember lots of years ago some builder putting round dints all over base of board ?? (Golf ball ???) Think SB have done their fair share too ??? Original Hypersonic ???
Perhaps failed engineer knows ???????????
