If there is any positive lift profile on the front wing, the positive lift will increase as speed increases. A symmetrical wing will rely solely on the angle of attack and will require a positive angle of attack to lift off, this angle will actually prevent the nose dive of the board compared to the asymmetrical foil.
hi Hawaiis, sorry got lost in this explanation
trying to visuallizing what you mean but then all i can think is that both the cambered profile and the symmetrical profile will create lift, in both cases function of angle of attack and speed, that will turn into a pitching moment regardless
can´t really see the advantages of going with a symetrical foil, basically i´m totally confused!
would you mind to explain what you mean but for dummies?
