I was looking at my cousins fin set up on his fish and there is about 1/8 inch of toe out. Is this why i cant get the board to work for me? It seems as if the fins would just act as brakes with the drag they create.
Well I will take a shot at this one, please let me know where my reasoning is wrong.
Fins are generally toed in, so I don’t see why toed out fins would work like brakes any more than toed in fins would.
But the affect toed out fins would have would come into play more when your turning. Basically, from what I have been told on this forum, the fin creates lift when the board is on rail, so I am guessing toed out fins would pull the board down in the water more when turning, probably not good. Though maybee it is good because Fishes are generally hard to get on a rail because the tails are so wide.
Have you ridden a fish before that worked for you?
Ahhhh, I ember getting into a shitslinging contest with Catri on this one. He had his FORMULA for setting the fins, 3/4" from the rail on the rear and 1-2/2" from the rail in the front.but, the only problem with this is, the fins pointed AWAY from the nose. The rail got sucked into the wave so gaggingly bad that it was nearly impossible to ride with any result that could be termed fun ( you ever get your trucks on your skateboard backwards)?
an assymetrically foiled fin creates lift - it is a “wing” in the water. two assymetrically foiled fins lift against each other
toe-in (IMHO) acts to neutralize the effect of two fins acting against each other, and to sink the inside rail deeper in a turn, where the inside fin is deeper (in a region of higher pressure and more lift).
Toed out fins would… um… let me think… well the inside fin would try lift the rail, so the board would want to rail turn more… this is not as sharp a turn as the pivot you’d get from toe-in fins. If the template isn’t adapted to rail turns you’d probably bog a bit when trying to turn. It’s conceivable but unlikely that your style might adapt to this, or even prosper with this setup.
…Parachute!
…Toe-out ,naw take a good look at that board again with a measuring device…(what you are seeing (w/o measuring) is a optical illusion).
…back in the 80s…I had someone give me a board because he said it didn’t work for him anymore.
…Come to find out that he had fixed the outboard fins on this thruster after cracking them out at the base.When he repaired/replaced the fins he had actually toed them out, just slightly, due to lack of proper design knowledge.
…Results: I rode it on 2 waves just as it was.F**k,I practically had to swim the board in due to the mass amounts of drag…After I corrected the fins,the board rode great!Herb
