Just noticed, on my new twinzer, both outer fins do not set flush with the board, but cant up 1/8 to 3/16 inch. (Set flush with the board at the front of the fin, but off the deck in the back.) Any ideas about what kind of problems this will cause?
Thanks
Provided they are glassed on properly no problem
Nope, not glass ons, FCS
Blackmountain,
Greater likelyhood of snapping off under load. Can you post a photo of the “condition”? There might be a correction that can be done without involving the board, only the fin.

Okay , now I’ve heard that they’re F.C.S. fins…
do you actually , in fact, mean it’s a fin TAB problem , ie the front tab screws flush into the plug , whereas the back tab has a gap between the bottom of the board and the base of the fin ? [this is different to “fin cant”]
Like Bill , I think I need to see a photo of the “problem” to clarify … [I don’t understand what “off the deck in the back” means , a photo will clarify that better, I think]
cheers !

Quite a lot of turbulence in that particular area of the board anyway. Probably won’t make a huge difference but I’m sure with a little sanding around the tab area they could be convinced to fit correctly.
Having bottom contours like deep concaves all the way out to the rail or a lot of flip/rocker in the tail area at the fins can cause FCS fins to not set flush with the bottom. A good shaper should take this in to consideration when using most fin systems. Some fins systems like Speedfins fins purposely don’t fit flush in the back, thats how they where designed work.
