I am making a 8’2’’ longboard at home and I’m stuck on how far from the tail to put the side fins. It is a thuster, tri-fin, layout. Help!?!?
Oh and the center fin is about 7’’ from the tail. Thanks.

i know there are some good posts on (tri) fin placement for longboards. Just do a search (fin placement longboard). Of course it’s personal preference so you’re not going to find just one answer. Fin placement on any board is pretty subjective (especially a longboard i would think).
Good luck!
13…4…1 3/8 with 1/4 toe.
Back fin set trailing edge at 4
Front fins set trailing edge at 13
1 3/8 side fins off rail
1/4 toe. 3/16 if you want it slightly more gunny.
Toe, 6 degree.
I been working for me, and some of my peeps.

Rear at 4.5 or 5 up from tail
rail fins 8 inches further up
the more you spread them fore-aft, the stiffer it gets
and the less thrust you get
rail fins 1 1/8 inboard from rail
toed 1/4 canted 6 deg
but if there is vee reduce cant up to 2 deg, and increase it for concave

A couple of good set-ups here doyle! I would suggest that you put
in a big box for the center fin tho and give the board a bit of
adjustability. Set it a 4", 5" or whatever you choose for the thruster set.
Also, set the sides at 7 degrees cant and make sure that you are
2" off the nose. Do not go off of a standard toe measure. Also make
sure that the stringer is straight! If you go off the nose, you will
cancel out any curve in the stringer nose to tail. I have
seen a lot of curved stringers since Clark RIP. some not so bad, some ??? WTF....
I never waver from 7 degrees cant even with panel vee in
these situations. There are certain things that you need to keep constant
to decide what works best with your designs. Toe & cant are two of these
variables that you can keep constant and work on moving your placement
fore & aft. Just sayin.........
Does your surfer turn hard off his back foot? Then reduce the vee.
Is he a front foot guy? Do a 1/8" vee (each side) and he will order another!!!
Fin layout and rails in the tail area are another area that can make a
magic board or a dog. Try to keep it simple if you are only doing a one
off. Just my 2C........
