Hey all, I can’t get fin boxes where I live…so what would be a good placement for tri fin? I’m ready for a 7’6’’ and I want to make 6’6’’ as well also a fun shape 6’0 for visitors. Thanks!!
i am assuming by tri fin you mean a thruster and not a 2+1 or any other 3 fin setup.
It is kinda vague as to what type of board these are and what type of waves these would be ridden in. Both of these factors would cause fin placement to change. here are some broad ranges:
Center fin: 2 7/8"- 4" or so, rail fins are about 1- 1.25" in. from the rail, 10.5-12" up from the tail, 2-9 degrees cant. Tow in is angled anywhere from 1-7" off the nose tip.
specifics would help me to understand where actual placements should be.
