1/2" and 3/4" futures fin box

General Discussion

I am looking for advice on making a Futures fin box shallower than it was designed to be. The way I understand it the 1/2" box is for side fins and the 3/4" is for center fins. To reduce the depth of the finbox I would like to use a 1/2" box for a single center fin on a spoon type board. The board will be very thin at that point; no foam. Which might be stronger, cutting the tang down on a center fin to fit a side (1/2" depth) box or or cutting the bottom out of a center fin box to make it 1/2"?

I realize that whenever you venture out of tried and true methods and especially when you start asking hypothetical questions unpleasant things can result. But sometimes you gotta go there. Any other comments you might wish to make on the advisability of this possibly half baked idea will be humbly considered.

I might be wrong, but I think you have it backwards…the 1/2 inch box is for the center fin, due to the fact that it is further back on the tail, thus thinner. So if you are looking for the center box to be 1/2 inch, all you have to do is order one, no other modifications should be necessarry.

Let me know if that helps, as I may be misunderstanding…

sbv5 is right. The thin one is for the center - smaller bases on the fins with no cant. The deeper ones are for outside where the fins have bigger bases for the built-in cant. The cant is in the fins, all the boxes are straight.
