Swallow tail fin placement

General Discussion

Need help with fin placement for a big guy thruster with a swallow tail.

For swallow tail fin placement, should I measure from the butt crack or the tips of the swallow tail ?

The picture attached is the basic outline concept. Thanks in advance for any input.

The tips, for that one, I believe–standard thruster center fin trailing edge is gonna be at about 3.5" or thereabouts ?

Anyone else?

On Swallows.always from the tips,No exceptions…If the board is truly a “big guy” thruster the fin set I use w/ great sucess is 4" up from the tips on the center and 12" on the sides.

Of course Red-X or Lokbox fin systems would give you a lttle more room to play with.Herb

Herb,

Just the answer I was looking for. I’ve had great success with that placement as well, but I was confused as to where I should measure from.

Thanks! -matt

Herb,

your close. That picture is probably 2 or 3 years old. The hint is the dredging pipe at the bottom of the picture.

I know where it is NOW! …My wife’s grandfather, Commander Hardesty(flew Hellcats in the panpacWWII) served his last days in the Navy there.

Vern it is a nice wave and guarded by it’s locals when it’s on !

I heard about the tourist that was killed at the strands last summer,what a waste.
