;D I've read it somewhere, but now I can't find it. Where is the best place to stick the turn fin on a rigger (fore-aft)?
Where to stick it...

Here is a quote from somebody, I don't remember who. But it works good.
While there are some guys moving the CG forward from this, Gary Preusse told me a while back that the CG should be at about 80-85% of the "aft-hull." Measure the distance from the trailing edges of the front sponsons to the drive dog and multiply that by .825. The CG should be about that distance forward of the drive dog. The trailing edge of the turn fin should be about 1/2"-3/4" behind the CG with about 60-75% of the fin width ahead of the CG. This should make for a quick turning boat without any nasty handling habits. Almost every set-up I've seen has had the collet or square drive nut right at the CG.
