Traditionally the turn fin is mounted on the right side sponson transom, assuming your running clockwise.

show us a pic if possible, and let us know which make/size rigger you have, and if you intend to race or just run for fun....</p>

Usually 1" behind the CG.

Ron the 1 inch is that the leading edge of the fin or is that the backof the fin

Thanks

1" behind the CG ron? sure bout that?

OK, I'm getting back into 'riggers after being out of them for a while (see the JAE .12 thread) so I was told 1" from the front of the turn fin to the CG. With the JAE fortunately I have the option of 3 positions to move it around to find which setting I like.

well your first post said 1" behind the CG it should be in front of the CG

wow i just went and measurd it and i have it at 3.5 inches that may explain why it has a mind of its own and turns way to tight

thanks for the help guys

does this 1 inch apply to hydros as well

Thanks Mike as I wasn't exactly sure and started confusing myself! I retyped that I don't know how many times before hitting the OK button as it didn't sound right to me either.

no problem ron

basically yes

think like this the boat balances on the cg what ever it may be for the boat its different with all of them, the turn fin is a pivot point when turning if im remembering correctly if its to far forward youll have wide turns to far back youll have super short quick turns or even spin outs and be squirmy which I see you figured out place the Trailing edge forward of the CG a little and tune it from there the 1" may be to far forward but again thats where trial and error come into play you may try and find someone that has a rigger like what ever you have and ask what they run at, that would give you a starting point for yours and make tuning easier
