Anyone made purchase of this fin? would appreciate if i can get mounting hole spacing measurements.

I need to determine if this fin fits my hydro pictured below. Many thanks!

I used the Virginia Craftsman turnfin for that hull (Phil Thomas SS 21) verygood fin. That hull and turnfin has a 1" bolt hole spacing. The UL1 has a shorter .750" spacing. That turnfin you mention can be modified to fit by elongating one mounting hole. Try to mount turnfin as far forward as possible.

that really helps. thanks detox. one more thing when you said 'mount fin as far forward as possible' . Could you maybe take a picture probaly measured with a measuring tape of your existing fin to show how far forward thanks again.
