Genoa tracks h26.5
I mounted mine next to the cabin top and there is an aluminum plate under the fiberglass so you can screw them down, you shouldn't have to thru bolt them, i also had a 170 genoa also...made a big difference in light air because the bulb wing keel has to have water flow over it, otherwise it is just drag. The boats best point of sail is downwind, i actually beat j30's and hobie 33's off the wind corrected and a j24 can't sail with you downwind unless they heat it up and hit their jybe angles correctly. good luck
