This has been an ongoing project for me. Boat has a CMB 91 hr Mac 15 cc pipe.

Boat kept tripping in rough water. Tried 3 different turn fins. Found the best combo was to run with a Mike Hughes turn fin

an install a antitrip on the port sponson. Antitrip is .50" x .50" tapered to the front.

Boat is running great. started with a H-48 for testing. Went to a 1667 7.0 cup and boat was still getting on pipe easily.

Tried a V967/3 and the boat was a rocket but kept pulling to the right. Should I stay with the 1667 and shorten pipe?

Pipe is at 11.50".
