In Reply to: 3 pt Hydroplane, when to use fins on the bottom? posted by Steve Roffey on November 12, 2002 at 20:55:45:
I built a great 3-point hydro the Jupiter by www.clarkcraft.com I ran my boat for pleasure use and put two smaller fins on the inside of each sponson about where there was supposed to be only one larger one on the left side for racing turning. I took the fins off trying to stop chine-walking (that wasn't the cause) and found that the boat cornered fine with out them for horsing around. email direct if you want more info on my set ups or design. regards, mitchell in CT
