Hi. I recently rented an O'Day 20 with my dad after selling a slightly newer one which we owned for 16 years. The one we rented was a centerboard model, and it did something that was quite odd and potentially dangerous: In the heavy winds that were on Lake George that day which was sinilar to ocean conditions, the boat had such severe weather helm, THE BOAT LITERALLY AND UNCONTROLLABLY TACKED ITSELF. That's right. The boat uncontrollably TACKED ITSELF. My dad, who sailed around the world in the 70's and had done a great deal of sailing in his life, said that our O'Day 28, Telperion, had allot of weather helm, but he said that he had never seen Telperion, or any other boat do that before. We suspect that the probelem was because the keel drew allot more water than the rudder when the centerboard is down. This may not have happened to us with Telperion because we just had the shoal draft keel with no centerboard. SO: I WAS WONDERING IF ANYBODY ELSE HAS HAS HAD THIS PROBELEM WITH THE O'DAY 28.
