Turns out Matt Miller was absolutely right. It was the the 2009 nylon rudder blades. On both blades the foil was somewhat flatted on the starboard side compared with the port sides. We replaced the blades with a new set of beautiful EPO 2's that I purchased at our local Hobie dealer, Tackle Shack. What a difference. After some trial and error sailing in light to medium winds, we set up the boat of with a slight weather helm as Matt suggested in his FAQ on rudder blade setup. We also rebuilt the rudder system with all new parts except the springs. We took the boat out Saturday with 15 to 20+ mph winds. The wind picked up so much we decided to reef the main to the first reefing point and still flew a hull with two men and two girls on board and all this with a light weather rudder on both port and starboard tacks. It's like a new and altogether different boat.If you come to Dunedin, FL and the Dunedin Causeway let me know. It would be nice to sail with you.
