Hi Sonic
The problem is best overcome on a Maricat by rotating your rudders under the hulls so the corner of the bottom of the leading [forward] edge is about 50mm forward from perpendicular. This will kick them under the hulls.
You can get all the tips for you boat if you look upthe tuning & FAQ link on the Maricat Asociations web page. It spell it out what you can do step by step
