How do you rig a Wave so that it turns to the wind when you let go of the tiller bar? I've fiddled with mast placement and all positions have at least some leeward bias. Mast back is stronger, mast forward it still turns slightly leeward. I try to avoid heavy wind as I always sail solo, but it would be reassuring to have the boat turn windward if I got dumped off. Any suggestions? Thanks. |

I am very interested in this too and have not been able to accomplish it. I have my mast raked back with a 10-hole adjuster - I'm in hole 9 (almost the top). I tried it again at the weekend; I uncleated the sheet and let go of the tiller, and the boat sails perfectly straight. |

Rudder rake also affects the helm. This info comes from Hobie: RUDDER RAKE Excessive weather helm (when you must pull hard on the hiking stick to keep the boat from turning towards the wind) can be corrected by cocking the rudders farther (forward) under the boat. If you have too much lee helm (very little pull on the hiking stick, with the boat tending to turn away from the wind), this is corrected by unscrewing the adjustment and cocking the rudders back (aft). The amount of rudder rake needed depends on how far back the mast is raked and how much weight is being carried. The biggest problem with rudder adjustment is when a skipper changes the blade adjustment screw without reseating the cam plate in the upper casting. Even a very minor adjustment to the rudder could cause the cam to lock partially rotated, dramatically reducing the kick-up resistance. That means every time you make a blade rake adjustment, you must also reseat the plate AFTER you have finished adjusting the blade rake.There are three very important adjustments that should be made to the rudder assembly. 1. The rudder rake screw which adjusts blade angle. 2. The cam plate bolt which holds the blade forward. 3. The cam tension screw which adjusts kick-up tension. When system adjustments are made improperly, the system won’t work right. You must follow these steps in order! 1. Lift the rudder arm to unlock the assembly. 2. Using an allen wrench, adjust the rudder rake screw to give the desired rudder blade angle (rake). 3. Make sure that the blade is seated forward against the adjustment screw, loosen the cam plate bolt and lock down the assembly. Slide the plate back a little and then forward as far as it will go up into the cam. Retighten the bolt with a 1/2" socket. 4. Adjust the kick-up tension screw with a screw driver. You can calibrate the tension with a fish scale by making a loop of rope and putting it on the rudder blade about 24" down from the front bolt hole. Hook the scale to the loop and pull. Factory kick-up tension is set between 18-22 pounds |

Thanks. Yes, rudder rake is what I think needs to be adjusted, but I don't know how to do it with the ez-loc rudders. |

I don't think you can adjust the EZ Loc rudders. Jim |
