weather helm

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.
