Yes?



Rake the mast for speed/power, adjust the rudders for helm until almost neutral and proceed to rip the rudders off the gudgeons or break the rudderblades becose the load was too high. Tried and tested.. Or build the rudder system/transom bulletproof, rake the mast enough aft, overload the rudders so they ventilate and loose control. Tried and tested..
Raking the mast aft will increase loads on the rudders, and by raking the rudderblades forward you will only remove the symptoms. Boat will still not be in balance. With balanced rudders, you will not feel the imbalance as weather helm, but you can see it when looking at the rudderstocks wether the boat tracks straight or if you need to correct it by sailing with a constant rudder angle. 1-2 deg of weather helm is OK, and helps you go to windward, but not more (perhaps the H16 can use more with an advantage, as the water comes off the asymmetric hulls in a different way than symmetric hulls. I dont know for sure). Overdo mast rake and bad things happen becouse the boat is not in balance, and you will be slower than the rest becouse of the extra drag from the rudders.
