I am also "too big" for my Wave, and for the life of me can't understand how a tiller extension could hurt.

Before I bought my boat, I sailed a 2011 boat at Madcatter, and all I heard going upwind was the gurgling of the rudders because the boat was so poorly balanced with my weight so far back (I was sitting as far forward as I could and still reach the tiller).

I now own a 2009 Wave, but I also bought an older boat to get the old rudder system, selling it with the EZ Locks from the new boat.

This seems silly for a class that wants to grow.
