Converted to using a rudder? No need to be, just that if a person IS going 
to use one, what about a decent design - no sliding pedals, support for the 
whole foot, easy position adjustment, no mounting holes through the hull - 
not rocket science to design something like that.

I have supplied drawings to those who have requested them. There are three 
(5?) NZ kayak manufacturers that I can think of straight off that use 
pedals mounted on a platform with a central track/bar. Usually they have a 
series of holes and a sprungloaded pin to position the platform. I use 
webbing and a camlock - micro-adjustment steps. The pedals hinge on the 
platform at the bottom of the pedal or off a fixed piece such that the 
heels brace against a fixed point and the toes move or in my case, the 
hinge is level with the ankle and the whole feet sized pedals move.

All use auto-adjusting rudder lines and have done for quite a number of years.

Rudders all come up and on to the deck, Challenge Plastics and mine pull up 
like a dagger board on a yacht and the blade holder cants over so the 
rudder blade is in the same place as all the others. Difference is the 
blade is locked down to the hull by the pull-up line which goes to the top 
of the blade.

The one exception is the Southern Viking rudder which is mounted on the 
side of the kayak, independantly developed in Australia and here. Both 
designers put it on the port side because the water goes down the plughole 
the other way in the southern hemisphere(???!!!).
