Swapping rudders

I'd like to change the rudder in my red 7 to an elliptical. Does anyone know if the THINK, EOS or CARBONOLOGY rudders fit?

All the boats have different length rudder shafts, so you'll need to order a new rudder. Give Hein a shout at Carbonology Sport. He used to manufacture the Red7, so he'll have the dimensions.

Peter,
if you have no joy with Hein I might be able to help. Drop me an email.

Thanks for the tip.
I emailed Hein and he can do it for me

Cheers.
Peter
