Flat water rudder for fenn xt

I have a carbon xt. It is very stiff and so the tail doesn't deflect upward as much as a glass board. I have paddled in all sorts of conditions including 6 foot surf and it only loses it when I make a mistake. I am also doing a fair bit of flat water racing where the shark fin rudder is way too much.

Does anyone know how I can find a small flat water rudder for the xt. Will other fenn rudders fit, or do I cut down a regular rudder. Who understands rudders and can shape them?

Thanks

If you live in Oz, Latman could sort you out. He built a rudder for a mate's Fenn Elite to replace the shark fin rudder.

If the rudder blade is the same construction as the mako, elite ,swordfish ,etc etc it cannot be reshaped as there is PVC foam core inside and it is very WEAK , I have however moulded our K1 , K2 and ocean ski blades onto the fenn shaft so the same yoke and cables can be used.

Thanks Ian,

Ben Dibley is going to mod a fenn rudder and then re-glass with carbon.

I'll post how it goes.
