Hydrovane Rudder Dimensions

[Jdiamond]

Hi I have had the misfortune of someone taking the selfsteering rudder off my yacht while it was in the marina, I have got a hydrovane set up so I a going to make a new one out of marine ply with glass over top. All I need are the dimensions of the thing,
if anyone has one and wouldnt mind messuring it would be a great help or if you could direct me to a site with them would be just as cool.

Thanks very much.

The Hydrovane rudder is 93cmx32cm

Make it bigger than standard. I find my Hydrovane seriously underpowered. It can't cope with the asymmetric on a 37' cruising boat.
