: G'day Bill,
: I took an each way bet and modified the rake to somewhere between
: the original and an elliptical surf rudder. Will bevawhile
: before I can comment on its effectiveness and I won,t have
: anything to compare it against as I expect that the hard chined
: boat will feel very different to what I am used to in a high
: performance ski.
: The difference was dramatic when I fitted the 9" surf rudder
: to my ski. Some have commented that doing so will make a tippy
: craft even more tippy. I don't think tippy is the correct term.
: there is an increase in turning response that can throw you off
: balance until you get used to it but the boat isn't "
: tippier".
: Hope to have a pax update before too long as our Summer Holidays
: are upon us.
: Cheers
: An interesting bit of info that I have picked up on the subject is
: that the Supermarine Spitfire has a wing much like an elliptical
: surf rudder.

Hi Craig,

Yep the Spit's got a double elliptical wing, it's that shape from the top and from the front/rear, ideal wing platform for a subsonic wing.
