: That might just work for the sail area he is going to carry, Bill. There are,
: still, some issues that would need to be sorted to make it a really good
: rudder for sailing a boat that is, potentially, this heavy and fast when
: loaded and fully hooked-up.

: I'd add a pair of bent, right angle aluminum plates (riveted or lightly
: bolted/sheet metal screwed) on the underside of the steering yoke that
: took the side support for the rudder right on down to the waterline.

: I'd still replace the blade core with slightly heavier gauge 316 stainless
: steel and I'd further add the above mentioned wooden side plates to shape
: the blade to a foil section for better lift and less drag.

: The blade profile and chord is OK, but I'd prefer to see the angularity
: shaped into a smoother set of curves with better tip shape for flow
: retention.

Hi Chris,

The feathercraft rudders have a rep of being pretty stought already. I don't much like the mount, but I suspect it'll work fine. It's also I think a flat blade which I also don't much like, but you can learn to live with it. It's also pre-built and thus a whole heck of alot easier than designing and building one :)
