If you have a raked rudderpost as on my old Wharram cat. a bouyant rudder
blade causes the rudder to float up towards one side or the other, not a big
problem in normal conditions, but in very light wind it could make things
difficult for the selfsteering, also caused an annoying rattling noise,
mainly noticeable at anchor- especially in a bit of a chop.

Because you'll have to add more lead below the waterline to keep the weedy
side of the boat down?
