In theory maybe and only for a lead-swinger. But if you play around
a little with numbers I bet you will find the rudder must be a monster
to make a useful contribution to righting moment.

Because it will tend to lift off the pintles which have to take the
weight
when the boats hauled? (reversing loads are worse than unidirectional
loads)

Again, a monster of a rudder, in terms of volume this time, is
needed make this a *real* problem.

Actually, I'm picturing a boat at anchor in a chop (as someone mentioned)
with the rudder banging up and down as the water comes and goes. Noise is
BAD.

Why would you want to make it lighter?

Because it is possible.
Because less weight in the ends means less pitching.

Is this that monster rudder we aren't talking about? Where do you stow your
anchor and chain?

Because lighter is faster.

In light airs. In a chop, weight keeps you going. Sail planes carry water
ballest for better speed and range.

Because it is a hobby of mine to tinker with my boat.

In real life it probably doesn't matter much, but then that's the basis
for
any heated discussion.

I'm planning on adding lead ballast to my rudder stock to keep the assembly
firmly on the pintle. (After I trim the bottom half inch of the stock off).
