Maybe, or maybe not. You shouldn't make blanket statements like that, because different boats react very difference to changes in the sail plan.
My present boat, for example, is entirely insensitive to fore and aft balance of the sail plan. Weather helm
is a linear function of heel angle. I can sail with jib alone, main alone, or any combination, and it makes no difference at all to helm
balance, unless I'm heeling more than 20 degrees.
If the OP removed his mizzen, I would bet dollars to doughnuts that he will sail FASTER, not slower, at least upwind, as a considerable amount of drag is eliminated, and the mizzen on a ketch generally produces usable drive only on a reach.
However, I would never remove the mizzen of a ketch. The value of the mizzen for providing more sail plan options, and as a place to mount stuff conveniently, is just too great. In my opinion, the ketch rig is the ideal rig for a motor
sailer, which will not be sailed upwind anyway.
I have spent a great deal of money
and effort making my boat capable of sailing long distances upwind. I don't regret it, because I love to sail, and I've succeeded -- just got back from sailing 1500 miles against prevailing winds, and had 1/3 tank of fuel
left when I arrived and bought no fuel
on the way. But I have to say that it is much easier and much cheaper to get this capability with engine
power than with sails
. All modern cruising boats, including even mine (with her tall mast, carbon laminate sails, bulb keel
, etc.), are used mostly or at least very often as motor sailers. So the ketch rigged and honest motor sailer is actually better suited to the needs of average cruisers, I think, than cruising boats pretending to be pure sailboats, but not actually used that way.
