Right, I've never seen anyone spell out a limit but there is a limit to the stability as the boat gets smaller and at some point a boat can't support 165lbs at the tip top of it's mast without tipping.

The forces don't worry me, because as others have said, the forces on a mast under sail are tremendous, but stability is a concern on smaller boats. And it might seem stable until a wave comes and knocks the boat just off center.

If you consider it a seasaw with 900lbs 3 ft from the hinge on one side and 165lbs 25'(?) on the other it's easy to see that the 900lbs is going to lose.
