 You can't make the rigging too tight on a Mac because the roof supports
 the mast and there isn't a post under it. You could bend the roof if you
 tried to make the mast too tight.

So when the wind pipes up to force 6 or 7 and the mast starts pumping and 
flexing that cabintop and you're 2000 miles from anywhere... "Oh God, thy 
sea is so big and my boat is so small, and why didn't you bless me with two 
broken legs on the day before I was to set off on this voyage?"
