Actually, it's more than theory. Keel-stepped masts are - in fact -
stronger than deck-stepped. But, as Peter points out, the deficiency can be
made up by by beefing up the standing rigging or the mast itself. I've
owned my boat for almost 20 years without a leak from the partners, but I
suppose the "inevitable problem" will happen some day [grin]. And, like
99.9% of the sailors out there, I've never rolled - nor do I expect to - so
I have yet to realize gaping holes in my cabin. I do have a friend who
survived three days in a liferaft after his boat rolled and sank within 30
seconds - deck-stepped mast and all. Stuff happens out there.
From my perspective, there are advantages and disadvantages to both. Most
sailors have very strong opinions (!) but either can and will work
satisfactorily on a cruising sailboat. Get the boat you love, and don't
look back.
