I assumed from the beginning when you asked about the largest trailerable you really werent interested in a rehash of what a great boat the Mac is, thus my comment about hijacking the thread. It's obvious that a Mac won't do.
That being said, your expectations seem unrealisitic.
You want a world cruiser, but you want to be able to trailer and launch it yourself. If youre world cruising, exactly how many times per year, or even in the entire lifetime of the boat (or your own lifetime) will you be trailering and launching it from a fixed location? How frequently would you propose trailering "across the continent"? If you've got the time and money to be world cruising, saving money by trailering your world cruiser across the country is a concept that hurts my head.
The 32RK has a 106 beam and weighs 8K lbs empty, 10-12K lbs equipped for world cruising. Special permits, and somethng approaching $35K plus maintenance and operating expenses in a trailer and dedicated tow vehicle. But this is too small, so scale the RK to 42. That gives a boat with a beam of nearly 14 and a weight of perhaps 18,000 lbs empty. Bump the above cost of the trailer and tow to $50K, and youll need a lot more than special permits to move this any further than out of the marina parking lot. Anybody have a clue what over the road insurance might be on a $200,000, 42 foot boat, and $50,000 trailer and tow vehicle?
You certainly won't be rigging and launching a 42', 18,000 lb boat from the local municipal ramp.
The logic of lving aboard a boat to save the cost of heating, air conditioning, and taxes escapes me.
Wherever you intend to live, be it boat or house, you either need heating and A/C or you dont based on the climatic conditions. In fact, fuel, power, water, maintenance, everything tends to be considerably more expensive when purchased in a marine environment. There are probably not two or three locations in the world where living on the hard in a boat with no heating or A/C would be something a reasonable person would want to do.
You cant avoid the real cost of property taxes by living on a boat any more than you can avoid them by renting a home. Except when actually on the water or trailering, you will be paying the indirect equivalent of property taxes no matter where you keep your boat.
If you intend to skip the necessity for heating and A/C and paying taxes by staying on the water, go back to question one: why do you need a trailerable?
