I don't have an answer, but perhaps people more knowledgable than me will better be able to respond if you post such things as price
, size, payload needs (i.e. are you a pack mule or a camper), and your intentions (live aboard, trailer sailer, cruiser or "holiday'er"), do you want to live aboard it "for good", or just to sail to some nice place and buy a house, not to mention, what your demands are in the creature comfort area?
Most boats can be set up for singlehandling in one way or another, so it is also a question of how much time and energy (and money) you want to spend on that before departure.
Hell, the Paradox trimaran
is 63 feet long and set up for single
hand sailing. Its amas are ORMA 60 amas (from the Fujicolor trimaran)that has been elongated by 3 feet, making them a whopping 63 feet long. Although not a catamaran
, it is for sale
right now at €1,350,000 (that's Euro!). Or you can buy a huge, really nice Gunboat with all amenities for even more, or tie to surfboards together and make a poor mans wharram
Or, there is also a plethora of nice motorboats around - The nicest of them if I had a choice would be Dashew's FPB83 or FPB64 - of course in my opinion.
