Cats are popular and rightly so for term charter in the tropics. These are perfect platforms for large groups of people / families desiring a shared vacation. But the size may make little sense for the single handed or couple cruising up north who mostly go out on the water for the week end.
Cats are excellent solutions for some sets of criteria and not so for others. My sense is their success is largely driven by term charter and families who want to go for long term cruising through the tropics. They will not likely overtake monos in the temperate clients, more crowded with limited docking compared to demand.
I have been trying to point to how these statements are incorrect, and reflect only localized observations being stated as absolutes - and I think Smackdaddy has been doing similar by posting videos and blogs of people out cruising on catamarans.
Yes, the charter market has a lot of catamarans. They also have at least equal numbers of monohulls, and most likely greater numbers of monohulls.
There are many, many, many, people cruising on catamarans long term and long distance, and few of them are larger families. Right now, we are in an anchorage with 5 cruising catamarans and 1 monohull. The cruising cats consist of one single hander and four couples. The majority, by far, of cruising catamarans we meet are owned by couples. They are also a better platform for families, but the number of families out cruising in any type of boat is pretty low.
These are real observations from New England throughout the entire Caribbean, South, and Central America. Chesapeake Bay and New England during the summer get many catamarans cruising there, but they leave with the seasons - just as they previously left tropic climates during the summer season. I've already agreed that catamarans are not good solutions for short term seasonal sailing with winter layups. However, New England has already increased dramatically in full-time catamarans in its waters being used in this manner. Nobody said they would become the predominant type of boat there, but I don't see why that topic is even interesting or what point it is trying to make.
