I don't mean to rain on your parade, Leopard Star, but if you can find someone who owns an expensive catamaran
and who would be willing to do the swap, he / she would more than likely not
be willing to let you cruise
it in the Caribbean
after about the first of June, depending on his / her insurance
policy. Most insurance
companies consider June 1 the beginning of hurricane
season, and coverage will not be in force if the vessel the policy is written on is inside the hurricane
box (about 11.5* N. latitude to about 35* N. latitude after the date the policy defines as the beginning of hurricane season.
Typically, cruisers head
north up the US east coast
at that time of year, both for that reason and to find cooler climes. If you could see yourselves doing likewise, it could be a great adventure.
Good luck in your search.
