Check the Admiral catamaran site. they have owners stories of their trips to the Caribbean. Also of butterfly and barnacle site describes their trip. Stop in St. Helena on the way to Brazil. I may see you along the way on my cat.
I am looking for options how to get from Cape Town to Caribbean in January/February 2013. Would you happen to know anyone sailing that way who wouldn't mind taking passengers (helpers)?
Oh sorry, I've just noticed this message is from 2006. No worries then.
May I suggest that you create a post there saying you are looking to get from CT to the Caribbean. If you don't have any joy there, there are several boat builders in CT and many of their boats get delivered to the Caribbean and they all need delivery crew. Give Robertson & Caine and also Voyage Yachts a call and ask who they use to find crew for deliveries.
