A group of us chartered two sailboats in the BVIs several years ago. There were 15 of us and I think we brought five blenders. We couldn't get the boats to power the blenders so we ended up making margaritas in some unusual places. A grocery store worker on Virgin Gorda let us use their outlets; we used the outlets in some marina restrooms; and we did "borrow" some shore power on the docks once in a while. We could never make them in an anchorage though. I do have a handcrank blender I bought a Restoration Hardware for our own boat, but it's kind of a pain.
Have fun.
I love your resourcefulness! To blend is to live. We're on a powerboat with a generator, so it won't be a problem - boat drinks will be available 24/7.
