I've heard of meetings happening on trains, planes, and automobiles (well, buses, anyway), but I hadn't thought of using a boat as a meeting venue. Not a cruise ship, but a local charter boat, as detailed in this article from the Palm Beach Post. From the article:
MacPhail estimates that about one-third of his charter customers are companies looking to conduct business on the water, from product launches to year-end wrap-ups.
"That was nonexistent five years ago," he said.
I'd love to try this for one of our weekly editorial meetings, but maybe I'll wait until summer to suggest it. Somehow, I think Boston is a little different than Palm Beach in January.
