Hammock chair
About 15 years ago, my wife and I were honeymooning on Virgin Gorda. We were at the crawl and a 35 footer or so came in and dropped the lunch hook. After awhile they rigged a hammock chair to the boom, dropped the lifelines and swung a young man over the side, letting him down into the water. They placed him in an inflatable pool float like thing to let him check out the reef etc. As I recall it was clear plastic and acted like a lens, or a glass bottom boat.I never got close enough to see how the tackle was rigged on the boat, but my guess is that the young man wieghed about 140 or so.It seemed like a great idea. I've seen similar hammock chairs for sale in homegood stores and also hiking stores. Oh yeah, my memory is faded, but I think he was attached to the boom somewhere near 80% out from the mast, about a body width outside the traveler. He used the mainsheet apparatus as a handle.Just my $.02.Geof
