The ship is gorgeous - beautiful old wood, gleaming brass. If you're into classic old sailboats you'll love it. The captain is awesome, although I think he's taking vacation time sometime in the near future. If Casey is there, please tell him Peggy (one of Chris Cargen's girls) said hello. (Chris is the husband of my good friend and was brave enough to do this sail with three women.)
I've done the Blackbeard and you'll have way more in the way of conveniences. (Your own toilet and shower for one thing) The berths are small, but ample. You DON'T have to trip over your luggage, which is good.
I don't know how old you are, but the crowd is generally older than you'll find on a liveaboard dive boat. They're usually a little off-beat, but if you're like me, you like that.
I did dive on the last trip, although no one else in my party of four was a diver. This is definitely not a dive boat. They have shore excursions just like a cruise ship. If you're interested in something, you sign up and they arrange for a dive operator to take you. There were probably only about six or seven divers on the Polynesia last year. One day, there were only two of us who wanted to dive and they cancelled the excursion because not enough people were interested. That sucked.
They do something that is irritating to me....silly games and costume nights, etc. If you like that sort of thing, you'll be pleased. If not, you really don't have to participate, but the pressure is there to do so. Take a costume of some sort because many of the passengers are repeat customers and are WAY prepared, although I believe the tradition started out as a "find whatever you can and make a costume out of it" (resulting in many toga bedsheet outfits).
They didn't stay in port long, although, like I said, I haven't done the ABC itinerary. On mine, we had more ground to cover, so maybe you will have more down time. We never stayed more than a day and a half anywhere.
Do take advantage of the shore excursions like guided nature hikes and village walks (bar tours actually). They're fun and educational.
As long as you go with the "island" mentality that you always need in the Carribbean, you should have fun on the Windjammer. No worries.
If you want to know anything specifically, don't hesitate to ask.
