Two small boats came through the locks while we were there. One was just over 50m in length while the other was much smaller and just under 50m in length. Both of these boats looked like they might be quite comfortable. They were also both flagged in the Caribbean. A quick Google search on each showed that they were available for charter. Both seemed to have plenty of people on board but they looked like they might have been the crew rather than the guests as they seemed all business as they handled these tiny boats through the lock. If I decide to get a boat at some point, I might be tempted by either of these. I do prefer one over the other but I suppose I could make do with the less preferable one if the price were right.
