My brother threw this one at me, and I was without an intelligent response. He's got a 2 yr old little girl and an itch to bareboat charter, probably the BVI. Major question is: In general, how old does the wee one need to be before she can be expected to navigate the decks with reasonable safety. Brother is not interested in leaving her with a sitter, and also not interested in confining her belowdecks or keeping a life vest on her while at anchor. Being childless, I couldn't even give a BS answer.
