Re: BVI chart/nav app
The typical dinghy on charters is a hard bottom inflatable, which weighs about 150 lbs. Add a 2-stroke, 8 hp motor and gas and you are pushing 250 lbs. You'd need a winch to haul this aboard and then you'd risk cosmetic damage to the foredeck.
It isn't worth the hassle and, besides, you aren't sailing that far. Best advice is to relax and tow it.
