If you want to get to shore other than swimming, you need a dinghy unless there is launch service. Doesn't have to be much of a dinghy as long as the waters are calm. Personally like rowing so don't have a motor to propel our Avon Redcrest or 8' sailing dinghy. The Channel Islands are a great place to explore and you'll definitely need a dinghy there.

Our dinghy is our station wagon. We haul water, fuel, provisions, and people too.Not to mention escapting to places to snorkel, and explore. I would like to have a second dinghy that would row, and sail well for fun. The Caribe, and outboard would still be the workhorse.......i2f
