This is my opinion only. By the time you get aboard the boat you will find everyone pretty tired and very hungry if traveling from the US in the same day. Head to the Moorings pool, order a painkiller, ask for the bar menu, take a dip in the pool and eat.
If you are already there or have more stamina then my group your dinghy should be attached to the bow of the boat. You can run across the harbor to the downtown area where there are lots of options.
