Boat Trip to St John

We will be docking in St Thomas from 10-7 one day this coming August. We are very interested in doing a boat excursion to St John for some snorkeling, beach time, and site seeing. A lot of the catamaran/boating excursions we've done in the past usually have rum punch and beer but from what I'm finding on Trip Adviser, I do not see anything similar to this. Not sure if I'm even looking at the correct type of excursions. Does anyone have recommendations for such an excursion to St John?

There are many boats that offer day trips to St John and many hold a maximum of 6 passengers. How many in your group?

6 is what we have in our group. We are looking for a trip that has alcohol included but can't seem to find any.

This ship has open bar, accommodates your port time, and is located near the ships. They offer public and private options.
