Here’s a little breakdown of our trip last week. I keep track of this kind of thing so that when we invite newbies to go with us, we can give them a ballpark number of what the trip is going to cost (aside from the charter cost).

Taxi from STT to Ferry dock: $40 with kevin (incl tip)
Ferry St. Thomas to Roadtown: Fast Ferry $99 for 2 ($70 ticket + $20 port tax + $9 bags). Tipped bag guy $5
Ferry from Roadtown to St. Thomas: Native Son $79 for 2 ($70 ticket + $9 bags). Paid $40 departure tax separately ($20 pp). Tipped bag guy $5.
Rental Car on Anegada: $75
Fuel: last 2 trips on a cat we averaged between $68-$84 in fuel for the week. This trip on a 48’ power yacht we used $498 in fuel.
Alcoholic drinks ashore: Averaged out to $10/drink (includes 20% tip). We had cocktails pretty much at every island - $40 per island (no beer, all mixed drinks)
Meals out: Cow Wreck lunch for 2 w/6 drinks + tip = $90 Wonky Dog: dinner for 2 w/4 drinks + tip = $133 Saba Rock: dinner for 2 w/4 drinks + tip = $112
Groceries: Provisioning with Riteway + cooler of meats from home = $500 total This fed 6 people for 7 days (excepting the meals out mentioned above)
Liquor: That’s easy to figure out from the list at Caribbean Cellars or Bobby’s. Everyone on our boat paid for their specific alcohol except we shared the cost of the margarita fixings. You can pick up more booze almost everywhere you go – I wouldn’t over provision this. One couple literally donated a case of beer at the end of the trip to the charter company.
