Any families used St. Thomas Rental Charters?

I posted this in the S. Thomas forum, but thought I would post here in case any families have experience.

We will be in St. Thomas in April on the NCL Gem. I am lookng for a private snorkel charter for my family (6 people, 4 kids 5-14yrs). I found St. Thomas Boat Rental Charter on Trip Advisor and the have great reviews. Their price is similar to all the others, and they offer all the same things, plus a lot more shade than most charters. They operate out of Red Hook, but do offer pickup/drop off at Havensight for an extra $75. For our clan it would definitely be worth it. I think taxi fare for 6 would be similar in price, and it eliminates a whole bunch of headaches. I cannot find anything about them her on CC and thought I would ask if anyone has had experience with them. They work on the honor system, and take credit cards at the dock.
