“Boat that big probably has a crew as well?”
Yes. I doubt that anyone could charter it sans captain or crew (i.e., bareboat basis). Rough approximatation for captain salary used to be about $1,000 per foot but that may be low given the area and a host of other factors. The entire electronic suite onboard boats these days is pretty complicated and mechanical knowledge required to run them can be daunting, not to mention seamanship considerations.
So an "average" captain makes about five hundred bucks? :=)
