Most of my info on the Skuttle is second hand, but they do not have a good reputaion amongst the pilots of their direct competition. Nantucket Shuttle only flies HYA-ACK-HYA. All trips are out and backs. There is no contract. I have never seen a shuttle FO. I have seen 10 passengers get off their airplane. They pay double to triple what Island and Cape Air do for the same flying. They charge passengers much less(I think its about 25% off). They never miss a flight for maintainance. They never have a deferred autopilot. The conditions are never too poor for them to go on time. One ex-Cape air pilot (who was bat-s*!t crazy) flew there for a while, when he left he said "(Shuttle) takes too many chances." They've been known to fly at night with their lights off, "So you can't see us."
The money is tempting, but there is a good reason they pay so much more than the others doing the same thing with the same planes at the same time.
