In the quotes that I've done through Moorings for Power Cats they've "forced" a pre-paid fuel option that varied depending on size. I did a quick check on their website for a 433PC now and it shows as $630 for a week. We've had $805 for a 514PC last year and a 464PC this year. I didn't pursue trying to get that removed but would be interested if you had any success. We used a bit less than half our fuel on the 464PC this past trip and hit up Cooper, Anegada, JVD, Marina Cay and Norman.
