Is fuel included in the price?
On effectively every trip listed here, yes. Fuel is built into the price and you should not be asked for a fuel surcharge at the dock.
Fuel is the largest single cost in running an offshore boat, and it is the main reason a twelve-hour bluewater day costs several times what a four-hour inshore morning does. It is priced in from the start.
If a captain asks you for extra money for fuel on the day, do not pay it — take a note of it and tell us. The price on your confirmation is the price of the trip.
