Just like renting a car, when chartering a boat fuel is an additional charge. The boat owner is not looking to profit from the fuel and generally fuel consumption is calculated by approximating the number of hours the engines are running and how much fuel they use per hour. If the boat is driven at top speed for the entire charter the boat would use more fuel than the cost of the charter itself, many times over. Each boat has an estimated fuel consumption value listed on the boat specification page of our website. Also, another factor to take into account is the speed of the boat. A very fast boat gets to the destination much quicker than a slower boat, so per hour it’s more, but overall it can be less. We advise discussing any fuel concerns and agreeing a fuel budget with us or your captain before setting off.
