They use little if any fuel. But if we confine the question to motorboats what do we get. Fuel efficiency implies carrying the most cargo at a useful speed with the least fuel.

One important factor for me when I am looking for a new boat is the fuel economy. Some might argue that if you have to ask you cant afford it and while that might be true with the cost of marine fuel and the low fuel economy of boating that can add up quickly. So I have decided to create a user-submitted database of boats and their fuel economy.
A cursory glance at the lines of most boats proves that profiles havent changed dramatically over the past 60 or so years. Certainly construction methods such as resin infusion and injection molding have altered business as usual and ingredients have also changed to include all manner of space-age composites epoxies paints computer mapping for engines that produces vastly. If you plan to fish on rivers and small lakes flat-bottom planing hull boats are some the most fuel efficient boats you can use – just remember that these types of boats arent suited for large choppy waters.

Because a multi-hull boat design has narrower hulls this design means less resistance or drag on the surface of the water and better fuel efficiency. The 70 Sunreef Power JAMBO is a rare example of a luxury medium-sized power yacht 60-80 feet with extremely high fuel efficiency trans-Pacific range and top speeds reaching 20 knots.

GCYWe have been approached to develop a maximally comfortable and fuel efficient boat to compete with our own catamarans. We have spent considerable time creating a 70ft wave-piercing power trimaran to compete with our 60ft wave piercing catamarans. This eco-friendly design is estimated to be a lot more fuel-efficient than typical monohull trawler yachts and 30 percent more fuel-efficient than power catamarans.
Designed by Bernard Nivelt et Pierre Frutschi these boats are true liveaboard yachts that can be easily operated by a husband and wife team. Strong Fast and Fuel Efficient. C-Dory has been taking boaters to seldom visited waterways favorite fishing holes dive reefs and waterside communities for over 30 years.
