Weight is the most important factor for fuel economy in boats. Crusing boats usually have poor fuel economy, under 2 miles per gallon, hence they usually only report fuel usage in gallons per hour to hide the poor economy. See http://www.boattest.com/ for various fuel economy figures. 


Pontoon boats are very light catamarans for their size and capacity because they use the cylindrical shape for strength and rigidity, thereby minimizing the need for more weight and cost of aluminum. 25ft, 25 in. diameter, pair of pontoons only weight 500lbs. 




Manufacturing defect warranty 5 years on aluminum and welding on the pontoon tubes. Pontoons made from 50xx aluminum, built for salt water. However, damage from corrosion and salt water is excluded from the warranty due to the risk of inadequate galvanic protection with sacrificial anodes.

Pictures show most of deck bracing installed on the 25 footer. 0.090" thickness aluminum is normal gauge for this size pontoons. We pressure test all our pontoons to make sure there are no leaks. Up to 8' air sealed sections, at least 6 per pair for safety even if collision makes one section leak. Have live/well pump/depth-fish.finder tabs on pontoons. Most have Lifting/mooring eyes on both ends. Check out my trailer website WORDBoats We can build any length from 14-26 ft with whatever you want: deck, flooring, fence/rail, motor pods ($400-1200 depending on HP rating), steering consoles $500.
