Japan’s Mitsubishi Heavy Industries says that it has successfully installed its innovative “Mitsubishi Air Lubrication System” (MALS) for the first time on a ferry and has confirmed over 5% improvement in fuel consumption. The experiment marks the first time the MALS system has been applied on a ship with a slender hull form, meaning a vessel with a relatively small block coefficient (Cb). MALS is MHI’s proprietary technology that reduces frictional resistance between the ship hull and seawater by introducing a layer of air bubbles blown from the ship’s bottom.That is one gallon of fuel in 20. Real savings; not pipe-dream props. Don Ho approves.

Time to hit this subject again. .... a 5% saving in a proven technology is something the USN should be at the front of ... not behind.
