You don't get to wear a green hat, but .....

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.

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.
