From the same publication, on page 12, there is an article about the Mewis Duct and Becker rudder combo on a ship, the combo which reportedly reduction by 3% for small ships, and up to 10% for bulkers and large tankers. This is said to be virtually unaffected by draft.
I wonder what gains would be had if prop location ducting hull tunneling were applied — assuming no adverse impact on exit angles, wake flows, and so on.
