 What is it?
A steel plate appendage that extends from the hull bottom surface, aft of the propellers.

How does it work?
Stern Flaps modify the way water flows under the hull afterbody resulting in reduced drag, reduced turbulence, and thus, reduced hull resistance. 

What will it accomplish?
Stern Flaps have been proven, at sea, to increase propulsion efficiency and reduce exhaust emissions, fostering significant fuel cost savings while increasing both ship speed and range.
