Marine Link reports on an innovation that promises a better ride, fuel savings, and lower emissions.
If it works nearly as well as reported, its worth a look.

Very interesting. Seems like a heavy system however. Would love to learn more regarding catamaran applications.
Large catamarans typically need ride control devices so I was not surprised to see these applied that way, but was surprised to see it applied to mono-hulls.
Looks similar to the LCS 2 class bow fins. It would likely reduce pitching but if the vessel did not have a high enclosed bow you could get a lot wetter forward.
