The first Royal Netherlands Navy (RNLN) warship to be fitted with a novel hydrodynamic ‘wing’ is demonstrating efficiency and performance improvements in line with forecasts, according to both the Dutch Command Materiel and IT (COMMIT) and the company responsible for the modification.
I have been following this innovation for over eight years. Previous posts are listed below. This is at least the third patrol vessel equipped with this system. It has been used on French, Dutch, and Danish government vessels. Apparently previous applications have performed as advertised.

In addition to an overall 10% or better fuel savings, additional advantages include reduce air pollution, better seakeeping, quieter operation, and reduced motion that allows reduced crew stress and safer boat and flight operations.
It is certainly worth asking current users about their experience with Hull Vane, effect of marine growth, operation in ice, cleaning and maintenance requirements?

I believe this video better aligns with your post than the old one you have used
Thanks for the suggestion. I replaced the earlier video.
Worth trying on one cutter.
Looks like a yacht
The integrated mast on these ships is extremely sophisticated and very expensive for a ship with no AAW missile system. Pretty sure their 76mm guns were recycled from now decommissioned ships.
Seems to be a good idea with no downside.
I’d be curious to see the long term results of it’s use over several years to see if there are any unintended negative consequences.
The Europeans are trying it, apparently with at least initial good results. It will be telling if they don’t apply it to other ships, but why not simply ask to see their results? The latest test is almost perfectly designed to test suitability for the OPCs.
Completely agree Chuck but that would be easy and make way too much sense. Both of which are contrary to USCG ship building. FRC’s being the exception to that of course.
There are a lot of technologies working on efficiency. I recently ran across this video. Makes one think what would happen if engineers combined the hull vane with some prop optimization.
