Good ideas spread fast, although that Thatch roof construction may be more suitable for the tropics.

How they can make the submarine quiet to avoid detection?
This is fascinating for those that have no idea about how these ships operate!

Great video! Sure would like to learn her prop design that limits cavitation and increases thrust. But, I understand that as being Top Secret... and, I sure don't blame The Navy for that! U.S. needs every edge we can get and keep.

I believe there are some Superyachts running around with some carbonfiber props very similar in design.,...it just takes money

Brian, you are absolutely correct.

How do they hold up on a grounding? Wouldn't the blabdes snap instead of bending or nicking?

Well, apparently the market for fiber props wasn't all that great. A search for "Contur Propellers" turns up a bunch of expired URLs and no information at all. The newsletter Larry posted is from 2004 and the company that pot it out, Fleetwater Marine no longer shows the fiber props under its "Marine Propulsion" section.

One hit under power and I bet those fiber props turn back into frayed cloth they were made from.

I obviously didn't spend much time on the Google search, I just grabbed the first reference I could find.
How about a press release from Michigan Wheel on 11/19/2014?
I suspect the prices are astronomical and the market very small for carbon fiber as a propeller material, yet it is an interesting idea.
For my money, and depending upon the application, it's hard to beat nibral or stainless for strength and longevity.
I guess I'm still stuck in the Bronze Age

Was over at Shilshole Marina today, a beautiful PNW day. Saw these twp on the transient dock next to us. The first is a good looking eahorse, not sure if it is a DD. The cool thing, if you can see it in the picture, is the wheel and engine control on the pilothouse roof. Not quite a flybridge, but close!
The second was the Black Pearl, looked to be something around 75'. The weird part is the starboard hull is black and the port side is white! Can't imagine the reason for that.
BTW-yesterday saw the old carrier, USS Ranger, being towed from Bremerton to Texas for scrap. Long tow as they have to around the Cape rather than through the canal. She was too far away to get a decent shot. Sad to see an old lady go.

From the lighting, it looks like the hull is blue on one side and black on the other. Or, maybe it's white on one side and gold on the other.

...and it is made of composite...according to the write-up.
I would suspect it would reduce cavitation at the end the shaft???
