There are a few builders that have, umm, err, relationships with their navies. Unless the materials are proprietary it doesn't make sense that they'd not seek to utilise those advances in other divisions.
On the other hand, despite the advantages of pod drives as demonstrated on Air/ICE, there do not seem to be many embracing that option.
Unless there were issues with the pod drives that have been kept under wraps it makes no sense to me that they were not used in a vessel like A, which sure as god made little green apples, isn't the most conservative recent build.

There is another paper with drawings I've seen again for ROv's

Here is one version

These would seem a workable option for a submersed vehicle, but for any surface vessel the roll forces may make them unviable as they would have to be very rigid, or retractable.

I know some builders of submersibles through work and there is some very interesting work being done on propulsion systems.

This thread gave me an idea.
Imagine that the entire external wetted surface of a craft is covered with fish scale like skin.
Every single scale is controlled individually like a pixel on a TV screen.
The scales could be nano size and only affect the boundary layer of water.

Shark skin coatings are used now to reduce drag. Just make the coating dynamic.

Guidelines on Avatars...

In order to maintain a professional format at YachtForums, we've established a few guidelines regarding avatars and we would appreciate your cooperation...

1. Flash or animated avatars are prohibited.
2. Keep avatars to 100 pixels wide, preferably less.
3. Avatars should be marine and yachting related!
4. Signatures are to be kept brief.
5. Commercial URL's in signatures are strictly prohibited.
6. Cartoons, faces, bikini girls, etc... are not appropriate.

Avatars not meeting the above requirements will be removed.

Isn't www.modin-design a commercial URL in a signature? or am I being pedantic?

What in the world does this have to do with propulsion???

Skiffy, if you want to re-direct a thread, then I'm happy to intercept. And just to be seriously pedantic, I have re-directed AMG's signature to the Special Feature we published on him.

Returning to thread topic now...
