Photos from a visit to the Wooden Boat Centre in Tasmania. The large cruiser was built for the chef Tetsuya. Here is a link to a video of when the boat was fully fitted out and launched.

The dock out to this boat is kind of impassable. However, the boat does not appear to be in such good shape either.

Supercavitation -- creating a bubble of air around a body in the water -- can reduce hull friction drag by up to 900%, says JMS, increasing speed and reducing fuel consumption. A key to the Ghost design, the company says, is the ability to generate enough gas to create a boundary layer around the propulsion pods without taking power away from the propulsion system.

900% ???
I know this is marketing hype, but 900%??
Maybe it's the philosophy of store markup in reverse.
A store sells an item for twice what it cost them, and says it's 50% markup.
Only 50% of sale price is the markup. Instead of 200% of cost.

So is reducing friction 900% actually mean the boat has 10% of original friction, friction is reduced by 90%, and the original friction is 900% (9x) the improved reduced friction?

because other wise it would be negative friction. Can't even imagine negative friction!

It's hard to keep up with the lies and "spin" in todays world.

I thought you were acting kinda cyborgish!

My ex-workmates sent me this link to an amazing video of the Space Shuttle solid rocket booster tumbling back to Earth after it separated from the Space Shuttle.

Check it out the high-def on full-screen, and the sounds of the cooling booster rocket during its descent after separation.

Maybe the government will help you the way it helped him.
