Hydrokeels and other such nonsense

[kach22i]

A hydrokeel is a little different from a type of hovercraft known as a SES (Soild Sidewall Ship). From what I can tell a hydrokeel is going to depend on displacement mode or buoyancy if there is even the slightest wave activity.

So to all the boat guys out there who know all about stepped sponson floats, hydroplanes, air cavitating catamarans, tunnel hulls and the like - have you ever encountered a Hydrokeel?

During 1939 Louis Courant patented a gliding machine in which « the liquid element » did not react « statically or dynamically » to the vehicle movement. Air was taken out of the big front intakes by two engines and ejected under pressure to form a « fictive hull » (think « air bubble » ). Forward propulsion was obtained by air exhausting through the rear (hence two engines and a segmented hull to allow for lateral control). To allow for rearward movement , air could be directed to two front « flaps » to eject at the front of the machine.
The real hull features curious « air traps » at the front. For the same use we now use skirts.
This would now be know as an « hydrokeel hovercraft »
No prototype was built

Note: I don't have the proper program to view that last link with. If anyone has the "Compupic" or a similar graphics explorer type program to access the images, please help us/me see these things larger. Thanks, George/kach22i.

Interesting idea to be sure. Have to take another look when I'm actually awake.
Afraid you'll need to buy the CD to see those images, George- I couldn't find the full-scale ones on the site.

History does repeat - below is the modern version. The old stuff looks so Jules Vern like - gotta love it.

The patented SeaCoaster catamaran design features cavities in the bottom of each hull into which air is blown providing lift to the vessel, reducing resistance, and thus allowing higher speeds to be obtained. Designer-inventor Don Burg expects speeds of up to 56 knots.
