Martini 6.0 by Servo Yachts (Concept)

Two ama's that will stabilize the hovering main hull.
Not new,

Lubrication will be a challenge.
So will the power supply for this massive task.

When build smaller it's more obtainable.

Not to think of the amount of maintenance.

Enjoy

 

As a controls engineer, I find this concept interesting. There are a few major concepts the system's engineer must have contemplated. Is the sampling rate fast enough to track the waves? Are the actuators fast enough to stay in contact with the water at all times? What is the sea condition under which the system loses its ability to track the surface?

 

Good questions,

Sampling rate must be 0.1 second. in my opinion.
The reaction of the actuators the must be in the same range to react in time on a oncoming slamming wave.
When wave height comes close to 30 % of hull length (150 feet/45 ft) the system is definitly in trouble so that is a safe margin. 45 feet waves seldom occurs, but can be avoided.

The firm isn't called Servo for nothing.

In industry servo's are widely used. It will be costly.

That's awesome... but what about trasversal wave?

The weight distribuition may cause a easy overturning.

But the animation in the video is really amazing!

 

We develop and deliver stabilization packages for a range of advanced marine vehicles; the sample period we would employ for craft as per the OP is .005 sec..5 milliseconds. High-performance servo-actuators are a key component of all such systems.

Corner frequency of the servo actuated effector response is typically at least 10 time higher than the average frequency of motion, wave encounters, etc.

The Japanese developed the first servo-actuated fully stabilized "cabin" above two hulls back in the 1990s. A technical curiosity at best, things get "ugly" when the limits of the active suspension are reached in a seaway.
