Probably works but not for everyone. There are different types of
stabilization systems. We have Naiad hydraulically actuated fins on
our trawler and they work very well:

The drawback is that the boat has to be moving at least 6 to 7 knots
for the system to become effective.

The type with a massive gyroscope works at slow speeds and at anchor
but the gyro takes up a lot of space, consumes quite a bit of power,
and the vessel structure has to be designed around the loads produced
by the gyro, which are considerable. You can't just drop one in to an
existing boat.

I belive you're right, Wayne. Seeing the craft isn't made for it, it
would need quite a bit of re-structure work. And yeah, what's their
idea of 'very little power'? probably different than mine.

ScummyBadger, aka Dan Krueger, has two little boats, one an aluminum
fishing boat of about 17 feet, and the other a fiberglass center console
not much larger. Either stabilizer would suit him perfectly, of course. :)

Better for him to stabilize his head... and then worry about his
little boats.

They do look like they take up a lot of space but they come in different
sizes for different applications. On paper they are amazing!

IIRC 3kW for start up. After that - not sure from what I've read.

I am not sure how a big gyro would work unless it was just a servo to
control some other stabilizer. When you try to alter the orientation
of a gyro, the force is translated (precessed) into an equal force 90
degrees offset in the direction of rotation. If you had a fore and aft
motion, it would translate into a roll.
We had a big honking gyro (washing machine sized) as a stable element
for the fire control system and it only controlled a servo sensor the
size of a table fan motor..
The demo on the site makes it look much simpler than that. Of course
they are trying to sell them, too!

Then you realize that you have to keep a generator running 24/7 to
keep the gyro spinning.

There is a system called an "Anti Roll Tank" that some people have had
success with on pleasure boats in the 40 to 60 ft range. It requires
a custom design unique to each boat however. It usually requires no
power at all, and is effective at slow speeds and at anchor.

For a discussion of all types of stabilization systems, take a look at
the following:

The goal is to stabilize a 50' power catamaran at rest in rough seas for
more comfortable fishing and mooring. The anti-roll tanks would
probably add a lot of weight.

=========

Anti-roll tanks do add weight but they can be emptied out when not
needed.

Most power cats need very little stabilization compared to a round
bottom displacement hull. That is one of their strong points. It is
impossible to eliminate all motion. What the stabilization systems
are good at is damping down the amplitude of the initial roll and
eliminating recurrence of the "roll back" oscillation. Multi hulls
tend to be self damping and usually have very little roll back motion.

The vessel has a 22' beam so, at rest, there can be considerable roll
from side-to-side depending on the seas and the wind direction. It is
very comfortable underway.

Commercial fishing boats almost universally use paravanes hung from
outriggers. The outriggers are heavily stressed and require a great
deal of supporting structure. They also increase air draft when
retracted, and not everyone considers them to be aesthetically
appealing.
