Chinese gyro stabilisers

Has anyone ever seen these before? i wonder how cheap they are...

Why mechanical and not solid state ?

Be interested to know how it would be integrated into on-board system ...

It needs plumbing in….so do they regard it as a DIY fitting or do they have dealerships. If they have dealerships in France, they will price them exactly the same as Seakeepers…just the way they do things here.
While I deplore the de industrialisation of the west…my ears do prick up when I suddenly find I can afford something…bad I know.

USD 55k for a squadron 58. More than a sea keeper.

I'm going to have a word with pals of mine about solid state Gyros / Stabilisers we use in models ... they send signals to servos / actuators to command various .. their response to any deviation from programmed attitude is instant and proportional.

I just have this crazy idea that such a unit could provide the sensing ... then its a matter of identifying the intermediate control items.

My Primor has touch button control for trim tabs ... crosses my mind whether it could be used to control based on signals ....

Just me thinking ... excuse my invading this thread.

Perhaps Elon needs to get into the boat stabilisation business….implants could be activated every time a swell is detected that causes all your passengers to move to the opposite side of the boat

solid state sensors are everywhere - they cant however impart a force which is what the gyro does. The gryo is relatively uncontrolled. There is a brake to keep it I'm limits but it is not "controlled" per se. It just does what a gyro does which simplistically is stay upright.

Sales lady says about 10 grand for one for a Swift Trawler 34.

Looks like it is water cooled similar to a Seakeeper rather than Quick’s air cooling.

If the Chinese can knock these out at a sensible price and engineer them in a way that they are reliable / easy to fix they will sell loads of them.

You’ve got completely the wrong end of the stick.

They are referring to mechatronic control in as much that the precession of the gyro is controlled by an electronic servo motor rather than a hydraulic cylinder as in a Seakeeper.

The control / sensing side will no doubt be using a $1 chip same same as is used in remote control drone.

That would make an interesting proposition…. I would not like to be the first…because it is easy to underspec an installation just so it sounds cheap.
And size is going to be interesting as on smaller boats there isn’t the room

Relocate the fuel tank?

Sorry - you have misunderstood my post.

I am actually quite well aware of a gyro and precession etc - having been responsible for various Gyros on ships : Anshutz - Sperry as examples ... and the Japanese copies ... along with gyro stabilised fins / flume tanks etc ...

My post was about generating the corrective signals using solid state gyros and how to use the signals to command actuators to keep boat stable ...

The stabilisation will be based on a generated signal to correct the attitude of the boat ... the signal itself will be low power whether from a mechanical gyro as they are using - or as I am pondering - a solid state one.
The signal causes an actuator or solenoid as example to operate - creating the higher power needed.

How much power do you think the 'touch buttons' make that alters my trim tabs on the 24 at 25kts ?? Small because the signal activates the hydraulics - which have the required force.

Anyway - as I said - Its only an idea in my head at present ... and I have asked a few pals of mine who know more about using such signals etc.

Seakeeper only say they are good from zero to five knots….after that you need fins

All Tesla’s are all unstable , we took one on a track day and come back with a Vespa .

Interesting story behind Lambretta and Engineer breaking away to make Vespa ... all started from an excess of metal tubing after the war !

Still too soon

Can you imagine Bouba thread fitting them.

He’ll just strap it to the passerelle
