New Gyro Stabilizer MC2X

I am interested in (and therefor continously looking for) a gyro stabilizing system because I do not like things sticking out of the hull of my trawler when it is not absolutely necessary.

The Seakeeper system is very interesting but rather heavy and to my opinion very expensive, especially when you have to install it in a "second hand" boat. And you also have to install a seawater pump for cooling purposes. Besides that it takes a lot of room.

I found a new system on the market that is manufactured by Quick Marine in Italy. They improved an existing system from a company that they took over a few years ago and now they have developed a whole new range of gyro stabilizers for smaller motoryachts.

It is called MC2X. Besides the fact that the gyro does not require a vacuum to function, it als does not require a seawaterpump for cooling down. And you can shut it down without having the generator run. The system (according to the installing manual) does not need much maintenance. The system fits in a box of 60 x 60 x60 centimeters (24 x 24 x24 inches).

It looks also rather easy to install. ( I believe or think)

Today I spoke to a guy of the agent in the Netherlands. They did not install a system yet in Holland, but he said that Quick has already installed about 60 to 70 new systems since they started last year. The former system has been placed in naval ships and megayachts in Italy.

The system for my Beneteau ST 52 (20.000 kg/ 44092 lbs) would cost about Euro 24.500 (about US$ 30.00).

This is excl V.A.T./sales tax and costs of installing and/or necessary enforcements of the motoryacht. (And the price quote is exclusive the new import taxes of Mr. Trump:lol.

I think that this is a competetive difference to other systems (with or without fins)

The link to the website of Quick is:

There is a short demonstration video on YouTube

I have an installation manual uploaded. The second part is the English version, the first part is to practice your Italian. Happy reading!

Thought that this is an interesting development in the world of stabilizing system for smaller motoryachts. The systems seem to become more affordable every year.

Although I think it is still cheaper to stay a few days more in the marina than to go out in a rough sea or windy weather.

I don’t like the 500 hour maintenance aspect. It says you need to have the rubber feet replaced every 500 hours by expert personnel. Depending on how much you run the gyro, that could be every month. Are there expert personnel everywhere you are going to be cruising?

I only did a very quick look, but the the rotational velocity and mass of these look to be less than a SK. Did you compare the predicted roll reduction of an SK9 (probably what your boat needs) to the model you are thinking of? Depends on what you are after, but the old adage of you get what you pay for is often true.

Watched the video and didn't see any conditions that I thought required a stabilizer. Would be more interested in how it does on a crappy day. Those were just swells, not white capping waves.

30K ? how much is a comparable SK

I don’t know what the Seakeeper costs, but what would it cost to change out the 4 rubber feet every 500 hours on a device that weighs 1080 pounds and needs to be done by expert personnel? Looking at the SK routine maintenance, it looks like changing hydraulic fluid, zincs if needed and inspecting for looseness, etc. the routine maintenance for SK looks like it is DIY.

There has been a forum discussion about this gyro for a couple years, here:

Seakeeper 6 $ 42.200 in comparison with $ 24.500 of the Quick. 72 % more

You are right. You should try it yourself at sea. SK by the way uses a similar video for their product. It is just an example of the difference with and without the gyro.

Compared with a SK 6 ( which SK advised) 15,690 to 12,850 = 22 % more for the SK.

Something to look into. Thanks. But wouldn't it be better to compare the DIY work with a qualified worker when you are comparing prices?

But when you compare both systems I think that the best way is to compare first of all the output. SK Advises a SK 6 but that covers yachts up to 20 ton. Perhaps SK 9 (up to 30) tons is a better choice and perhaps a bigger Quick also. Something to look definitly to look into.

The gyro folks are only 1/2 way in the evolution.

A gyro is a great power source , as battery it can be spun up far faster than a common battery can be recharged.

When a gyro can stabilize the boat in transit , AND give overnight service to house power needs , its time to buy one!

Hi,

Here's another gyro MC2, for comparison.

I got a quote from charlton knowles marina in Freeport Bahamas for 16 grand. Hmm, maybe a trip back there for me.

Does the number after the MC2 indicate the recommended maximum weight of the boat for that gyro, as in the MC2 7 would be for a 7 ton boat?

Hi,

I understand MC2 devices in 5 different sizes.

The smallest max 5000kg boat, the next max 10,000kg boat, max 20,000, max 40,000 kg, max 80,000k boat. If the ship weighs so many more gyro on such a ship.


It would seem that Quick buys its own brand for this same gyro and more options for different weight classes?

Please note, prices are considered a 19% EU tax(Germany) that US citizens do not have to pay (tax free shopping)

Maybe that was with the original company?

The link in post #1 says there are nine models from 5K to 56K, so I'm guessing the 5K would be for 5000 Kilograms...

Any in North America yet?

Talked to the dealer in the Netherlands. The shock absorbers need to be checked every 500 hours and replaced if necessary. They are like engine mounts. The manual also says: if necessary.

They are producing a whole new serie of stabilizers. A found this video on Youtube where you can also see the size of the "thing". It is in Italian but pictures tell more than a thousand italian words can say. Building in time should only take a couple of days. .

Looking more carefully at the SK and the MC2X I'd say that both gyro systems are in fact not comparable. Besides the price there are so many differences that you should look at both systems and then decide what to do. But having deep pockets might make the choice simpler.

The dealer in NL has sent me some pictures of the "build in"of a MC2 X in an Azimut 64 (35 k kg). You can see how the basis is laminated to the bottom.

And some more

Mr Blu, you aren't affiliated with MC or Quik, are you?

No Mr Twisted Tree, nor with Seakeeper. Just trying to keep the Forum members informed and trying to answer questions before they arise.
For commercial activities (like advertising one's boat) there are other parts of the forum which one can use.

The good news is the unit can be shut off , allowed to spin down and its usefulness can be observed.

Send a ride report, Please!!!
