I figured it would have to be at least installed center of the boat.. how does it work not to be centred but still center mass a boat pretty impressive

Or you can go for the $5 flopper-stopper, a 2' square of plywood suspended over one side (or both), on a horizontal harness with a weight on one side, so it dives on the down-stroke, and levels out on the rebound. Works a treat. Even better if you can hang it outboard on a pole.

[@captainboating360vr7]

I was looking at your website after applying for a position. I was excited that they now have the smaller model, but why can't it stop for aft rolling? you can obviously mount it in any direction.

[@joeKisonue]

Hi. Just a guy. What do you mean aft roll? Bow/stern pitch?. A boat has to ride waves. If you stop pitch you run through waves not over. No bueno

[@Eric_Allen]

@@joeKisonue would it not also increase the chances or having a wave come over the gunnel if you reduce it's ability to roll over a wave?

Sure, but when the waves literally make water stop holding up an entire side of a boat... what happens then?

Can't we use it in a large ships ?

[@DontStopBrent]

I thought this product was a gimmick. I was so very wrong. #stunned.

[@toomanyaccounts]

the principles behind the tech has been in effect for close to 90 years. they just made it a lot smaller and more efficient and reduced the cost a ton. a lot of the systems either didn't work or had limitations such as only worked in port or when underway in certain conditions. plus you had things that had to stick outside the hull.

[@myusername3689]

[@yanassi]

@@FuturesAnalytica sorry, i never sail before. Would limited space be the reason?

[@FuturesAnalytica]

@@yanassi Well, it's because while you're sailing you're going to be keeled over about 10-15 degrees at all times if you're not going straight downwind. a stabilizer isn't going to be able to counter this non-reciprocating roll.

The physical flywheel isn't the complex Part, it is the integration of data coming in from the IMU and feeding it to the pistons which must move the gyroscope along the axis perpendicular to the waves in a motion which will produce a force exactly counter to the motion of boat roll. Good luck with that!

[@kabtennameq]

if you have a 10-ton boat and buy 5.5-ton Seakeeper (smaller than the boat size ) does it helps to reduce the movement?

[@Pithead]

Yes, the boat will move along a lot slower.

[@joeKisonue]

I understand how a vacuum chamber might consume less energy, but in what way would it save weight 🤔

[@scallaway21]

Probably would need more weight for the same effect if you don’t use a vacuum chamber

[@SeakeeperInc]

With no air resistance inside the vacuum, we can spin our flywheel three times faster than if it weren’t contained in a vacuum without increasing power. Since we’re able to increase speed, we can cut the weight by two-thirds of what would be needed without the vacuum enclosure. Learn more here: www.seakeeper.com/faqs/why-does-seakeepers-flywheel-spin-in-a-vacuum/!

[@joeKisonue]

@@SeakeeperInc aha. Yes I got confused because a bit of info was left out. Saves weight because motor can be smaller because rotation of mass in vacuum is more efficient. OK However, you would by rules of physics have to either have a bigger motor or consume more power from original motor which probably had negative affects on battery and possibly the thermal efficiency of the chosen motor in this exact situation. Because you could definitely achieve the high rpm without vacuum but things would get bigger.

[@joeKisonue]

@@scallaway21 no the mass and its usable influence is not affected by vacuum, it turns out the motor would be larger and heavier if the mass had drag.

[@andysong7168]

Vacuum chamber allows it to spin faster, and it can produce same force with less mass with faster rotation speed.

[@thechaosgardener]

Can I install them in skyscrapers for windy weather or earthquakes and charge a ton of money?

[@mariusschmidt582]

If you had one that is 100x the size probably. They are already buildings that have something similar incoorperated in Dubai etc. It's a middle pole with a big round shaped metal ball on top of the building that swings in opposite direction, but it's huge.

[@skunkjobb]

In a skyscraper, the problem is lateral motion at the top against which a gyro does nothing, a gyro can only reduce angular motion.

[@toomanyaccounts]

@@skunkjobb they have the option to add a second system of fins for forward and backward rolling to work with the seakeeper

[@sailorgeer]

The tech for that is called a tuned mass damper. Different principle but basically counters the movement of the building with a heavy suspended pendulum whose period is related to the building natural frequency.

[@andysong7168]

skyscrapers needs to compensate horizontal force from all directions, this can only compensate rotation force.

[@charlesmackeurtan6596]

costs the same as 2 outboards weight of 3 men fuel consumption with go through the roof, speed will reduce drastically Just rig large tyre tubes to either side…

If it will work for your Yamaha, it will come down to available space. A local Seakeeper Dealer will be the one to determine that. Visit www.seakeeper.com/find-us/ to locate your closest one.

[@AntonySimkin]

How much energy does it use? I am building an electric (solar+battery) boat for deep sea sailing. Energy consumption is a very important factor. Thank you!

[@AntonySimkin]

@@poyorudo yeah, looks like that. I am evaluating another options...

[@joeKisonue]

When running and working it draws around 27amps. You can however reduce max rpm and reduce efficacy a percentage and gain total duration per discharging battery.

[@goodisnipr]

@@joeKisonue Amps says nothing without also stating Voltage. Watts is the actual measure of usage. If 27A at 12V, that's 324W. So you'd need a solar panel array capable of 500W, to account for gyro spin up. But, I don't know if it's on a 12V system. Maybe it uses a 48V system, which then means it draws 1,296Watts. That's a significant amount of solar panels you'd need to add to cover 1.5kW.

It’s probably extremely heavy. Did you ever play with a gyroscope as a kid? As long as the wheel is spinning, it’s very difficult to knock one over. Same concept here, but much bigger and heavier.

[@سفيانسفيان-ط6و]

I didn't understant how it influence the boat

[@sailorgeer]

Read about gyroscopic torque. The spinning mass resists being moved off of whatever axis it’s spinning about.

[@geraldvaughn8403]

If you spin a wheel very fast it is difficult to change its direction of spin due to inertia. It wants to stay spinning in the same direction.

[@joeKisonue]

The heavy gyro is spinning on a horizontal axis. If you put a handle sticking out of the top and pulled straight back the gyro would resist with opposing force to the left or right of the horizon depending on which direction the mass is rotating. Sensors detect Port / Starboard roll and act on the gyro chamber pitching it forward/back through mounted pistons to counter roll.

[@Key5ser5oze]

This and many other vids still haven't explained sht about how the Seakeeper actually prevents the wave crest from lifting one side of the boat up while the wave trough dips the opposite side down. Does the Seakeeper's gyro throw some kind of very heavy weight toward the side that's being lifted by the wave to reduce boat roll, is that what's going on? Ten thumbs down for this vid's vague non-explanation of how it works !

[@gyeranrapper6756]

Typical example of the entitled, spoon-fed kids nowadays. You used the word gyro, but you obviously have no f-ing clue about what it does or how it works. So let me make it extra simple for you to digest. 1. There is this place called the internet that you access using the browser. 2. There is this place on the internet called Google where you can type things in and information magically appear. 3. For even more convenience, there is this Internet place call Wikipedia, which has a summary of basic information on a particular topic. 4. Try using the internet to go to either Google or Wikipedia, and search the words "anti-rolling gyro". 5. If those words on Wikipedia are hard to comprehend, then search for "Seakeeper Gyroscopic Stabilization Explained, Pete Schwartz, Cal Poly Physics" on youtube. Warning...physics equations will used to present concepts. 6. If none of those help your understanding of how the Seakeeper works, then putting it bluntly, the problem here isn't the lack of explanation. Key word of the day: T.O.R.Q.U.E.

it isn't a weight it is force from the wheel. I picked this as weight of the human to the bike wheel probably similar to the flywheel in the unit to a boat, but now add the rpm increase.

[@joeKisonue]

Think of the gyro as a hand with 10,000lbs (or whatever) of strength and it is gripping the top of the console and acting on it in opposition to wave input in only a port/starboard axis
