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
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!
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…
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.
@@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.
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/!
@@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.
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!
Power requirements for all of our units (as they're different based on the size of the unit) can be found under each product page on our website, www.seakeeper.com!
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.
@@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.
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.
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.
More like multiple hours! It depends on how much battery power you have onboard and what else is using the batteries, but it's easily recharged with the alternator from the outboards!
@@SeakeeperInc okay thank you. i did watch the video on the site and it did say active in 15 min. so did think it only can be active in 15 min. but maybe it was 15 min to start it up ?
@@lindvallpaul9861 Correct. It takes 15 min. to get the steel flywheel spinning to a rate where the unit will begin stabilizing. So when you get on the boat and start the Seakeeper, you can begin stabilizing the boat in 15 minutes.

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.
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 !

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.
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

Thank you!
That's because these are expensive and the company really needs to make their product look top notch
We need to see Seakeeper vs. Haulover Inlet
Great video! Dont own a boat but already want one!
How much power would that thing consume just to keep it running.. id imagine a whole heap.

Cost half the boat and weighs 2 passengers 😭😭😭

Acts more like a lever than a shifting center mass at that point if I am remembering correctly
@@Oldtricksmadenew ahhh I see still pretty cool though too bad they’re a shillion dollars
It is a gyroscopic stabilizer and I think it’s cool that you can see it working

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
@@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?
Bloody
Marvelous!
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 ?
Will the seakeeper 1 fit on a beneteau oceanis 30.1? Smaller boats have more issues with discomforture than larger boats it would seem.
You probably dont want this on a sailboat for obvious reasons.

I understand how a vacuum chamber might consume less energy, but in what way would it save weight 🤔
Probably would need more weight for the same effect if you don’t use a vacuum chamber

@@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.
Vacuum chamber allows it to spin faster, and it can produce same force with less mass with faster rotation speed.
Gyroscopic roll control. Its just like the US Navy. 50 years ago.
JUST.... WOW!
Slap some magnets on that flywheel and get some free electricity.
One of the dumbest comments I’ve ever read.
For what these things costs id rather just use my sea legs
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?
Yes, the boat will move along a lot slower.
Wonder if this tech will work in space if needed.
Lol wut. 😂

@Tony Wolf Check out the lack of BS on this post!
@@SeakeeperInc Not me you're replying to, but honestly I had the same questions.
Okay?....how does a spinning flywheel in a box stop an entire boat from rocking?...
It's called gyroscopic motion - the same phenomenon that makes a bicycle more stable the faster it goes. Read up on it, it's really interesting!
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.
Can I install them in skyscrapers for windy weather or earthquakes and charge a ton of money?
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.
In a skyscraper, the problem is lateral motion at the top against which a gyro does nothing, a gyro can only reduce angular motion.
@@skunkjobb they have the option to add a second system of fins for forward and backward rolling to work with the seakeeper
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.
skyscrapers needs to compensate horizontal force from all directions, this can only compensate rotation force.

@@rski1036 u mean be poor. He needs to be less poor
I didn't understant how it influence the boat
Read about gyroscopic torque. The spinning mass resists being moved off of whatever axis it’s spinning about.
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.
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.
