This skysail should be a backup propulsion to motor yachts. It does not need any mast at all so almost no modification is needed to their structure, just some extra spaces for storage and operating mechanism. Brilliant idea!
@@frankhoward7645 Do you seriously believe the sailing properties of your 11m sofa have anything to do with this? Anything at all? You may as well have asked; "then how is it my boogers taste like the red gummy bears?"
@@phillycheesetake You said, "Motor yachts don't have the ballast required to go in any direction except downwind." Your implication is that one needs ballast to go upwind. Quit eating your boogers and take a sailing class.
@@frankhoward7645 A monohull needs ballast to go upwind, your floating couch relies on form stability. I'm not interested in discussing the physics of sailing with someone who's clearly not an engineer. You're beneath my station, now act like it.
Just like 'WaterSeer' and 'solar frickin' roadways.' I'm an engineer and when I heard "Fuel consumption can, at times, even be reduced up to 50%" I knew it was bullshit.
@@dieselscience as an engineer, you should know to look at the actual test conditions, for said claims... ROFL. but yeah i'm assuming they are talking about when the vessel is only moving along at like 2 knts, or some stupid impractical speed, or an smaller ship then you might be thinking of.... and for your comment to cargo ships en.wikipedia.org/wiki/MS_Beluga_Skysails, it's only 433 ft. and looks to be more of regional/smaller port ship, with it's built in cranes.....
Any video about this on how to install this on a small skiff? I don't know anything about sailing but this might be what I need coz I can't afford the gas
That equipment on board and its installation must be hellishly expensive. Plus downtime for installation, training and sea trials. I would also think a system like that should turn a profit within a year.
i am a fitter since 1994. i have an idea that can save fuel by modifieng the flywheel of the main engine. it can be used anywhere the ship sails. i am interested to work with you to make this happen
@@dieselscience it can be upscaled and have multiple sails on one line, f- off with your pessimistic caveman grunts, people like you are why we are stuck.
@@solstar4778 With a Skysails system aboard I take it? Pray tell. Your experience as a sailor may be a handicap here, as kites work differently. Don't equate kite area to sail area - the kite moves at about 5x vessel speed here, hence generates 5x as much pull per square foot. Add to that the higher winds aloft and you can mentally multiply that kite area by a factor of about 10. That's a 150m² kite - so imagine a 1500m² Bermuda rig. They saved 15-20% fuel over the entire journey, crossing the Atlantic in both directions at their normal travel speed. Averaged only over the times the system was in use, fuel savings were 20-30%. Peak savings under optimal conditions were 50%. Again, this is field recorded data , not an estimate.

What a magnificent achievement this product is. Wonderful.
Reminds me of space sails for long voyage missions. Very cool system.
can this kite be installed on a smaller ship? and is there a windspeed/ force output chart?
Have you tried to put the base of the cable in the midle of the boat?
Any information about using on smaller boats of 41ft-50'ft .
Look for "Kite Boat Systems". They sell this technology for smaller yachts.
but why didnt it catch on , fuel prices keep going up , so its a better idea today than its ever been , but im not seeing it being used ??
8 years later, and nothing...
Chuk Wow how is your design doing?

The all electric Silent 55 sells it as an option

this is brilliant! approximately how many vessels are using this technology.... and hhow can it be made more affordable?

Very clear and informative video.
Any video about this on how to install this on a small skiff? I don't know anything about sailing but this might be what I need coz I can't afford the gas
Old video, what has been done with it?
Why not adapt it to larger sailing yachts....
This can be scaled up to a larger version or multiple sails on one line then nobody can say it isn't powerful enough
Hallo ... ist dieses wirklich nicht mehr aktuell, als nicht durchfuehrbar ...??? Wartend auf Meldung ...
Why hasn't this been done before?!
And why don't we see it prevalent?
Because of physics?!?! Everything that's ever promised "significant reduction in fuel consumption" turned out to be bullshit.
It is way too advanced and expensive. If a 10 - 35 % reduction in fuel consumption pays for the kite in 3-5 years, then it is really really expensive.
Does the data support that the system at least pays for itself?
If they put chairs on the dam thing it would be a kick ass ride too.
richtig geile Technologie
Just taking cues from the mariner's trimaran in the movie Waterworld
What happened ? kite lost?
Hi, how many lines do you use in your kite?
4
Amortizing in 3 to 5 years what the hell does this thing cost?

One of those based on what we believe we can save you instead of a standard cost
Often ship owners lease their ships, it's the operators that pay for fuel.
Doug Mcdonell good observation
LOVE IT :D

Hallo Gesetzgeber, aufwachen !
10 Years discussion and advertisement but no success up to now.
I wonder could this kite sail be combinated with rotor sail, in order to save more fuel?

It's better the kite must have tail for fly stabilizer to avoid kite diving
Not on a parafoil
Great concept, one decent puff and she'd be shredded
Buried by big oil im sure...
No, buried by physics in the real world.

Over ambition estimate of saving ! Real estimate probably .5% not 50% ! Maybe a secondary control in the pilot house !
That "over ambitious estimate" is actual data collected over an Atlantic crossing by a freighter... so what's *your* expertise?
lino tune just one crossing as a deep water sailor !

A video that buffers! Someone keeps this video on an old server. Don't really want people to see it.

You cam steer a parafoil to avoid crashing.
Requires too much skill
It's on a computer-controlled autopilot, including automated launch & recovery. RTFM
sehr schlecht
Warum?
Stupid project. Look at a sailboat, come back, correct it.
