Hybrid Yacht launched in Germany

she 's not a beauty in my eyes but got some interesting novelties.


A new positioning system that makes it possible to hold position without anchor. In combination with its hybrid engines she could sail into protected environment like reefs.

The article claims that the hybrid system will be 30% more efficient. I see the same number for cars, but cars rarely are travelling at a constant optimum cruising speed. It seems to me a diesel properly geared and propped for the cruising speed should be more efficient than a hybrid.

Maybe the intended use is to almost never be at cruising speed, perhaps using the engines to hold position instead of anchoring as touted in the advertising.

It looks like it got hit midship by an ugly stick.

Novelty item, I can't see 6kW of panels taking it far.

If your referring to it's Dynamic Positioning capabilities that technology has been in use since the mid 1960's, Cruise ships and Superyachts have been using it for the last 10 to 15 years or so.....

Certainly have been some offbeat designs of late.....

so I would say that positioning systems based on satellites for civilian purposes are in use since nineties. In 2000 Selective Availability has been switched off. Topic here is automatic positioning without manual intervention. Although a ship in a reef makes me shudder.

I doubt the 6kW of panels will even power the air conditioning, watermakers, galley, lighting, spa heating, etc. That being said, no matter how much, or how little, solar you have, it all helps reduce the need for generator run time.



Guess the PR guys had to come up with something to promote the designers and yard.

Not sure why you are referring to selective availability, it's really got nothing to do with the subject....civilian use of GPS dates back to the early/mid 1980's....

The topic/technology 'automatic positioning without manual intervention' as you put it.....correctly termed Dynamic Positioning......is not new to this vessel at all, thousands of vessels world wide have been using DP, with GPS, to maintain position and heading 'without manual intervention' for years......the "new" tech they are promoting with this particular vessel is it's Hybrid drive systems, it's DP system is a feature only......

From the very same website you linked to, from 30 May 2003.....

The recently launched 51.75 meter (169’ 9”) Feadship Dream is fitted with an advanced retractable azimuthing sternthruster, linked to a Dynamic Positioning System. Used in combination with the bowthruster, this holds the yacht in position in a bay or other special deepwater location, removing the need to anchor during shorter stops.

Doesn't even have to cost much....

Do the ugly windows make it more efficient, or is it just easier to find in the middle of other superyachts?


Somehow, I never really think of superyachts when I'm thinking of energy efficiency, and that's not likely to change.


Energy efficient is a little sailboat,not a luxury yacht.

Thats right, Volvo Penta have had a system out for 'smaller' boats for some time now, not as small as that Minn Kota though...

Oil drillers have had dynamic positioning since they were developed for the Moho Project in the early sixties. The early ones used sonar transmitters placed on the sea floor with four receivers through the bottom of the drilling vessel. I think the first of the DP drillships used for petroleum exploration was the Sedco 445.

Offshore Oil & Gas and the US Military worked closely for decades on the development of DP, using both terrestrial and celestial applications, the relationship was beneficial for both....

I've been using it since the mid 90's in the OO&G industry on AHTS vessels....

Interesting to see the GMDSS type systems moving into yachts. In this case I find it strange due to the high power requirements. The boat itself isn't that groundbreaking given its commercial characteristics. But this seems to be the way many designers have gone in recent years. I'm guessing if it works in the offshore oil industry it works on a pleasure boat.
