Interesting concept of a modern cargo windjammer:
http://www.mantamarinedesign.com/projecten/Ecoliner.html
http://segelreporter.com/blog/2012/02/17/geplanter-oeko-frachter-aus-holland-ecoliner-soll-mit-dyna-rigg-segeln/ - says such ship will be built in 2013.

The ecoliner is a type of cargo vessel propelled by a combination of high-tech sail and engine power. This hybrid feature, makes it possible to offer you exactly the same service of speed, freightprice and trustworthiness as expected from a traditional motor cargo vessel. While maximising the sustainable gain, without having to change your logistic systems. Making use of ecoliners, as ocean transport means, does decrease the polluting emissions of ships by minimum of 50%. Feel free to contact us about the possibilities of chartering the first ecoliner.
Dynamic Dynarigs
The Dynarig concept continues to evolve, with the 130 meter Ecoliner currently on the drawing boards at Dykstra Naval Architects as we test various options and layouts. After the success of Maltese Falcon, This square rig design has certainly proven itself in terms of both speed and ease of sail handling on a large superyacht

I like the idea of combining masts & cranes:

Didn't some company trial something like this quite a while ago now and the concept for large cargo/freight ships fell flat and the idea was dumped pretty quickly. It's ok being eco but surely it's just the ship's engines that should be eco-friendly?
-
Not just to lower emissions by use of a more eco-friendly engine but to save fuel as possible. I read on E-SHIP 1 fuel consumption is reduced on 30-40% with just 4 dumb rotors. Not sure why someone would build a 4 masted comlex dynarig tallship with inconvenient un/loading of it's cargo when it'd be much easier to put rotors or at least a retractable wingsails or whatever.

Why?
The recent concepts have been relatively small ships for local trade. How about transporting large amounts of bulk raw materials that are not time-critical on large (partially) sail-driven ships? Valemax with sails, anyone?

Can't see it getting very far up the Rhine!

Here's a brochure about this whole modern windjammer concept:

Another concept of the dynarig cargo ship:

You can see absolutely "green" and "eco" ship on this picture :)
but there are no seamen who want to change their "one galleys" to another.
I don't think that this kind of projects has future, hope never.
Much better at present moment to modernise the idea of azipods with low consumption engines as power source.
I prefer to believe that in future we 'll see "eco"-world with "eco"-ships but how many years from now? nobody knows...
-
That maybe is a good idea for someone.
Not for me!
I don't like it, how will they be loaded on container terminals or any other?
What if they have to sail under some bridges?
I guess most companies will use "normal" ships for carrying cargo, you need an experienced crane men for loading this boys.
Maybe, this would be more useful if they would have retractable masts like funnels of the oasis of the seas.
So when they come to port, they will be able to retract them.
Concept can be made on retractable fishing rod?
Those were my first thoughts. :)

Mark, I have very same thoughts regarding cargo operations & passing under bridges. I see B9's ship has small cranes, what if it would require a harbour crane anyway?
Also, small open deck spaces & unusable forecastle (I think) - dynarig concept could be good for a tanker or passenger vessel, but this as cargo ship - it will be in a darkest shadow from normal ships, especially like Hartman M2 Runner (those odd Oceanic & Nordic).
-
Denis,
Good idea, she would be useful tanker!
I looked out of my window ( i can see the whole port ) and saw 100+ kmph wind gusts and though:
What if those gusts will be in some other ports, how will she be docked?
Looking forward to anyones reply,
Mark
-
Yes, docking such ship in ports only with the help of wind would be a fun challenge.
-
You can use the engine during docking even if you have sails. Or a tugboat.
Those ships are quite small. I would expect sails to re-appear on large long-distance tankers and bulk freighters at first.
-
Tuomas: I think motors won't help when speed of wind gusts in port is 100+ kmph?
What do you guys say?
Cheers
Mark
-
I prefer this concept which looks more futuristic. And of course a lot of problems to realize this concept into a real ship.

Try to look at containerships mooring operations during strong wind gusts, especially for feeders at Rotterdam and Hamburg, when charter want to save money and they have full tiers on deck.

How often do ships even come to port if the weather is like that? Also, not all ports in the world have such extreme conditions.

Toumas, : I didn't thought about that.
But let's make some kind of conclusion, wind will be one of their biggest problems, after bridges and loading and unloading cargo operations?
This is good idea for a tanker.
It would be ugly but useful tanker, right?

Shipowners will be one of their biggest problems, nobody likes to spend money in the air, untill something become regulation...

The device for saving fuel should be as "simple" as possible & require as less as possible costs on it's maintenance. Dynarig is significantly inferior to a Flettner rotor or just a kite as it seems.
