    up to 50% fuel savings .... it doesn't have to be a cheap, easy to use, or fun, or pretty solution.

    It is about the DOLLARS ....

    You said fuel costs how much?

    I don't think 10 knots will impress Mersk or Evergreen. Try 25 knots.

    Perishable and frozen goods!!!!

    If your not on time for the suez or Panama you could be put back days.

    Its a risk for not much benefit.

    IFO 380, about $620 a ton.

    http://www.bunkerworld.com/prices/

    10k ton ship uses about 10 tons a day at 10 knots.

    One wing of a jumbo will lift half of 340 tons so 170 tons.

    Thats not much push for a 160,000 tons ship.

    Plus the wind needed to generate that lift alone is 180knots for rotate on a 747.

    You will be lucky to get 30.

    6 thou a day? 20% saving already demonstrated?

    $1200 a day. THAT IS MONEY IN THE BANK .... KA-ching.

    And I am just a consultant, not even a sales guy.

    ;)

    Actually.....most of the small cargo ships (1k to 12k) run at 10 to 13 range.

    This is not feasible in container ships. They run too fast to get any benefit from the wind. It's more for the small cargo ships and small chemical tankers to handy size. Not Panamax or larger. I can't even imagine the size of sails to help a ULCC.

    LOL! I have NOT demonstrated ANY saving because I can't stick any real numbers to it.

    Go kites!!!

    I had looked this up LONG before you asked the question. KITES!

    Wind speed at altitude is MUCH MORE CONSISTENT AND FASTER .... than on the deck.

    I do LOVE to fly ....

    So, if you KITE, instead of sail, your wind speed is predictable (AND YOU CAN CHANGE ALTITUDE TO CATCH A FAVORABLE WIND .... )

    Sustainable, proven, and money in the bank .... especially ON PANAMAX .... Can you imagine the fuel savings with 5 full size kites in the air?

    Spartan, the numbers are easily found.

    They have ALREADY done the test runs with a shipping company out of Germany. It was mentioned in one of the links.

    I had already spent 20 to 30 hours researching this.

    It even takes me time to analyze data ....

    I'm confused by your English. Have you crunched the numbers? Show me.

    They already crunched the numbers. You can find published data, not raw numbers, online.

    Sorry about the confusion. I had spent hours researching this before. My answers to you now are quick, because I had already studied this.

    I could not respond to your question this quickly with this detail, if I had not already researched the question.

    I hope that is better.

    Where are the numbers? I know that Wilson has done it but I did not find any published numbers. Nor any papers.

    Here is the MS Beluga data.

    http://www.ship-technology.com/projects/msbelugaskysails/

    It is a container ship .... WITH REEFERS .....

    "On route, the efficiency of the SkySails system was tested for up to eight hours a day were applicable in winds of up to force five. The system was hailed as a success, with calculated savings of up to 2.5t of fuel/$1,000 a day. With larger sails of up to 600m², fuel savings of between 10% and 35% are possible. The Beluga SkySails will have a new 320m² sail installed as a continuation of its pilot testing."

    And later:

    "With the price of oil so high, an average 87m cargo ship could save nearly €300,000 a year. The system can be potentially retrofitted to any ship and SkySails estimates the potential market to be 60,000 ships over the period up to 2013."
