    Did you already have that article. I haven't looked at the site for a while so i would have missed it. I saw it on google.

    Hi mate. No, it was news to me. I thought it was a terrific reference to put here.

    Hello everyone, nice to see this thread still lives!

    Remember the Eco-Flettner's rotor retrofit of the m/v FEHN POLLUX? Now a similar installation by that company on another ship - Annika Braren - IMO 9849148 - ShipSpotting.com - Ship Photos and Ship Tracker http://www.shipspotting.com/gallery/photo.php?lid=3291422

    Also, notice how the rotor was improved with some ridges than being completely smooth.

    Very interesting. Thanks.
    I wonder if the ridges actually contribute anything, or are just construction aids?

    I found the Graph hard to understand

    For reference purposes

    The "drag" effect provides forward momentum to the ship.
