    Headwind power

    A windmill powered boat can sail directly into the wind that powers it. Recently, I put up a page on my website of a simple model to demonstrate direct-into-wind sailing, Direct Into Wind Demonstrator https://windthrusters.net/windoppose.html This model has more drag behind the clr than in...

    When will leisure craft adopt the new sailing systems?

    In the world of shipping many different systems are starting to be adopted to give wind assistance. These include Wingsails, Suction towers, and Flettner Rotors. These would appear to give handling benefits over traditional sails. These systems would be much simpler to operate and still give...

    Best settings for direct into wind

    We see from this video that this boat can progress directly windward driven by the wind. but how to calculate the correct settings and gearing between the wind-turbine and water prop?

    Finding the best way to sail directly upwind

    Generally accepted now that a boat with a windmill can go directly to windward. Is there not a need for further research into this? https://windthrusters.com/images/windtunnel.jpg

    When will new ideas be adopted?

    As a whole sailing using the wind is based upon long established ideas and technologies. Whilst it is nice to enjoy the knowledge gained from hundreds of years of tradition there is a need to embrace new technologies which are emerging and to no longer ignore the future. For example in the...

    Sail Directly Upwind (a reminder from the past)

    Hi All Not much progress has been made recently on a rig that can allow a boat to sail directly upwind. It seems a useful feature. I make no apology for bringing the subject up again. I'm just raising this subject to remind all that such a rig is completely possible. It just needs someone...

    Directly against the wind?

    Using the wind to go downwind faster than the wind seems an established fact now (reported today on NALSA website). But as yet, nobody has thought of a practical use for this technology. In the opposite direction, going directly against the wind should surely be more useful, since sailboats...

    Boat propulsion using windmill power directly

    As everybody knows :) A windmill powered boat can sail directly into the wind that powers it. Recently, I put up a page on my website of a simple model to demonstrate direct-into-wind sailing, This model has more drag behind the clr than in front and weathercocks automatically to...

    Does a "steady wind" exist?

    Much discussion takes place about different sails, lift to drag ratios, efficiency of rigs and many other points about sailing, but there is not very much consideration about the nature of the power source sailors use - the wind. Most of the discussion that takes place seems to assume that the...
