    That really cracked me up. What's missing is the slave driver with a whip and the guy banging on a drum.

    whats wrong with sculling,I have done it on a 30 ft yacht(3.5 tonnes ) into a marina, Its easy. Obviously no wind blowing and had spent an evening on a bouy just outside the entrance . engine had failed and could not raise anyone from the marina, waited till wind dropped right away as was blowing straight out of the entrance, and in we went.
    Being long keeled, we did not fancy the 4-5 tacks to get through the entrance channel.
    sculling has been done all over the world by fishing boats and on a lot bigger than a 25 cat.

    I saw a pair of these real wierd diesel Chinese outboards on scow/houseboat in Seldovia AK 20 years back. The lower unit was real beefy maybe 5 ft long turning a 20" wheel. It looked like a seagull on steroids. At the top it had a flat universal mounting plate. A one lunger diesel motor was bolted onto this plate. It had a belt that ran from a shiv on the motor to a shiv on the lower unit. I have wished many times that I had taken a picture of it. I've never seen another set up like it, either in real life or on the internet.

    I've never really seen it, but there is a European patent granted to a lunatic who puts the outboard engine inside the boat in a sort of long tub. The water expelled by the prop flows forwards on both sides and returns to the prop.
    The inventor points to the advantages, such as using clean or distilled water to prevent growth on the prop and easy maintenance. He claims the innovative propulsion can also be used for trains, planes etc.

    It clearly shows that proving something stupid will work by pointing at a granted patent in fact only proves you are not the only idiot around.

    I seem to recall that an engineer in Australia was granted a patent for a "circular transport assist device" or some similarly stupidly named device.
    I think he did it to show what clots work in the Patent Office.

    Any new proposal or patent should always be viewed as a ****, before studying it.
    It will not open you a lot, but else, this is chaos, any idiot will feel like talking about idiot claim.
    And if the **** works, idiots will mess with our smart and good looking business.
    No thanks.


    So only tested, and marketed, new ideas, please.

    Boating is serious.

    Kistinie, do you ever have anything literate to offer a thread? Is it a translation issue? Because every time you enter a thread, your comments are illiterate or so out of hand that I'm quite unable to figure out what you intend. After your participation in a thread, one of two things occur, you are ignored and very rarely you actually contribute to the thread or the thread dissolves into discord around your incisive illiteracy and frankly often lunatic ranting.

    I'm IHIQS (143 for those that know), so understanding you shouldn't be a problem.
