    I’m no expert, but I’m particularly concerned about the hinge bolts being ripped out of the wood by a sudden jerk, hence the suggestion about helmets.

    The same bolts hold the two hinge plates on opposite sides of the wood. These are not wood screws but bolts going all the way through. So it would have to break a bolt.

    I think that would take a lever/prying motion by having a leg moved sidways, not in the direction the hinge lets it move. I think the rope will always be in tension and the beams always in compression. And I think the ropes keep the leg such that there is no sideways force on the hinge.

    So I think it is safe. But if there is a “weak link” in this design I think it is the hinge.

    The wind is from the East! I think we are good for a launch today. Going to try.

    Good Luck, Vince. Don’t die. My bookies have you at 3:2 falling off no less than three times. Watch out for sharks!

    We had a great time and nobody died. Getting pictures off the cameras now and will try to upload something before I fall asleep, but no promises. The structure is very stable without the diagonal ropes. The hinges seem plenty strong enough. There were problems and lessons and more on that tomorrow after a good nights sleep.

    Here is a video of todays seastead experiment:

    As Thorizan said, you rock !

    I hope the barrels are/were firmly enough tied to the poles, those ropes looked a bit thin or soft to my liking.

    Working out kinks with scale models is what it is all about, right? It’s awesome that you have the time and means to make this model even possible. The video is great, showing the movement of the seastead over just a few short minutes further and further into the horizon, and the explanation of now known issues (read what to work on next) is very inspiring. You are an inspiration, Vince. Please keep up the great work.

    Thanks. Yes, mostly success and we had fun. I wrote up some and put up some pictures and another video:

    Vince:

    Couldn’t you have timed your experiment some time when I wasn’t sick with a cold? I missed most of the fun.

    Great job!

    From your list of things that didn´t work well, the most severe one that I can think of is the instability of the platform.

    Perhaps some extra lines from the legs could take care of that: http://wiki.seasteading.org/index.php/Image:800px-WaterWalker2VinceOnLand_extra_lines.JPG

    Yes, fixing the platform design is the big problem. The way you have the 4 extra ropes it would reduce sideways movement. However, even with those and the 8 ropes we had, the platform could still rotate. If we do ropes from corners to legs at 90 degrees we could keep it from rotating. But now we are at 16 ropes or more, not counting the safety rail. I am worried about the air drag from so many ropes.

    If we had a rigid square that sat on top of the pyramid we could widen the pyramid further and still be well above the water. So I am wondering about something along these lines. The problem is the legs can move a bit, so it has to be able to slide a bit as the legs move. The legs might have moved a couple feet. If we are connecting 2 feet down on a 20 foot leg the movement should be 1/10th as much, so maybe 2.4 inches.
