    Title says it all. It’s probably been suggested before but I couldn’t find it in the forum search.

    Adjacent seasteads may move relative to each other, making bridges potentially unpractical. A bridge can have some degrees of freedom, and the more still the seasteads are relative to each other, the easier it is to build bridges. However, it’s relatively straightforward to build aerial lifts, and let’s face it, they have a cool factor.

    In order to accommodate for varying distance, the cable can be tied to spring or much better a counterweight via a set of compound pulleys so the counterweight doesn’t need to be too heavy. I drew the spring instead of the pulleys because I can’t draw and pulleys were much harder to draw, but pulleys+counterweight are definitely the way to go.

    There is a modified version of the a ‘Beeches Buoy’ system. It would only work if the Seasteads were anchored 180′ out from each other otherwise they would slowly be pulled together… It would work though.

    Would not need to be anchored. If you have something that can move you through the water it can also provide tension on the line after it is connected between the two seasteads.

    The U.S. Navy used moveable bridges between barges. It has fairly low wave height limits though, even in scaled-up form. I can’t find the original reference which had pictures of the bridges, but here’s a related link.

    If the cars move suspended on a cable, there will be a tendancy to both tip and pull the spars tward each other. OTOH, if you use a rigid rail that’s mounted of rollers at either or both ends, that need not be true. That would then function more like a gangplank than a breeches bouy.
