This multispar has 4 pipes each with its own ballast that are loosely connected to a platform. This is a bit like Versa Buoy. There are 4 legs of 4.5 feet each of 2 inch pipe. The X-shape platform is 1-inch pipe with each piece 1.5 feet long. Elastic cords connect the 4 legs to the platform. Each elastic cord has a knot inside the cap and also a knot on top of the platform pipe. So the legs are held to the platform but they can flex. There is a small balsa wood platform held on with rubber bands. The cup has a thumb tack inside it holding it to the balsa wood.

Tried 2.5 lbs steel weights from a weight set and these were too small, the legs floated out. Then tried 5 lbs steel weights and it floated too low in the water (picture above). It was very stable, just that the platform was hit by some waves. Plan is to use sand in plastic bags so that we can adjust the amount of weight used till it is right.
