Boating with Plywood

Our friend grew up in Wisconsin where when they get bored with waterskiing they cut a sheet of plywood into a disk shape and get onto it to be pulled behind the motorboat. Additional props are necessary, such as the resin chair shown in the photo above. Each of the three participants in the plywood derby this weekend went into the water with disk and chair and two of the three managed not only to sit on the chair on the disk while being pulled behind the motorboat, but stood up on the chair on the disk and then turned around backwards, while continuing to be pulled along behind the motorboat.
