The document discusses the design and physics of a boat created by a team of students for an assignment. It includes sections written by different students on the boat design, physics calculations, keel forces, and sail forces. The team designed a multihull boat with movable sails and blocks for keels. They calculated that the boat force is 7,408.8 N, gravity force is 11,136.12 N for the 1,136.12 kg boat, and with 10.6 mph winds the sail force would be 24.6 N.
