One hull or two? Max and Brian race model sailboats to find out which boat is the fastest.
Max and Brian love to go sailing, whether it’s on 15-foot boats or with model sailboats. Our investigators head over to the California Science Center with their model boats to answer the question: Which kind of boat sails faster, a single-hull or a double hull boat? It all comes down to sail size, overall weight, and amount of surface touching the water. Can you figure out which one will win?
