boat tails

Think canoe,kayak.And your correct,America's Cup yachts use an International Canoe Hull.Catamarans,bingo! Also Yale racing sculls,sweeps.Torpedoes,submarines.The last 15% of a hull can be chopped off without alot of form drag increase and the skin-friction drag reduction is significant,since water is over 800 times more dense than air and much more viscous.Remove the tail from a wing and drag goes up 900 %.
