Question:
The U.S. Navy has built the Sea Shadow, which is a small waterplane twin-hull (SWATH) ship whose object is to achieve the same reduced radar profile as the STEALTH aircraft. This catamaran is \(160 \mathrm{ft}\) long and its twin hulls have a draft of \(14 \mathrm{ft}\). Assume that the ocean turbulence triggers a fully turbulent boundary layer on the sides of each hull. Treat these as flat plate boundary layers and calculate the drag on the ship and the power required to overcome it as a function of speed. Plot the results for speeds from 5 to 13 knots.
