    Excerpts from the Tech. Articles:

    Speed and Powering Update
    "David Wyman has written me with improved calculations for determining the Wyman coefficient. These make his already excellent approach still more accurate. The overall Wyman speed-and-powering formula is unchanged; this is just tweaking the coefficient to get still more precise results. The revised coefficient can also be read from the graph. You will find the above adjustment to the Wyman coefficient puts your results even closer to dead on target than the version presented in the previous issue."

    Conducting Speed Trials
    "In order to fully evaluate the performance of your Swift 'n Swanky--or any other boat for that matter--you need to systematically test its performance and behavior; you have to run sea trials. Indeed, this is exactly what any commercial operator or naval crew does every single time they take delivery on a new vessel. Proper sea trials for a ship may take several weeks of careful painstaking work. What's more, many of these trials will be repeated again at regular intervals over the life of the vessel--after major overhauls and refits, or simply when a new captain takes charge. Sea trials are not just informative but provide critical information for evaluating your design, applying this data to future design work, and providing valuable information to the crew on performance and range."
