Target Boat Speed. Based upon the output of IMS Velocity Prediction Calculations, we've generated a graphical representation and a corresponding tabular data interpretation which illustrate the product of a series of equations applied to discover the interaction between variable forces of energy, inertia and friction in a hydrodynamic environment, for the purpose of determining their combined effect upon the velocity of a specific mass of engineered fiberglass, aluminum and fabric, with the final results expressed in nautical knots per hour.
(Editor's note: Pay no attention to that guy; he's been drinking too much cappaccino. Here's a chart and a pair of tables from J/Boats that tell you how fast your J/92 should be going, depending on true wind speed and sailing angle.)
On the following three pages, we didn't include any navigation buttons or links, so they'll print cleanly without clutter. Use your browser's "Back" button to find your way here again....
