12月9日的iPolar应用程序分析

iPolar generates sailing yachts polars of cruising yachts and cruiser racers from a very simple set of data. iPolar is fully functional on iPad, iPhone & iPod touch. Mandatory Input data: - Length Overall - Displacement - Mainsail area - Jib area (units can be set to metric or imperial) Optional data: - Length Waterline - Symmetrical Spinnaker area - Assymetrical spinnaker aera For each sail configuration in the input data, iPolars will compute a performance polar decribing the yacht performance in kts for wind strength ranging from 4 to 30kts and true wind angles ranging from 0° to 180° Output format: Resulting polars can be visualized as a graph and as a table of numbers within iPolar. In addition, the polars can be sent directly to the weather/routing application Weather4D Pro. Limitations: iPolar has been developed to generate accurate polars of cruising yachts. It currently does not handle multihulls and is limited to yachts with a size ranging from 8 to 20m. The accuracy of the application decreases for yachts whose displacement to length and sail area to displacement ratios are outside the usual range for production cruisers and cruiser racers.
