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.
