Beschreibung

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.

Works as advertised.

Simple and from what I can tell about how our boat sail, close to what we actually see. For the price thought I would really like to see a little more data input ability to fine tune the numbers a bit more. All in still good, at least for now.

Zero stars...

This app is terrible. It simply creates a polar based on LOA, LWL, Disp, and Sail Area. This has nothing to do with creating Polars via actual sailing. This is useless.

Excellent ease of polar construction

So, it is winter, but I thought, "What the heck", and bought this. I was instantly impressed. The calculation was pretty much spot on to my existing polars. I don't update everytime I am out, but with this and the ability to set a percentage of efficiency, it is going to be in my top 5 best "friend" apps. The ability to export into Weather4D Pro and optimize routes is great! The fact that is an iOS app and is intuitive out of the box just adds to my fondness of it. Since everyone I sail with either has an iPhone or iPad or both, I just have to show them once how to use it and they can then tweak it without bothering me while I am off shift. I am also seeing how I can take this with me when racing with others and help to improve their boats. The only thing I wish I could do is print my chart. While it is super elegant on the iPad, sometimes you want a printout in a page protector that can be stuffed in a pocket. Yes, I could install on my iPhone, but paper sometimes is just better on a boat. Otherwise, this is great!
