iPolar app for iPhone and iPad
Developer: KND Marine SOCIEDAD LIMITADA
First release : 08 Dec 2012
App size: 4.67 Mb
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.
Latest reviews of iPolar app for iPhone and iPad
hull speed is to high by 1 knot.
I really like this App. Ive owned it for about a year and the Oct 7 update provided some really nice features. The App was very accurate with my C&C99. The polars generated for my new C&C115 are a little slower than actual speeds observed in real life; the data is still useful nonetheless. I recommend you consider this App if you want an easy to use, adjustable, inexpensive mobile VPP for your racer/cruiser. I dont think theres anything that comes close to iPolar.
Its a good app but, imho , in the values table, along with the VT, must be shown on also the relative VMG. Would be appreciated also a print function.
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 dont 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!
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.
