3. INTRODUCTION
“esa Data & Polar Analyzer”, IN AN EASY AND AUTOMATIC WAY PROVIDES ALL NECESSARY DATA
TO THE COMPREHENSION OF PERFORMANCES AND OF THE NAVIGATION DONE.
It is always possible in a total automatic way, to import performances’ files generated by esa, and analyze
them with respect to set up tgt's file, both in correlation to full polar run, respect to WMG, and other
navigation recorded with your Apple’s device.
Importing file is very easy, is like to open a file in windows, and the program automatically does all the
calculations, giving you the results both graphically and in numbers.
Through the different pages of the program is possible to make the following analysis:
• Esa polar data calculated with respect to set tgt yard polar.
• Graphical comparison analysis of polar data calculated by esa and set yard polar.
• VMG analysis, sheet where are graphically compared boat speed, TWA and WMG respect to
yard’s respective.
• Logging, sheet for telemetric analysis of navigation data, you can display regatta or navigation
route, (even with Google Maps), and analyze the performances.
• Start procedure, sheet for telemetric analysis of starting data, both visual and analytic analysis of
starting moments.
• One data sheet.
• Possibilities for further analysis, due to Excel customizability.

4. ‘GENERAL’ (OPENING SHEET)
First page is where to upload files by selecting the buttons at the top and where is possible to make a
comparison between numerical numbers of yard polar and those of esa’s (after interpolation analysis, see
attachment n.1)
Uploading file is possible after saving them on the pc (via iTunes), it’s very easy, like opening a file in
windows.
It’s possible to choose the number of columns.

5. ‘GRAPHICAL ANALYSIS’
Once uploaded all data in the previous page, is possible to compare the yard polar curve with the point
calculated by esa, by selecting the different wind range for any direction.
And all these functionalities are all automatic!! Is not necessary doing any analysis, and without any loss of
time!!
pag 5

6. ‘VMG ANALYSIS’
Fundamental analysis for stick regatta, the only in the word able to provide real time results!!
The program automatically elaborates the comparison between target data obtained from yard polar with the
values calculated by esa during navigations; the comparison is possible for TWA tgt, Bs tgt and VMG, in
bowline and stern, also distinguishable between starboard and port tack.
Here below an example for the bowline, where is noticeable a small performance difference between target
(as actually happened in reality)
Thoroughness of collected data has been certified by several compared analysis with the help of professional sailors.
Values’ sweep depends in this case from the scarcity of collected data ( 4 stick regatta).

7. VMG ANALYSIS: APPLICATION IN SPEED TESTS.
Example of one of the test done at the end of a regatta, which compares two different kinds of bows’ sail
obtaining meaningful data with only 30 minutes trial time.

8. ‘LOGGING’ (RECORDED DATA LOG ANALYSIS)
It’s always possible upload automatically one or more log file and do an both visual and analytical analysis.
(see two quadrant on the left); moving the cursor in the center data are analyzed and shown on the left. The
arrows show wind direction.
You can do debriefing or see your navigation immediately.
pag 8

9. ‘START PROCEDURE’ (PRESTART DATA – UNTIL ONE MINUTE AFTER THE START)
It’s always possible upload automatically one start file, and do an both visual and analytical analysis. (see
two quadrants on the left); moving the cursor in the center, data are analyzed and shown on the left. The
arrows show wind direction.
You can do debriefing or see your start immediately.

10. HOW TO EXTRACT DATA FROM IPHONE, IPOD, IPAD
There’s an extremely practice way to extract data’s folders via iTunes; from them you have to choose each
time which file to upload in the analysis.
Select the device in iTunes, go to app section, select esa Regatta and the four folder to be saved, save them
anywhere you prefer, at this point you can use data for the analysis.

11. ATTACHMENT 1: PROGRAM ACCESS AND MACRO ACTIVATION (1/8)
The disposable program on the site is made by 2 files:
PolarAnalysis.xls (the main file of the program)
• XlXtrFun.xll (library file which contains the interpolation functions to change the yard data and polar
in Esa polar format)
• LICENSE FILE IS MISSING. IT WILL BE GIVEN ONCE THE PUSHCHARGE HAS BEEN
COMPLETED
• At the opening of the program let macros run
• NOTE FOR EACH PC AT THE FIRST ACCESS LE LICENCE IS NECESSARY (MAX 3 LICENSE FOR
EACH PUSHCHARGE. See next page
Select:
- Options button
- Activate content for macro
pag 11

12. ATTACHMENT 1: CREATION OF LICENSE FILE (2/8)
• FOR EACH PC AT THE FIRST ACCESS:
IT IS SHOWN A CODE NUMBER TO BE SENT AD THE EMAIL DISPLAYED
• You will receive, after the puscharge: License.dat (license file for the program)
insert it in the same folder of the program and XLXtrfun
• Last two file have to be in the same folder of PolarAnalysis.xls in order to run it properly.

14. ATTACHMENT 1: PROGRAM’S INSTRUCTION IN EXCEL (4/8)
PolarAnalysis.xls is made by 6 Excel’s sheets.
• General (sheet where to start all the analysis)
• Graphical analysis. (in this sheet are analyzed the acquired polars during navigation and they
are compared with yard’s target data.
• VMG analysis (sheet where is made a graphical comparison between boat speed, TWA and
VMG data respectively with yard’s data.
• Data (support sheet, are uploaded here all esa and yard polar’s data).
• Logging (sheet for the analysis of one or more navigations with Google maps visualization)
• Start Procedure (sheet with path and related data to start procedure; map visualization).
pag 14

15. ATTACHMENT 1: PROGRAM’S INSTRUCTION IN EXCEL (5/8)
From General sheet is possible to start all the analysis, only telemetry analysis is possible to be managed
from Logging and Start procedure sheets.
It’s necessary to access in the folders uploaded via iTunes (see pg 10)
Files uploaded from
iTunes by connecting
the device
In general sheet we find these buttons:
“Load Polar Files”, by selecting it uploads polar’s data file which contains both yard’s and esa’s data
acquired during navigation. All these data are saved in “data” sheet.
File to select
pag 15

16. ATTACHMENT 1: PROGRAM’S INSTRUCTION IN EXCEL (6/8)
Graphical analysis compares navigation data with yard’s target. It’s possible that for some wind intensity
are not enough or invalid data. In these case the program says to the user that all polar’s selected values
are null. (see also pg. 5)
VMG Analysis. Even for this analysis is necessary upload before a polarEsa file…
VMG analysis compares yard’s polar data (Boat Speed, True Wind Angle, Vmg) whit polar data (left and
right handled). It is possible upload more Esa polar file at the same time, or selecting together in order to
obtain a better VMG from those different files.
Files to select
pag 16

17. ATTACHMENT 1: PROGRAM’S INSTRUCTION IN EXCEL (7/8)
“Load polar file”. Pressing this button Esa polar data file is loaded, in which there are both yard polar data
and those acquired during navigation by Esa. These data are saved in Data sheet.
In Logging sheet there are:
• A dashboard where are displayed several navigation data.
• A 2d map, where is shown the path of the boat. With the underneath bar is possible to run along all the
path and analyze second by second the data in the dashboard.
• Path is displayed in Google Maps, with “Refresh Google Maps” you refresh the map, in particular the
positioning of the boat; with “Zoom +” and “Zoom –“ you change the dimension of the map, with the
button on the extreme right you can change the kind of the map.
• There’s an arrow which displays wind provenience at the considered moment.
Selected Files
By selecting more than one file, ESA will
show a sum of the selected logs.
Very Important:
Once the program PolarAnalysis.xls is closed, all data will be lost, and at the sequent re opening is
necessary re-load all data for doing analysis.

18. ATTACHMENT 1: PROGRAM’S INSTRUCTION IN EXCEL (8/8)
“Load start data”. Pressing this button Esa polar data file is loaded, in which there are both yard polar
data and those acquired during navigation by Esa. These data are saved in Data sheet. The functionalities
are similar to those in Logging sheet, data in the dashboard are mainly referred to time and distances
during the countdown and the minute after the start.
With two arrows are indicated the provenience of the wind and the North.
Files to be selected
Very Important:
Once the program PolarAnalysis.xls is closed, all data will be lost, and at the sequent re opening is
necessary re-load all data for doing analysis.
