Work in this worksheet, replacing the values that are there (True Wind Speeds, True Wind Angles, Boatspeeds) with values that are germane for your boat. Paste these values into a blank xcel worksheet that you have opened and named as you wish (but the name should be readily associated with the name in step 1). Select all of the values in this text file (all row and column headings and entries in all cells) and copy them.ģ.
You may also elect to retain this new polar in a location other than the Expedition Data FolderĢ. Using "Save As", save this polar with a name that works for you or your boat. Open as a text file a set of polars for a boat similar to yours that you will find in Nick's polars that come with Expedition in the Expedition Data Folder / Polars. My polar creation method moves along these steps, which can probably be shortened or rendered simpler by a proficient user of PCs or xcel.ġ. Also, the US Sailing package is not really "crude" but has a lot of good stuff in it with which to create a heel polar and and refine your Leeway factor calibration in addition to Expedition-usable MH and 10M polars which need no scaling. I am not skilled enough to make the explanation concise and simple and I have found that the best instructional aid for me was Peter Isler's NorthU webinar tutorial.
