Following the post called “Boat characteristics and learning to wally!” I had a number of mails about polar diagrams see also the comments to that post from Peter Gustafsson.
I can confirm that MaxSea TZ does have a comprehensive polar diagram creation option. It does not assume that the port and starboard speeds are symetrical (like some software). And you can create the diagram automatically
You can also store diagrams according to differing sail sets that you are likely to use.
