Wow, I never expected to get so many replies!
As most of you have said, unless you need it for a commercial
ticket or similar, who really cares?
But then it is kind of fun to know.
So far, I haven't kept track, as I keep forgetting to write it in the log book and having quickly realised that the GPS grossly overestimates. So I have no idea what I have done so far. But I built a plugin on my blog that can import
the GPX track from OpenCPN
, so I think I will modify that a bit so that it adds up the miles from that.
That would achieve two goals:
1) no work (once i have tweaked the plugin)
2) gives a pretty accurate a-b but including around the headlands type of measurement.
Thanks for some fascinating reading!
