course deviation in stormy weather?

Lomaster · 07-13-23, 01:46 AM

Can the boats course change without any input from player? I had an unpleasant situation yesterday. I play TwoS with real navigation (nav marks off, everything off. Using dead reckoning and celestial fixes and writing a real pencil paper journal) My last dead reckoning was at september 2nd 1939 at 19:20 some 15km south of Bornholm island. I set my course to 280 and set an alarm clock at 7:30 next morning, expecting Falsterbo Peninsula to be visible by then. It was a stormy night with gusts of wind as strong as 16m/s. When alarm clock rang i still could not see Falsterbo Peninsula. In fact i could see some land mass far away to the south. Completely puzzled - i stopped the machine and calculated my latitude, which deviated from my estimated latitude by whopping 35' to the south (70km in SH5). Then i noticed my course to be 258. I checked the ingame journal (see the screenshots) As you can see, after i set the course to 280 it does not say "new course" anywhere, BUT at 3:00 an automatic report by Sturman revealed the course to be 260!!

Was it caused by the storm? As i mentioned above the course deviated further and by 7:30 it was 258 degrees.

This is quite possible, even if your deviation of more than 20° is very large. In storms and strong winds, I usually have a deviation of up to 5°, which I usually correlate and adjust every hour.
