So, how would you decide that the line is biased or perhaps where the windward mark is 1nm away in choppy conditions? Or perhaps Championship event RO’s give the course vector in..ohh.. hand signals or smoke or maybe shine a light on it.
RTC short course racing is easily done without a compass, if you know the course and where the marks are. Add in an Open Meeting where competitors new to the water are racing and the RO will always give a compass vector to the windward mark.
You’ve no need to pick up on anything I’ve mentioned, I’ve ran Olympic Qualifiers and all sorts of World Champs as RO. Raced RORC events for the last 25 years (won loads), multiple World Champs in Small and Big boats, including 7 ARC’s..
But hey, the RYA Day Skipper onshore course page two outlines what a compass is, and how to use it.
Blah, di..blah.
