Get,
This is why the COLREGS have Rules of the Road & these differ by location.
Also, I do not see which area you sail in.
The downside is, nothing is concrete in the Rules. It's more or less subjective to situations & the rules can change depending on location. Western River Rules differ somewhat from other areas.
Are you a vessel up-bound bound or, a down-bound vessel & is there an upbound or downbound current? Are you under inland rules/coastal or international? There are different rules for these meeting/overtaking & crossing situations & the type of channels. Knowing which applies can make a BIG difference in your setup course.
The rule of thumb is, that the overtaking vessel has to give right of way.
Then there is the "Pecking Order" based on size/type & what the boat is engaged in. Then, let's add submarines, seaplanes & less than 16 footers and then, the rules can also differ by day-n-night.
Do you see where the rules can be in a grey area inland vs. coastal/international & vice-versa? For you, the overtaking boat should NOT have impeded your course however, location rules can be somewhat confusing.
Look up the COLREGS for your area & see a 360° view of how it all fits together for you pal. I myself, have a COLREG copy on my boat for several areas & reference these just to make sure.
The downside I see is that, if the other guy doesn't know the rules..........
then.........., do the rules apply or, is it now just every man for himself at this juncture?
Herein lies the conundrum & the the GREY AREA I spoke of.
