I think we can sum this up by saying that:

Roger was probably in the right as far as Colregs and right of way was
concerned.

Single handing demands some effort to think ahead and does not grant you
any special status.

The discussion that has evolved is the requirement to have/use VHF.
That is a good topic.

I don't think that VHF radios are required on small pleasure craft but I
wonder why everybody wouldn't have one as a basic safety onboard safety
item?

Furthermore, if one is onboard why wouldn't you make best use of it as
required by the Colregs?

(I interpret the rules to say that if you have one you must use it.
Just like radar etc. "all available means")
