Plenty of room for logic chopping here! But doesn't reasonable apprehension only come into it if the apprehensive actually takes action as a result of the apprehension? If I have reasonable apprehension that port will not succeed in crossing, and duck or slow, then port is penalised. But if I have that apprehension, but hold my course, and in the event port crosses by a reasonable margin, i don't think port gets a penalty. There are shades of meaning here. "As a result of my apprehension I felt compelled to take avoiding action" is not as strong as "with collision imminent I was compelled to take action ..." and does require have a sense of external influence as in "with collision imminent I was required by RRS14 to take action ..." ?

Yes I know that I was stretching it I’m a J24 with 4 crew facing out.  But in a sitting out dinghy?  Helm and crew can’t have eyes in the back of their head

And I appreciate it.

I never called you a blockhead.
