OOOOOOH. Is the emphasis correct??
I see you are looking at this. so..........
at six miles. (with the inherent error of RRP, AND human interpolation)
is 1.5 miles acceptable?
Is the yacht even able to compute this measurement?
Is this acceptable in 12' seas?
Add to this the yacht crew fatigue. and affects from the seaway.
Or.......... to ensure a safe passage
should the yacht just alter course 10 degrees ........... for 15 minutes....... to ensure a greater CPA. ?????
I am not going to enter your discourse about whether to 'run away' from your voyage. But I will enter the discussion about staying alive.
I used a card, with stipplings on the edge to make the lengths used in my pics. I carefully measure my one mile, two mile, an (most importantly) .6 mile marks. Maybe the pics distort. Maybe the images
are rough. (sorry, I am just an ordinary sailor like Y'all) But, this is what I expect when I am on a yacht on a bouncing, tipsey, rounded chart table. But, the concept
is fairly accurate (as far as the original poster made the claim about how "Freighters Vs Sailboats" is concerned,
You GET it. Why argue? The semantics are irrelevant.
I pointed out your earlier post. It was an INCOMPLETE post. Yet you stand by it. When you speak in "absolutes" you must make sure that every (and i mean every one) situation in covered.
Maybe your interpretation of: "fine on the bow" is between 30 degrees either way. That would be a huge 'teaching' example. ( I don't agree)
