Very handy in open water ??

Wow... I didn’t know that!.....

 

[Bouba]

I should rephrase that...I do not mean that I don’t know how to avoid a collision...

 

[capnsensible]

Is there any sound?

I'm guessing they are talking about steady bearing on a shore feature?

That looks like Cork Harbour, as there are only two tall blocks.

What if you used this building as your marker....

For those that can't open it, can anyone explain what it's about?

Ta.

Well that thing you do automatically with just your eye.....it complicates it

I told Bernard Cribbins that he had put it in the wrong place ?

It doesn't just complicate it, it's plain wrong. He's got himself confused with "taking a bearing from a fixed object" and "vessel B being on a fixed (ie constant) bearing".

If vessel B, between you and the fixed object, is stationary in relation to the fixed object then you are overtaking it on a parallel course - I scribbled a little sketch with vessel A travelling at twice the speed of vessel B:

What a disappointing video! As soon as I realised what it was about, I spent the whole remainder of it braced for the big CRASH!

 

[creeks]

.....now which mast and which chimney did I take that bearing from.....

Not I. I recognised the tone and delivery of a competent ISA Powerboat Instructor?

The trick really works, BUT:
1- both boats are supposed to keep speed and heading constant.
2 - what exactly predicts a collision is the steady constance of the other boat bearing, e.g. by a sighting/aiming compass. Using a mark on land is a practical expedient that is acceptable only if the land is so far away that the mark bearing is not changing much during the watching period.

Strong tidal streams don’t help either.

It is not Cork harbour. Any way, boats do not keep a steady course in Cork Harbour...unless adrift??

Been using this for over half a century. Thought everyone knew this. I was the tactical caller whilst racing for port and starboard decisions and talking to the helm if on port tack to ensure we either passed ahead or had to duck down slightly to just miss the transom. Used to get it very accurate and most other boats hated how close we passed by them and frequently kept clear of us for this reason, which made out lives even easier to maximise boat speed.

Eat a raw, live mollusc? No thanks, a vile thought but each to their own?

You guessed correctly
