Yachties Right of way

[rubberduck]

Back in the day an acquaintance had a similar contraption as a light box in his car. It got him into a number of scuffles and long explanations with the law.

The ability to shrug your shoulders, smile and walk away is lost to some people. Rise above it...

Agreed, however there was a SHB Boyne that was on my starboard bow and with his 5 knots closing on that turn to starboard track I may not have cleared him by the 100yds without slowing down (which I was also ready to do)

So altering to port means you missed him by 450 yards, altering to starboard you would have missed him by less than 100yds that suggests not altering at all you would have passed behind him by 100yds or so - perhaps he was happy with that distance.

If you were in fact going to pass close behind it makes it much harder for the yacht to give way as either reducing speed or altering course would make collision more likely.

Except vector triangles don’t necessarily work in that way...

Given the relative speed of the boats and assuming equal alteration in course in both cases it is a reasonable approximation.

Certainly strongly suggests that without any action the OP would have passed behind the yacht.

TBH I am not sure what else the yacht could have done.

Re: You want some Fred Drift ?

When is the When date ?

They want to know when we would like the measure to be introduced.
Ps. It requires legislation and HMG is tad busy at the moment.
PPs. To those who think we might keep the derogation after 31st, the gov is skint. matey

Pedant mode on: It would depend on the relative angles to each other of the course of the boats. At close to 90 degrees, your approximation might be close, but at more acute angles, it becomes very inaccurate. We don't know the relative course of the two craft. Why make assumptions?

If you are familiar with Portsmouth there is enough information in the original post to get the courses of both boats. The course from the main channel through the submarine barrier to Spit Elbow PHM is pretty much perpendicular to the entrance channel to the harbour along which the yacht as proceeding.

We do. It's not that far off 90 degrees where a straight line from the submarine barrier gap to Soton Water cuts across the main channel into Pompey. Within the accurac that you'd expect a yotty to judge the situation anyway.

But as I said in another thread, the tide stream will change the powerboats course a little as it leaves the shallow area near the submarine barrier. It's a matter of judgement... The question is perhaps whether the yotty might reasonably believe the motorboat is going to pass behind rather than whether it's actually true.

Bearing in mind that the most logical reason for the yotty, with or without his Breton cap, to be motoring up that channel is that he's come from France and is likely tired and might not be at his sharpest?

However, I do struggle with what to do about SUPs as I approach the somewhat narrow A27 bridge. I know I am constrained by my draft in a narrow channel, but not so sure they understand that, or indeed anything about IRPCS.

I've recently got into SUPing, and have been on the Hamble a couple of times with a group of slightly more experienced paddlers.

I'm pretty sure none of them have ever even heard of the colregs. However, their automatic assumption is that all boats have right of way and they need to get out of the way whenever one comes along. Think kids on bikes in a quiet residential street shouting "car coming!"

If any of the paddlers I know are getting in the way, it's more likely poor anticipation and lookout than an assumption about their rights.

Not sure SUPs are vessels in terms of colregs anyway?
Sometimes I feel its best to accord them the same 'rights' as swimmers...

It's certainly a grey area. When I'm on a paddleboard I don't try to stand on to anyone .

My sailing experience does give me an advantage compared to some other SUPers in anticipating what boats are likely to do and what action from me is likely to be most helpful.

I read the OP with difficulty.
In everyday parlance (nautical or otherwise) k is an abbreviation for kilo or thousand.
Then 'c' - what was that? After trying to make sense of the OP I guessed it was the OP's private abbreviation for cable.
He/she is entitled to use any odd abbreviation they wish, but they should tell us when they differ from standard.

Surely the OP would have spotted the string of onions around his neck and the blue smoke from his Gauloise and altered course accordingly?

Where I am coming from:

At the weekend in Chichester I was suddenly surrounded by dingys in a race in a narrower channel at a low tide and spent more time going astern than ahead. The rules still apply.

Point of order: if you met the XOD fleet in Chichester harbour you would be forgiven for thinking that the only rule that actually applies is that everyone else is in the wrong.

May be simply familarity but I and obviously at least some others, knew that c meant cable, and that a cable is 1/10th of a Nm, 608 feet, 200 yards or so, although you do have a point. My 5011 includes the cable as a unit of distance, but states no abbreviation for it.

Point taken

For what it's worth, I read it as "cable" without any difficulty.

Thought the correct abbreviation for cable was "ca".
