Hola Jim,
I see we may be passing through Tulla inbound on the same day...

moving right along...
never mind the semantics.. all that matters to the bloke on a boat in tidal waters is what the wind speed over the water is.... try taking a small boat up a creek in very light conditions... 2 or 3 knots of wind in the channel where the tide is on the ebb... nada on the flats... who gives rat's what is happening 300 metres away over the land... thats why the books are called 'Practical Navigation' ....

NOAA... not many practical navigators there I imagine.... US Military...Oh Ok...

Me? 51 years practical navigating in the real world ( 42 years in the day job) is all I can put my hand up for... nada mas...

You're right Jim.... I'm out of here.... cya

I suggest a read of this

http://sail-lbs.com/wp-content/uploa...1906435202.pdf

Would be in order for all ex colonials lol.

You will notice that " break " is not a recognised proword, this is specifically because it breaks the requirements of listening before transmitting

Dave
Thanks for the citation, I'll read it.

I was asking for a citation on military procedure not being used in Marine traffic.

I think you need to meet more Americans. All the colonials are long dead.

Re: Terminology ........ Whats your Flavour?

Ah, now for the "break" debate .
I am sure Dave is correct in relation to what is taught in his part of the world and his experience however that doesn't make it "the" standard in the rest of the world.

As others have said, the word "break" is taught as standard phraseology in aviation usage and I hear everyday in busy airport environments by none other than highly trained, highly skilled and highly professional Air Traffic Controllers. I would suggest the ATC environment is as good a standard as any for VHF communications procedure even if it doesn't appear in the GMDSS literature.

Over and out (opps... disregard....out).

Yes, of course. Thank you, I had forgotten that.
I just got so used to using the simple definition of ampere as the current flowing in the circuit with a PD of 1 volt and a resistance of 1 ohm that I forgot that it is a flow rate.


Still a useful term though when discussing battery capacities.

Surely it would be more like saying 'gallons per second per hour'.

How come compass variation hasn't got a mention in this thread yet.

NOAA, noted authority on all matters maritime, say its called 'magnetic declination' and only 'sometimes called magnetic variation' Magnetic Declination (Variation) Home

Only 'sometimes' called 'variation' by the entire global maritime fraternity since back in the dreamtime....

Oh hang on, this bit of NOAA doesn't even mention magnetic 'declination' ... The Compass Rose & Magnetic Variation

Looks like a left hand /right hand issue here.

Anyway I'm off ashore to buy a current bun to have with my 'onces'. Don't know if I'll chose an ampere or a humbolt...

Those that can....do
Those that can't.... teach
And those that can't teach teach teachers...

Sorry, but these are mathematical operations and there's a difference between multiplying and dividing.

5 Amps times 2 hours is 10 Ah.

5 miles in 2 hours is 2.5 mi/h.

Opps... Woty is wrong, red-faced and must remember to think before posting late at night. Thank you for the correction

Woty now returns to saying his tables.

And I do agree that ampere-hour is the correct terminology for stating a battery capacity.

Likewise.... who would have thunk that 'merkin english uses the term 'tidal current' but then these are the people that say 'left rudder' and 'right rudder' and have you ever heard them try and pronounce 'buoy'?

'Tidal current' is an expression you would never hear uttered by someone raised in the british nautical traditions and capable of speaking the Queen's english.

I shall continue to consider 'merkin english an alien tongue.

El Pinguino.... never wrong but quite often mistaken....
