Course to steer for crossing the channel

One more thing. The tides down the back of the island have significant North-South components so there is a lot to be gained by going with them. If I was you I would do my best to be at Bembridge Ledge an hour or two before HW Portsmouth on the way out. The ebb then gives you a hearty shove to the SW.
 
I've also used it to figure whether my course across the Channel would venture into the exclusion zone around a central cardinal mark..

Is the central Channel cardinal mark (a lanby I think) still there? I can't find it on the Memory-map chart - just at "seasonal" yellow buoy at 50.20.34N, 1.29.12W

Well, that's a really good question - I can't find it either! There used to be one called 'EC2', I think.

OK, a quick search shows [ http://www.ybw.com/forums/showthread.php?8901-EC2-BUOY ] that it's been gone for many years! I only updated my Channel charts last year; I guess the previous ones still had it marked. And there was me worrying about my 'S' curve washing me into a non-existent exclusion zone! Thank you.

Well, actually....

Whilst the buoy has (I believe) gone, I think the Area to be Avoided is still shown on the charts. I don't have the latest paper charts for that area, but it is still there on the set I do have (minus the buoy).

Hilarious.

I couldn't find that Area to be Avoided on Navionics WebApp this afternoon. It used to be somewhere roughly between the IoW and Cherbourg?

Well, I will admit to having passed through it a few times*. I wasn't arrested or struck by lightning, so I doubt you will be either.

I don't have the charts in front of me, but the interweb says EC2 was at 50 deg 12 N, 1 deg 12 W - 40 nm NE of Cap de la Hague.

* not deliberately, I might add. At that point in the channel, I am usually fairly well zoomed out with the chartplotter. The Area to be Avoided only shows up when I zoom well in. So, I usually only realise that is what I have done when looking at the tracks on my plotter from previous trips.

Crossing the Channel and finding Cherbourg is easy enough. I usually find that the difficult bit starts when I get to the entrance in the dark and try to find the lights for the inner rade against all the other lights. These days my route takes me to a WP at the inner rade and marina entrance.
 
Normal Merchant Navy practice is ( or at least was in the 1980’s when I was a navigating officer) to keep the ship on the course plotted on the chart. Crossing an ocean that meant daily alterations of course to allow the ship to sail a great circle course (straight line plotted on ocean chart).

When coastal with tide factors course alterations would be made every hour maybe to keep on the plotted track. My old Captain would have hung me up by my dangly bits if I had been off the plotted course following a S curve. I still follow that approach today, maybe not as efficient but safer because I am on the track I have plotted and checked to be free from danger.

Good grief: you either haven't been reading, or understanding, this thread have you?

As has been mentioned several times, by several contributors, you obviously do not just blindly follow the S-curve.

It is essential to check beforehand that it is safe to do so: but when it IS safe (as on many cross channel passages), then it IS unarguably more efficient, and arguably more seamanlike.

Which is what I was trying to say at post#32. Keep your head down now Dutch!

Ok ... it must be me who is missing something.

Can you please explain why you need to stick to a line drawn on your chart, if you have diligently checked that there are no dangers within a safe distance either side of that line?

Please explain why, in a small, slow, boat, you advocate making a passage longer than it need be?

I'm beginning to think that the only reason is that it is simply unquestioning acceptance of what was ingrained into you, and then enforced by fairly strict discipline.

It seems to me to have absolutely nothing to do with being a thinking, prudent, navigator.

But I'll be very grateful if you can convince me otherwise.

I’ll have a go, but will have to agree to disagree I think in the end.
Navigation is determining where your vessel is and where it will be in the future.
Following a pre determined nav track allows this.
Steering a set course and allowing the tide and wind to move you, then plotting a historic position is not.
I am prepared to accept that in a slow moving boat crossing at right angles to a varying tidal stream direction is more efficient in time.
But my experience has been different to yours obviously, and I prefer to know exactly where I am and where I will be in future.
Navigating through the Solent at 30 kn at night doesn’t allow for error in position.
Drifting across the channel to Cherbourg at 5kn, I could live with your S curve stuff.
Obviously Dutch and I had similar Captains!

Tonight’s toast to you all “A bloody war or a sickly season”

Historically, If you were in charge of a warship, it would have made a lot of sense running down the same line every time you go from A to B. The chance of hitting an unchartered rock becomes vanishingly small once you have done the same route a few hundred times.

As we know, if you hit a rock, or run a submarine into a beach, it is a severely career limiting move..... or maybe not. :o
