    I too was wondering what it must be like to have to steer a ship without being able to see a thing. All that telegraph business also seems very clonky. It last for years, so I imagine that nobody could think of a better way of doing things. I wonder if I would have been guilty of 'chasing the lubber line'?

    Larry I meant to show you the link. As I pointed out steering on a survey wavering off a meridian more than .0000 of a minute is … well … words fail me. Here's an example of Larry's steering down a meridian:

    Words fail me. A ten thousands of a minute is 4.16inches. He wandered a foot. A FOOT!

    And your counting Larry! It's 3 plotters not two. It's serious business this survey stuff.

    Hey listen chaps. Using Navionics (briefly, very briefly) we found in a square n.mile, two buoys missing, another buoy in the wrong place (half a mile out) and the soundings way out. Why would ever use Navionics if you didn't know where you were going?

    Oh PS: New chartlet of the Little Sunk crossing point is now posted: http://www.crossingthethamesestuary.com/page37.html

    I bet I would have chased the lubber line. I reckon in that small room with no horizon etc could be very easy to disorientate. And I am not sure I would have been happy in the steering position in the Battleship. Might be safe but if the ship was sinking, you ain't going to go out. Mind you on the destroyer I guess the enemy would be aiming at the wheelhouse! Eek.

    blimey - were the buoys out of place or is it that the Navionics chart wasn't up to date? Had it been updated ('cos they should update online in real time now...)?

    The buoys were and are in place - and have been for years and years. And the Navionic chart was up 'to date'. On the 3rd this month and today, a user(s) has reported two of them. The point is that Navionics cannot be trusted. There are quite a few 'User Reports' going back to 2013 and 2017 elsewhere. They might have been right then, they aren't now. My experience of a plotter is very limited of course. But it certainly isn't an old chart as because the errors have never been there. Appalling I think.

    Ahh, I love those videos.

    A great memory I have is my first skipper on a trawler when I was 16yrs old and I was a sponge for information turned off the autopilot and gave me the helm. We had Decca but I was learning that so he gave me a course to steer, I was swinging the wheel frantically from left to right trying to keep exactly on it. He said I was trying too hard. As far as I remember on that boat there was 14 1/4 turns on that wheel from P to S. When I was 17yrs old I was able to take a 73ft, (ahem, Reg 69.9ft so we could fish up the Clyde) boat in through any harbour. No bow thrusters or anything like that.

    I just did the NauticEd Rules of Prevention
    of Collision at Sea. I hope you guys have a look at it.

    There was a thread here a while back about sailing boats and fishing boats and who has the right of way. I recommend it and also it's free. I'll be honest, I got 90% in the test at the end but I'm new to sailing rules so S tack against P tack got me.
