    Dear Tom, I’m so happy to hear you talk about the essential things in life( on board a ship) 50 years ago when I was studying for the merchant marine we knew how to analog our way through the world. Do these “new” seafarers now about the old ways? If not, they’re f…d when there digital shit goes overboard. In my humble opinion it really is all about seamanship. Thank you for you sharing your wisdom!

    I bought a Walker log last year - a "modern" one (circa 1980, a Knotmaster MkIII A) - just to mess about with analogue instruments to get back into the habit of mental dead-reckoning. Next on my wishlist is a half-decent sextant!

    I love this
    In 1986 we were sailing from the Pacific Northwest to Hawaii
    Sextant only of course
    There were 4 of aboard and for all our 1st time offshore
    It was a beautiful day, the boat sailing along on a reach and the monitor vane doing such a great job there was little to do but enjoy the ride at that moment
    The skipper came bounding out of the cabin and half panicked declared that we don't know where we are, which more or less may have been true
    All I could think is that it had only been a week and was totally relaxed about it
    We really didn't need to know where we were yet
    On a 3 week passage if it had been a month or more I might have been concerned
    We made it to Hawaii in 22 Days

    Enjoy you tales and yarns Tom. I come from an even more ancient era and now too old to go sailing and as well the body is falling apart. Very envious of the new wave of young adventurers with all the modern IT, GPS etc. and gadgets making it all too easy. The opportunity was too rare and difficult in my youth. However to add to the 'exact knowing where you' are is the use of satellite pictures and charts, as well as sending out a radio controlled drone to check out reefs and passages in especially difficult locations in the Pacific, otherwise not visible from the mast ladder view point [difficult if sailing short handed].

    @johncollymore1697 4 роки тому +2

    Such entertaining and enthusiastic commentary from an experienced seafarer - keep up the great work Tom! On all your thousands of nautical miles sailed, how often have you lost the 'impellor' of your Walker Log - perhaps eaten by a fish - does that happen, or is it an urban myth! And secondly, a Walker Log normally stays with a boat, or is part of her gear - how did this one end up in your shed, which vessel did it come from, the old pilot cutter 'Hirta' maybe, perhaps when she was re-fitted with a 'thru-hull' log...? Cheers.

    • @TomCunliffeYachtsandYarns
      @TomCunliffeYachtsandYarns  4 роки тому +2

      Good questions John. In the early days the impellers were shiny and the tropical fish loved them. I lost a couple I think. Always suspected large pelagic predators too big to take my lure. Then they brought out the black ones and they are definitely not so tempting! This particular log has been around a long time. I kept in on Westernman (40ft gaff cutter built for me in N America) whose through-hull log was never any good, but hung onto it when she went on from me. I think the new owner probably sorted the electric one. Tom

    A deep sea capt once advised/said to me; the worst seas he ever encountered were on the Great Lakes and more importantly , the instrument he trusted on board ship more than any other was the ships RADAR. Twice in 10 years I have been lucky enough to use it myself "in anger'' , oh-so-grateful to locate river entrance groins poking seaward from shallowing featureless shorelines after my distance was all run and in bad haze visibility.

    • @TomCunliffeYachtsandYarns

    Exactly Tom! I think a DR plot on a chart is important, even with the new GPS. I found that some GPS chart plotters did Not match with paper charts and hand bearing readings in the islands of Belize. The paper charts were based on 100 year old surveys. The GPS chart plotter said we were pin dry land. But in reality not.

    This is so important to know and so well put together it gave me goosebumps! In a new ECN chart you can right click and find the CatZoc (Category Zones of Confidence) and also the date and method used for the survey. In North America you can find 1948 and lead line quite often! Also the Hdop of the GPS is often ignored. When you have only 3 satellites in a cluster with the same inclination and azimut you can easily get an (un)precision of 100 meters!

    Very true, Tom. I was using a GPS for a land survey back in 2001 and was puzzled by the lack of correspondence with the map, an error of at least 50 metres in the E-W direction was apparent. I tried to ring people I thought might be able to check out their GPS units, as I was convinced it must be the US Navy doing something, but no luck. The next day the error had grown larger and now I was beginning to suspect my GPS unit. One day later and the error was about 200 miles! I tried resetting it and downloading the latest firmware but the error persisted. It was still good for speeds and a few other functions, but positioning was gone. Brought it back to the outdoors shop where I had bought it, and it was expensive too, but the "expert" just switched it on and said "it works, what's your problem!" Cretins....

    I have a little chuckle every time we get a water bill from a chap who comes round and reads the meter at our front gate in Thailand. His machine prints out the bill which includes the Lat and Long of the meter to 6 decimal places, and I think of the little hand-held Garmin which got me around the south coast of England and across the Channel. They used to say you couldn't rely on that to be within 100 yards, but it was fine for me, and a lot better than the Dinghy Decca which it replaced, and than my dead reckoning, which was rubbish.

    And someone may have driven a 2CV into the water since the last survey. I’m suspicious even of the Navionics charts updated by boaters recent sonar observations. I wonder if they always calibrate correctly for the depth of their transponders. I hear there are still lots of drunken matelots, even on the Texas waters I go out on very intermittently. My favorite story though, is on the risks of too much accuracy. I hear at least one alleged mariner decided to use the locations of center channel buoys as waypoints. Of course they rammed the first one.

    Tom your turning into a true confession channel.
    In 1979 the Xxxxx Star was heading south by west a half west. My watch ended and I advised the next keeper that I put the sounder on as sun and celestial positioning was uncertain for the past three days. During my drowsy sleep I was put hard agains my bulkhead wall as the vessel canted hard to port. at 18 kts it was something of a manoeuvre. All the crew off watch would have been awake in their bunks, like me.
    All settled to a relaxed and regular thud.
    Next watch we were seen to have A/C because we had been 50 miles further west after 4000 miles since the canaries. Well done BritishMerchant Navy training and well done **** Star marine management for predicting the unexpected.

    As to that Walker's Log, now there's thing of pure beauty. Love it.
    The question I have is - when the 'fish' is nicely polished up as I've seen some to be, is there no chance that a hulking big marlin or other game fish might come by and take a swipe at it, thinking it's live bait? Just wondered about that, would be really sad to lose your 'the fish' from your log, especially if you were half way across the Atlantic. Perhaps you'd care to comment? Thank you!

    I seem to remember on my chart of Alderney there were areas last surveyed in the 1800's still pretty accurate for the visible rocks but you needed your wits about you working close inshore. A tip my dear old Dad gave me was to aim deliberately off to one side of the port you are aiming for when the viz is poor. This came in really handy when trying to find the entrance to Lymington in the fog as one bit of marsh looks the same as the other, at least you knew which way to turn when you spotted it.

      It was the same in aviation before GPS in places like the Amazon, if the airport or landing strip was near the river you would deliberately fly say 10 degrees off, then you knew which way to turn to find the strip. It worked fine.

    Hi Tom, its a bugbear of mine that we do not seem to be able to find the survey data on the electronic charts. For example on Navionics it would be useful to see that little Survey chartlet somewhere. If it's there I can't find it. As you say its an optimist or a gambler who uses it to navigate too precisely, tempting as it might be. Love the videos

    Thanks Tom. I bet it took you a good while to figure out how to tell this so clearly: so easy to come over as a befuddled story. But you cracked it. Well done; clear and not a wasted word. BTW for some reason it brings to mind Heisenberg’s Uncertainly Principle. In case you don’t recall it... it says that the more exactly you try to measure something, the more the act of measuring it interferes with the thing you measuring and so changing it. All about sub-atomic physics, but the idea’s interesting and had parallels. For example, if a copper’s trying to measure the speed of passing cars, and tries to get a precise measurement by, say, using big kit and a tripod and on a straight bit of road, then the drivers will see him and change their speed. But if the copper settles for a less accurate measurement, then the drivers may not see him and not change their speed. The point of all this is... if you want to know something (e.g. lat/long, how many people attended an event, how many died of C-19) you must first decide how accurate you want the answer to be. High accuracy is expensive and interferes with the answer, so should be saved for where it’s really necessary. Real world example 1: the degradation of GPS accuracy for open use. Real world example 2: how accurate is a car’s speedometer? Clearly they’re not super-accurate as that would be super expensive (and have to cater for the wear of the tyres etc.). But they need to be cheap and accurate enough to (a) avoid the manufacturer being sued for lots of owners getting tickets due to a misleading speedo, and (b) give a decent idea of speed. The answer: everyday car speedos under-read vehicle speed by between 3% and 8%.

      Good question Mark. Yes there was / is. What you do is carefully unhook the line from the log mechanism. You them pay this end out while hauling in the fish end. Once you have the fish in hand, hold it while the hook end trails astern. It untwists quite quickly and you can them coil it neatly away. The trick is not to let it go, of course and the way you do that is to let it out around a stanchion so that if you do drop it you've every chance of grabbing it before it disappears!
