Busola de direcție ar trebui să fie cel mai precis instrument tradițional de la bord, dar poate fi afectată de influențele magnetice din interiorul ambarcațiunii. Schimbarea busolei pentru a determina care sunt acestea și, astfel, pentru a le compensa, este o parte vitală a navigației responsabile, care este adesea trecută cu vederea în lumea electronică de astăzi. Folosind metode practice de-a lungul timpului, nu este mare lucru. De fapt, este ceva ce poate face orice marinar. Tot ce ai nevoie este un prieten bun, o zi liniștită, o busolă purtătoare de mână și aproximativ o oră de rezervă. Iată cum! #navigație. #yachting. #busolă. #TomCunliffe Dacă sunteți interesat de navigație, lucruri maritime și drumul sărat către libertate, vă veți bucura de canalul meu, așa că turnați-vă un pahar din cele mai bune și relaxați-vă cu amestecul meu personal de fire și material didactic util.

  4. My compass on a steel boat is max 5 degrees out. In practical terms, that is more or less within the accuracy I am able to steer. There are some plus and minus as we sail along. But in sum, on an 8 hour sail, I am more or less spot on. I have been sailing for 60 years. So GPS is a relative new thing to me, first GPS on the boat we have now, less than 15 years ago. I have never had a log, just clock, paper and compass. Of course, today GPS. The point being, I know the copass is out 🙂

  8. Excellent Tom Cunliffe!
    I also swing my compass from time to time. Your method is easier than mine. Deviation cards are important and builds confidence to trust our compass readings.
    In the 1980s, I had NO Loran or GPS and NO sextant. But I only did coastal sailing and used Deduced Reckoning (DR) with hand bearing compass fixes for LOP plotting. It was fun.

  12. I guess my question is why is the HB compass used as the standard? Why can't it be wrong – effected by the same on board magnetic effects as the binnacle? EDIT: OK – I see this has been asked and answered. So if you swing the HB through 360 degress and the "cow" is still at the identical bearing, you're good. I guess.

  14. Two of your books just arrived in the mail. This sort of tip is why I bought them. Good old fashioned, hard earned knowledge. Thanks for sharing it with us!

    Does AngelNav have a deviation card built-in? Maybe best to have it on paper anyway, but it could help a bit with subtraction/addition (I know, I'm lazy).

  16. Thanks for this. I learn a lot from your videos. Do you notice any difference in steering compass reading if your engine (and therefore your alternator) is stopped, or if the electrical system is on or off? Yours is on a binnacle, and I didn’t notice whether any electronic gear is mounted nearby. I was also thinking about bulkhead mounted compasses that might have a VHF radio mounted a foot or two away.

  20. Your method is OK if you have a crew member to run the hand bearing compass, and if it can truly be guaranteed that somewhere on your boat will be free of deviation, and that the hand bearing compass does not suffer from lag due to internal friction.
    As a solo sailor I use a combination of known transits (as published or plotted from paper charts) and GPS to satisfy myself that the main steering compass is within 2 or 3 degrees – which is close enough, given the unknown effects of drift etc.
    In the narrower reaches of the river where I sometimes sail I have seen external magnetic influences such as ships, tank installations and overhead power lines cause compass errors, and of course the effects of electrical equipment must be considered. If you sail at night there’s no point in swinging the compass by day with internal compass lighting off, but on the other hand if it’s swung with lighting on, the deviation card is only valid for that condition.

  21. Stunning! I never thought about it but to my excuse I am not a boater.
    Is there no way to calibrate the compass to compensate for the misseeading?
    Or is the deviation so inhomogeneous that you cant do a compensation and need the table for every quadrant as it is a diffrent reading?
    Thanks for the education, great job to get my brain working on this 😊.
