    The instructor's approach simplifies the material and makes it easy to understand. His recommendations prevented me from spending hundreds of dollars on unnecessary equipment that complicated things more. Should we ever cross paths, I'll gladly buy you a drink. Thanks, Northeast Marine Institute, for this video.

    Love this guy. Love when he says “oh no it doesn’t reach!” Every time I’m navigating on charts and it doesn’t reach I hear his voice in my head.

    I have always had a fear of triangles. You cured me in ten minutes flat ! Within five minutes of watching this Iwas using triangles with confidence. I am a keen amateur sailor but have been a teacher (of English) forfifteen years. I can honestly say this is the best piece of teaching I've seen in a very long time.Many thanks Captain Jeff.

    I wish I had watched this yesterday before I bought the "Weems" roller plotter. Back to West Marine to exchange for triangles. Thank you for a great clear explanation.

    very interesting.. I just became involved with plotting courses, and I find triangles better than all other gadgets that I purchased .

    Weems & Plath just gained another sale of two triangles, lol!! Super easy to follow and the accuracy gain really makes using triangles a no-brainer. Thanks for a great video, you got a new subscriber in me!

    Nice lesson! Just FYI for anyone watching this - only 1 triangle is necessary. The demos here used 2 triangles, but the examples could be done with a straight edge (ruler, etc) substituting for the second triangle. This would save the cost of having to have buy a second triangle just to be able to parallelize movements around a chart.

    I still have my Iversen and Weilback parallel ruler from 1963 when I graduated Copenhagen Navigation School. It has served me well over many years. It has, though now worn somewhat, a couple of very thin "cork" pads on the bottom of each half which keeps it from sliding unintentionally.

    Wow. I just picked up a set of navigation tools on ebay, and was mostly interested in the slidebar... But since the set also had triangles I figured I should look up how those are used, and this video has sold me on them.
    Nice work Capt. Jeff!

    Just a tip that is a habit of mine that I'm keen to share.
    For plotting a course or bearings with triangles, place your pencil on the point you're starting on or taking a bearing of and place the triangle touching the pencil. Then run the triangle up keeping the focal point on the meridian so it twists to line up on your course.
    They are great and should be the standard plotting tool on all ships.
    Love the American enthusiasm

    I have always found a roller plotter or parallel ruler to be a nuisance to use because of slippage. Your excellent video convinced me to get a pair of protractor triangles.

    In your example, you could have opened up the parallel ruler to full extension and use the "inside" edges. But triangles are easier.

  • @jeremy9876543
    @jeremy9876543 8 років тому +1

    At the 8:30 mark you use the second triangle to move the first triangle away from the plotted course to get to the meridian. Might it have been more accurate to hold the second triangle on the plotted course and then slide the first triangle until it's converging lines meet on a meridian. This would allow you to visually check that the first triangle is both directly on the plot line and the converging points line up at the meridian. You could only do it this way if your course is at least somewhat off of due North or south.

    Three of my favrite plotting tools are the triangles and the portland course plotter and the vector master, mainly for speed and distance. Reson is simple, they are both vey qwick and easy to use. The only additon i have to make are plotting sheets to help fix a positon on a chart from a gps. so that i do not have to read the side and top scale on the chart.

  • @wesleybuff2536
    @wesleybuff2536 6 років тому +1

    Often times in drafting the edges are beveled with a hollow under the running surface or with dimples to raise the pattern such that ink can not touch the close fit surfaces and wick down the length of your work leaving a massive puddle. I could not tell the direction of the bevel well in the video, but that is one reason for providing a bevel if on the underneath. The knobs may be on the wrong side for that possible answer to fit the situation though.

    The triangles give the course True, what if the question asks for magnetic course? Do you have you use the Compass Ross for that?

    • @chrisbaum5725
      @chrisbaum5725 Рік тому

      Yes, this technique plots True - the protractor is much more accurate than squinting at the compass rose on the chart, as shown in the video. You then just need to do the math (TVMDC) to calculate the compass course.
