LOL I had to build a rough sundial never know when sun is exact overhead. That's good teaching my navigator friend taught me to draw it each time too.... Thanks for another great video!

Hey thanks! I actually learned how to get bearing from a Croatian Navy navigator a few years ago, he was so nice and our families bonded over the internet. He died right before covid unexpectedly, have been sad about it for a long time. So videos like this mean alot to me on another level. I built my own device to get angle since I could not afford a good sextant and was able to go thru the calculations for good practice. This video took the mystery out of how the device works, super appreciate it!

But the Earth is flat. What part of a flat horizon do you not understand? Even a basketball is rounded in 360 degrees, no matter where you were on the basketball.
@robertlafleur517927 күн бұрын
Earth is flat? Really? Why is it then that none of the flat earthers I gave a Celestial Navigation problem were able to solve it using flat earth geometry? I only get excuses, insults or they run away.
@marcg168616 күн бұрын
We do understand why the horizon is flat. The horizon is a circle of equal altitude.

My Davis "plastic" Sextant was out performed by a HOME MADE Sextant put to gather from bits and pieces left in the junk box at the engineer department at school. Was highly accurate, even when tested at sea on a 48 foot sailboat traveling from San Diego to Hawaii ! So, no. I'm not going to spend any more cash on these plastic toys. Give me metal every time.

I was a USAF RC-135 navigator back in the 80-90s. We used to shoot cell every 20 mintes for up to 12 hours on a flight going 450 kts. Works pretty well in a stable platform if you do your calculations and plotting correctly. Thanks for sharing.

Third video I've watched on the sextant so far and the best. I like how it gets to the basic idea of what you do and what you see etc. I knew nothing about it 10 minutes ago now I got a rough idea. I wanted to research after seeing Robert Redford use one in All is Lost. Next thing I wanna look up is, how do you take those measurements and apply them to a map? I guess there is a video on that also. I will look.

A simple question, Do you need to factor in Equation of Time to figure things like Time of Phenomenon - sunset and so forth ? OR are the daily page times already adjusted for us ? Thanks in advance for advice on this.
@marcg16865 ай бұрын
Chris has three videos dealing with basic, intermediate and advanced concepts of time. Very informative.
@causewaykayak5 ай бұрын
@@marcg1686 Thanks. I've been over these a few times but Equation of Time doesn't get a mention except to say it is included in the Daily pages box, page bottom alongside Sun and Moon transit times. What I have "worked out" for myself is this: taking an example from today's entry - Meridian Passage given as 1205 UT and EoT for Noon as negative 04':54". It seems plain that 6 seconds have been rounded off. For tomorrow (March 29th. 2024) the rounding is 24". This practice is evident in the Nautical Almanac for all recent years. I was a bit thrown when there is otherwise insistence on time keeping precise to the second. In the NA Auxiliary & Planning Data para.18 (page 260 in UKHO volume for '24) advice is given to adjust mean time by applying EoT. No mention that the time of Meridian Passage is perhaps already adjusted. It is I think a Grey area. I make solar compasses of the Bagnold type and prepare setting tables for these. It's a historic feature of these that individual operators make their own adjustment calculations for LAN at their DR position. The values for this (EoT) are taken from the Analemma. PS Are you The Captain Marc attending the past Sailings online classes ? If so Greetings. Many Thanks for the input 👍🏼

How does the second matter when it takes several seconds from when you are done with the reading and have written it down after looking at your watch?
@karhukivi4 ай бұрын
You look at your watch first. The reading stays on the sextant if you don't move the arm.
