To all of you in the peanut gallery who tore down this young man's video over a misread directional heading; Where are your PERFECT presentations??? The CONCEPTS presented here are ROCK SOLID!
He makes a mistake... He already gets the MC as of 301° and does not have to look at his devation table. If that table had a devation of -5° he would have bin of pudding on a steel ship.
Sir Thank you for your effort for posting this kind of educational materials.. It helps a lot.. Specially your Rules of the Road and Aids to Navigation videos thanks Sir God Bless...
8:12 If your dividers can't spread that far, that's a good indication you are going to use an invalid length for a mile. It's better to spread the compass 1 or 2 miles, then walk it along your course until you get to 8 miles, then grab the remaining 0.86. Gives a much more accurate result. Even if there is not much variation in the length of a mile from the top to the bottom of a chart, it's a bad idea to get used to measuring distances from the bottom right corner of a map, since on some maps there could be a substantial difference between miles at the top and miles at the bottom of a chart. This is more apparent on large scale passage maps.
@@mykeythefishamador2213 You mean the variation in length of a mile? That's just a property of the Mercator projection. You can read more about it here: en.m.wikipedia.org/wiki/Mercator_projection#Distortion_of_sizes
I'f you get a magnetic cours it gives you already the deviation inside... You have a magnetic cours of (KK >> Dev >>) MK 301° >>> Var 15°W>>> TK 286° >>drift>> BTK>>current>> GrK...
A deviation table is specific to each vessel. For exam purposes, you will be provided with a deviation table. You then interpolate for deviation based on your heading.
Once You are changing yr course- there is a deviation table/one page only usually shows particular deviation to each of the next15 degree step...check Magn Comp Log of yr ship. Last deviation Table is usually sticked on the 1st page or close to the main gyro panel /anyway on the bridge)

Thank you so much for all your help! Your videos have helped me so much!
helped me get my 100T. thanks!
Excellent Job. Thank you!
Enjoyable. Thanks. Educational.
Captain, this is awesome !!!
Sir Thank you for your effort for posting this kind of educational materials.. It helps a lot.. Specially your Rules of the Road and Aids to Navigation videos thanks Sir God Bless...
Thanks R.J. I have 15 more chart navigation video coming out this week. Then we plan on going into more aids to navigation. Stay tuned.
US Captains Training
Great Stuff! Helps a lot with the studying

Where did you get the variation?

i found the variation in the other video. thank you man. it was given
thank you
Good job captain
Major help. My Instructor Sucks .....
I'f you get a magnetic cours it gives you already the deviation inside... You have a magnetic cours of (KK >> Dev >>) MK 301° >>> Var 15°W>>> TK 286° >>drift>> BTK>>current>> GrK...
Where can I get that deviation chart? I’m still not sure how to find deviation..
A deviation table is specific to each vessel. For exam purposes, you will be provided with a deviation table. You then interpolate for deviation based on your heading.
Once You are changing yr course- there is a deviation table/one page only usually shows particular deviation to each of the next15 degree step...check Magn Comp Log of yr ship. Last deviation Table is usually sticked on the 1st page or close to the main gyro panel /anyway on the
bridge)
You create one with your ship.
Too easy with your deviation. Usually have to interpolate, but good never the less.
So confusing
