Ep 37: Navigation: Basic Plotting Part 1 

Very clear description of how to proceed. I just touched on Navigation in my ASA103 course which I completed today. Very much appreciating your enthusiasm for sailing.

Amazing video and very well discribed. I never touched a boat until 6 months ago and today i got assessed and signed off on crew for marine rescue in Australia. 12 meter stabber twin inboard 840hp. Rated to 200nm. The instructor asked about my hours because i could operate and navigate / dock it fine and that i should go for my master cert. The only peice im missing is charting and hours on board. I only have 90 of the 150 for up to 3nm and 300 for over 3nm. Sorry for the rant. But you helped me so much and im genuinely excited.

Absolutely brilliant. Great refresher. I agree I loved teaching this subject when I was in the navy. Every time you managed find yourself exactly on the same position as your fix, there was always a personal sense of achievement. Sounds silly but true. I cannot recommend this great tutorial enough. It is so easy to get used to electronic navigation and finding yourself uncomfortable when having to resort to manually plotting your fix and course. Thank you once again for this great tutorial.

Your videos are superb. Thank you for the great work and for sharing this with everyone!

DR - simply a hash on a line or x. Marked as "DR". GPS "fix" - lat and long "cross" with a circle around it. No "GPS" (unless you want to). Radar - bearing from land with a hash at distance. "Radar" not necessary as its clearly a bearing and range (or more correctly, 3 ranges). 35 years of commercial "sailing" with a dozen nationalities, world wide, all done the same. Rather than use the CR - just use the long lines with the bottom to the Parallel Ruler. LOP has arrows at both ends. "Advanced/Transferred" LOP has double arrows at each end. The correct position in your cocked hat - is the position that puts you in the most danger, not the centre. PS you're videos are extremely well done.

Thank you so much for this overview of plotting. I've got a basic idea now. But much more to learn.

Amazing explanation. Thank you so much!

I am new to this. We are from South Africa and nearly finished building a Wharram Tiki 38 so i need to get ahead of navigation. Great Explanation. Thanks Chris

Thank you! That was a great review for me!

Thank you so much for this. Your videos are very concise and informative. I've always loved looking at maps and globes since I was a child. Little did I know that I would be armchair-sailing (hopefully will transition soon to actual sailing). There's something very satisfying about being able to locate oneself using a compass, map and a timepiece! I hope the Part 2 video will be coming along soon. Thanks and god bless you sir

I'm seeman i mean I'm maritime operator in MOC Puntland somalia (Maritime operation centre), your video is helpful 👌 👍

Thank you very much! This is very clear and we'll explained.

Very informative!

Many thanks for the information shared with us

Just completed my Basic and obtained my PCOC next is this stuff. It truly scares me but at the same time a sailor with no baring is not much of a sailor. You short video has taken some of the daunting edge off what awaits me. All I can say after watching Jessica Watson's netflix special dyslexia means a will to survive a world of wolves everyday of your life and come up shining. Thanks again for your dedication to your craft.

Love ur video ...great job thanks

Yeah boi!! Getting back to business!!

Very clear lecture thank you from Stuart from England

Fantastic presentation

Thanks for the great videos Marco! I've been sailing dinghies and cats out of Jericho, and slowly getting into keelboats. Your many videos have been awesome to help me learn all the different skills for keelboats. A massive bonus that we sail the same waters, see you out there!

Excellent, thank you ..

So easy to understand

Great video: clear, direct and simple. If I use parallel roller s than they should be brass as that will be heavier than plastic and less likely to move as you “walk them on”. Where did you get your protractor? You may have referenced that somewhere but I missed it. Thanks

Anxiously waiting for part 2.

Love your videos (and your calmness). Would have loved to join your school if I was in BC. I am currently talking the asa courses here in SF, and feel that the instructors are not thorough, brash, and expected you to know everything. Thanks for these videos as they have helped me tremendously.

Great video…

thank you

1. Dead Reckoning 2. Running 3.Radar 4. GPS Learning DR for when the lights go out.

Great episode! Thank you. When will you publish Part 2?

I’m going for a big license so every help is welcome. Thank you.

Fun!

good material, maybe as next part guidance including wind and currents too...

Not much to add to that. If I'm on a dead reckoning course (with nothing to bear towards) and especially in a sailboat, I'd assign a safety bearing to the flashing mile marker on your port side, which must not be exceeded else we are too far to port. I'm a line mark only guy for plotting, to reduce confusion, as is the Royal Norwegian Navy. Bearings to LOPs I always mark with a small greek letter "phi". The course line I only mark with course and leg distance, unless it is bearing towards something in which case I add an arrow.

is it weird to verify ones location with the GPS instead of trusting physical measurements? is it more likely that the GPS is right or that ones measurements taken in real time are more accurate?? can you get both answers to agree and still be in a different place??? new to subject just curios what should be trusted more.

Question please: You explained that you plotted your LOPs after converting them from magnetic to true but, if I remember correctly, you them labeled them as magnetic. What am I missing? Tx.

Hey, Marco. I hope you are well.

🌎👍❤

Are magnetic bearings cyclical? Would old charts reflect magnetic bearings in time?

Can I download your entire series and save for reference ?

Protractor, rule, pencil….. people still actually do this with all the gps and satellite tech? Wow reminds me of flying in the Vor and loran days which nobody does now.

I have also heard of "navigational triangles", which can replace both parallel rulers and protractors. 7:32 - That's actually a custom-printed chart. There are no charts in the CHS catalogue with that scale and those limits.

2B or not 2B?

No tidal stream input?

Do you offer "on the water" courses? Our VdS 34 is at Mosquito creek and I would like a few days on the water for you to cruise with us or just with my partner so she can learn all this. Also, what is that notebook you are using and where to get one? And is that a staedler pen what model? Thank you!

I would not trust these products... The only thing that was good from them for me was there mini blender and solar lantern... everything else I purchased sucked...

Just point the boat south and show us the icewall
