What do these red line thingies mean?

[TwoFish]

Oh an if the OP (or anyone else, especially if new(ish) to charts) is considering a hard copy of Admiralty Chart 5011, perhaps also consider the book Understanding a Nautical Chart by Paul Boissier (Vice Admiral and former RNLI Chief Exec). That book contains the content of NP5011 but augments it with some very well written pages of explanation as to how it all works.

True north is the direction to the north pole.
Magnetic north is the direction a compass points (the location of the magnetic north pole varies, as does the orientation of the magnetic field in many areas)
Grid north is the orientation of the vertical lines on a map or chart. It's not practical to have all of these align perfectly to true north because of the compromises necessary to represent a curved area on a flat sheet.

Magnetic and grid are approximations, hence "true".

I wasn't asking you!!!

Do a Google search for "International chart symbols and abbreviations". You should find a free downloadable pdf.

Though of course other jurisdictions' equivalents are also available.

There's no such thing as a stupid question but there are a lot of b.... stupid answers.

20 years as a professional instructor and I can tell you this old quote is nonsense. I've heard more stupid questions than I care to remember. I usually let the other students answer the really dumb ones to give some perspective to the person who asked it. Much easier to let their peers tell them how dumb the question was than me do it.

Harsh... The thing is it's not a stupid question in the person asking it eyes. All this macho nonsense, just answer the damn questions.

As a professional instructor, you'll know there are different ways of explaining things. Some students don't "get" something the first time and need an alternative explanation. There are dumb instructors out there as well!

There’s certainly a few inept instructors out there. As them for an explanation and they say the same thing again only louder.

So that guarantees you’ve got a student who is reluctant to ever ask a question again for fear of looking stupid in the eyes of their peers. They go on to at worst fail or at best not do as well as they should have. Great instructing.

When someone needs to ask here about the meaning of symbols on a chart there is a major problem.

Specifically what is the danger in asking questions on a forum? If people aren't allowed to ask, they can't learn, and if they can't learn they will be in danger when they go sailing.

When people belittle others for seeking knowledge, that's when we have a real problem. Hopefully the forum admins will remove your small minded post.

 

[lustyd]

Speaking as one who used to make charts for a living, I thought that was actually not an unreasonable question!

Surely everyone knows it's straight up?

Not if I can help it: I might end up in Yorkshire.

Some people seem slow to realise that the OP is not a sailor. He is simply someone who is hoping to sail in a year or so. I have known some quite decent people who don't sail and wouldn't rate them on average as being more or less stupid than those of us who sail. However, they are almost invariably ignorant of much that we take for granted and I suspect that I would find myself in the same position in the company of bell-ringers or grouse-shooters.

I still remember my confusion when we started cruising about such simple matters as how to anchor. Boat handling was no problem, but I couldn't work out how the anchor made its way from the foredeck to the bottom of the sea or river. All the books gave minute details of the tackle to be used and the scope to put out but it was only Des Sleightholme's book 'Sailing' that told you how to actually do it.

Neeves, I think you asked somewhere up there ^^^ about what sort of charts these are because they don’t look like the ones you are used to. I can’t find the post now and inconveniently couldn’t reply immediately as I had to do some pesky paid work.

The OP is clearly using a mobile app and these are screenshots. I am not 100% sure but it looked a lot like Savvy Navvy. I only used it for a one week free trial. Some of it was really impressive but some things were odd and I couldn’t find if there were settings I could adjust somewhere. It’s undoubtedly a fairly popular app though and depending which mode it’s in probably doesn’t show the traffic arrows to avoid screen clutter, eg it looked like it was actually showing tidal steam arrows which might be confusing to have overlaid with traffic ones.

No. They pay the same attention as everyone else. My favourite dumb questions are the ones where we have had a discussion about a concept or feature, clarified the broad and detailed points, had questions and answers and 10 minutes later the one (and it is usually just the one specific type of character) asks a basic question which was specifically addressed. Normally to the chorus of moans from their peers who appreciate the time constraints that professional training requires.
There is only so far adaptive facilitation can go before one student is compromising everyone else's training.

Feel free to contact EASA, FAA and UKCAA for copies of their audits on my instruction.

Oh forgot to add NASA to the auditors too.

In that case you say either ‘refer to your notes’ or ‘come and see me later’. Belittling someone is never a positive move in a learning situation. Sorry but your attitude is wrong and I don’t believe any audit spotting such behaviour would give you positive feedback. Perhaps the assessors never saw or heard of your behaviour. Anyway since when were the FAA & NASA experts in teaching and learning?

"refer to your notes" is the last thing you should say in an active class or workshop. You've just removed him/her from the group. "Come and see me later" leaves the question unanswered and he/she will be hung on that point for the rest of the lecture. We call that a "blocker". If I repeat the point for the benefit of that individual the others will feel they are being deprived of my time.
Allowing his/her peers to address the point keeps the group involved, demonstrates that the point was covered and understood by the group and informs the individual that they were not focused at the time.

I'm the same instructor regardless of who is attending, auditing or monitoring.

We will agree to differ.
