I'm trying to understand the idea of recommending to know how to do something but not carrying the materials to do so? Is it a case of "because I had to?"I think it’s a good idea
To learn to pilot on paper charts, especially for new sailors.
It’s been about 10 years since I’ve carried paper charts. Their back
Up function has been replaced
With various GPS Devices.

Because knowing the underlying principles is valuable, even if you use the technology. Analogy is knowing how to do long division or basic math, even though you use a calculator or spreadsheet.I'm trying to understand the idea of recommending to know how to do something but not carrying the materials to do so?

Yea....no. I'm not debating the value of learning a secondary or primary technique but I would debate then leaving those tools at home. That would be like leaving your pencil or even worse, your calculator at home (using your analogy, which is a good one).Because knowing the underlying principles is valuable, even if you use the technology.

I think of it like driving. If your driving around the town you’ve lived in for more than a year you can probably get downtown with out a map. But drop that same driver into Seattle traffic and the choice is sit in the I5 traffic or take the side streets and skirt around the back up. If never been there a map would be handy. If you’ve never used a map then your likely stuck.I'm trying to understand the idea of recommending to know how to do something but not carrying the materials to do so?
I can't say for anyone else, but it's been a very, very long time since I've plotted anything on a chart. A picture just appears in my head and that's that. Even on passages we only enter the position in the log at noon each day, and there are no marks on the chart. I know without a doubt that with or without GPS I'm going to be able to get around just fine.I'm trying to understand the idea of recommending to know how to do something but not carrying the materials to do so?

An online subscription is only needed to get updates. This is like hiring someone to keep you paper chart updated with notices to mariners, buoy changes etc. When was the last time you did that?One thing that has been bothering me and would love to get feedback from others much more knowledgeable, is when I've looked into these, it seems they require you to purchase an online subscription to keep the charts updated.
Yes, I've had similar experiences. Sat down with a sailor that knew where I was heading and he marked up my paper chart with a ton of excellent information. I guess you can do something similar with electronic charts, you just need a notebook... But doesn't feel quite as accessible.Last May when we went to Belize, there were no good electronic charts. We had to bring our own paper chart, and it was done by a woman who had charted the passages between the islands. The charter company took our chart and marked it up with their limitations and areas that would cost us a fee or were off limits. THe paper chart kept us from running aground. Which we later learned was a common event in the area. Perhaps the captains arriving for the charter experience had not used paper charts before.
Really interested in the Maritime Provinces. Possibly over to Greenland then to Iceland and the islands beyond. I have been seriously considering a northern route over to Norway. It's all just in the planning stages at this point, and several years off. Although the Martime Provinces may be next summer... Will see...Oh... Where are you heading dLj? Now you got us intrigued. Off the charts?
OpenCPN works worldwide, and it supports Canadian and almost every electronic chart format. You can swap charts online also (but I don’t recommend bootleg charts and those are probably almost as old as your paper ones). Check the OpenCPN forumsOnly works in US waters. Very limited for where I'm heading.
