Basic skills in coastal navigation remain essential. Most chartplotters will not keep you out of harm on shoals, obstructions, etc. It's essential that you know how to read a paper chart to get the "big picture" that you can't get with a 5" screen. You can zoom in, zoom out all day long, but it ain't the same thing.
Absolutely - I love getting the copy of 3001 out to start planning the circumnavigation of Vancouver Island. Even on the desktop computer it is not the same.

Thanks chris12345. thank you. ( I do from time to time take a paper chart into my cockpit, but it suffers greatly.)

OMG Jack...keep an eye on that Portland Plotter! I've been following a story out of England where a Portland is suspected in the disappearance of medium sized ketch. The pouch was left at the finger dock...it's their only lead thus far.

Re: Traditional Navigation

And Joe that is why I use a Portland Plotter.

Dangers of Paper Charts

There was a group of 3 boats, each had 2 couples on board. They were heading south, through the ITCZ.

All three boats were loaded with the latest electronic equipment, but only the last boat also kept their position with traditional paper charts and instruments. It was during a very strange, overnight electrical storm, the unthinkable happened. The two lead boats lost communication with the trailing boat. Their expensive electronics failing them, they could not see or contact their friends in the trailing boat. It was a long, terrifying night at sea, lost, separated, unable to watch DVD movies, play Xbox games, even the Kindle was malfunctioning. Their only hope was the last boat, keeping position with traditional paper charts.

The next morning they found the boat, drifting, with torn sails and deck in disarray. As one guy boarded the boat and went below, he was met with a most gruesome and horrifying sight: The man was laying in the cabin floor, surrounded by a pool of blood! There were many, many small puncture wounds in his back, and three bloody pencils sticking out of the body. There was an eraser in his mouth, and a chart had been wrapped around his broken neck.

In the head was the woman, slouched over the head covered in blood. A pair of dividers sticking out of her neck! He heard a sound...click....click...clack...click....and as he looked into the forward v-berth, he saw a parallel ruler, standing on it's end, walking toward him all by itself, maintaining a perfect heading! Click....click.....clack.....click....

He ran from the boat screaming. Leaving it adrift, he told the other cruisers what he had found and the horrible sight he had seen. They reported it to the authorities, but to this day, the boat has never been found. Cruisers in the area report, late at night, hearing a click....click...clack...click of the parallel rulers echoing across the waves.

If you hear this sound and come across a boat adrift: Do Not Board!! You may meet the same gruesome end.

Re: Traditional Navigation

Silly to assume the charts were not inside the boat, on the chart table, and had been taken to the cockpit. That was never mentioned or even inferred. It never even dawned on me someone would do that, take the charts to the cockpit in foul weather.

Thanks for pointing that out though....glad we can learn from your mistakes.

Re: Traditional Navigation

I can't belive we have a class of SAILOR who thinks of a chart as the "old fashion way"! It's the only way! I'm stupified by the post G.P.S. crowd who actually defend the position of "why learn the basics when I have a gadget" Not only that, but they seem to be proud of it!! I live in Key West and consider myself open minded and I certainly don't mean to offend, but we call those dudes "Gadget Fa%$ets"
.................................Someone had to say it.

Re: Traditional Navigation

If you have a gps and a chart of the area you can get a pretty good fix on your position using the lattitude and longtitude. Taking sightings of landmarks such as lights or structures with a hand held compass will also help. Charts also give you depth, channel markers and other info to help you. Have fun.
