Old Charts

I have a pile of charts from the 60s, and am planning a trip from Lake Ontario to the Maritimes. Would these charts be useable, or should they be tossed or kept as a collector item. We will also be installing some type of chart plotter system, so the paper charts would serve as a back-up. I know charts are constantly updated but I do not know how much they change or at what point they can't be trusted. Any thoughts, recommendations. Thanks!

Re: Old Charts

The rocks hardly ever move.However the bouys do.Also,there are "traffic lanes" & calling in proceedures near major ports & shipping lanes.
At very least-keep ur old charts & buy a 7-10" plotter-something u can see detail on without a magnifying glass.For Eastern Canada,C-map charts have the best detail re navigation.Navionics & Garmin,etc are not as good north of Maine.A smartphone with $50 Navionics downloaded would make a back-up.
For safety,u need a decent radar-17"dome,at least.WE make fog here thick enuff to drink < 150Ft vis.is not uncommon.We consider a mile to be good visibility.Nice/bad thing about really thick fog is no wind.Run the radar,even on clear days-it's the quickest way to become confident with it,as you can visually see ur surroundings & compare to radar display.

Atlantic Coast Sailing Directions


Buy the required "Sailing Directions" booklets from CH Service for your trip.

Also Tidal Current tables are available from CHS or online. Knowledge of currents can speed or impede you greatly. 2-4 kts in many places. Use currents to your advantage.

Re: Old Charts

I'd probably use them for a DR plot and as backup, but wouldn't rely on them for any man-made features. Maybe use them for wallpaper, or donate them to a sailing club for their nav classes?

Re: Old Charts

Get a Davis type radar reflector & mount it 1/2 way up your backstay.
Make sure it is at least 6ft above or below your radar scanner,to avoid false echos,shadows,etc.
Where do you plan to travel in Maritimes? /Cheers/Len

Re: Old Charts

If nothing else--- the old charts will make a unique wrapping paper for the Christmas gift you got me.

That's the answer I'm going with. Those charts are half a century old.

Re: Old Charts

IMO your old charts can be very useful as backups to a primary chart system (as you said, a chartplotter unit). Just keep in mind that many manmade features and aids to navigation will be plain wrong on the old charts. Maybe update with paper copies of important harbor charts. If option being considered is just chucking the old charts and relying purely on the chartplotter, I would say much better keeping the old charts. Can study your route and compare charts to chartplotter info and mark notes on the paper charts. Situational awareness required for use!

That's what we use them for. Peeps who have never been to sea think they're pretty cool.

Re: Old Charts

Sometimes seafood restaurants frame old charts and hang them on the wall. You might be able to sell them for a few dollars.

Re: Old Charts

Thanks for all the thoughts. As I suspected, seems best to keep them as a back up and for fun to be able to do navigation work and course plotting with the kids. Thanks for the other suggestions also. We do plan to add Radar, though thats a tough one to absorb the cost. Will also get the sailing directions booklets. Thanks again!
