I like the old school navigation of dead reckoning even if it’s not very accurate. With a compass built into our binoculars, its easy and accurate to get a bearing. As we were going down Lake Erie I was wondering where the Weland canal came in (the canal around Niagara Falls), I was hoping to see some commercial traffic. I could see it on the electronic charts but I couldn’t see it on land and then it hit me, this is a big loss with electronic charts, not being able to get a bearing to a target. I’m sure there is a way, but I haven’t figured it out yet. Likewise, I wouldn’t know how to put a bearing in to validate our current position. Instead, I use the phone or the iPad to validate the chartplotter and we already know how well those devices have worked in Canada -NOT. As long as GPS doesn’t go out I’ll be fine, but if I need to dead reckon, give me those paper charts!
To all those who insist on paper charts as a backup to electronics, “what good are they in fog?” What was a surprise to us was the frequency of fog on the lakes, it wasn’t anticipated by us, seemed like a New England issue not a lake issue. But the water is cold (60s in the big water) and the air is warm which is perfect for dense fog. We learned at the shipwreck museum that a large percentage of ship wrecks on the Great Lakes are ships driving into other ships, mostly in dense fog. Radar, GPS, electronics charts and AIS should mostly preclude this cause of shipwrecks. We expected the number one cause for shipwrecks to be bad weather (think Edmond Fitgerald) but bad weather only accounted for ¼ of so of great lakes shipwrecks. With far better forecasting today, this too shouldn’t be an issue like it used to be. But back to our story, without radar, we played our fog horn, set a watch on the bow, watched the AIS for ships (we could see them ...
