"CAUTION: The information shown on this chart is of a reconnaissance nature and mariners should exercise caution when navigating in these waters."
My all time favourite was the chart for the very northern tip of Labrador in the McLelan Strait area. We had been bashing our way north for 12 long hours, hoping to get to Port Burwell that day, but we were getting hammered by a gale and by the katabatic winds howling down the Fjords. I'd had about enough of getting beat up so we started looking for someplace to hide. We could not find anything suitable and so decided to anchor in a place called Clark Harbour -- immediately south of McLelan Strait, but which had big red letters: CANCELLED written across it. Still, we headed in to the area and found a decent anchorage and some protection from the storm. As my father used to say: "better than a kick in the arse with a frozen boot".
In many areas, because of the lack of detailed information on the charts, we were travelling more or less blind and relying heavily upon our radar, sounder and DR plots and tracks on the chart. GPS was useful but in that area, depths were our major concern.
Interestingly, the chart we had for the Fogo Island area appeared to be quite dated. I am certain the information was over 100 years old. Nevertheless, it held us in good stead.
As for metric charts, I have a serious and passionate dislike of these and an equal dislike for those luminaries in Ottawa who decided to replace fathoms and feet with meters. I have never been able to wrap my head around the use of meters for measuring depths. In fact I was on a small vessel that ran aground because the skipper got confused over feet vs. meters. Most of the charts for my particular area are still in fathoms and feet -- (mostly because Ottawa is too damn tight-fisted to update our charts), as is my US-made sounder, so I intend to hang on to these. Metric tyrants be damned.
