We entered Astoria in an unexpected/unplanned stopover some years back. The crossing was uneventful entering and leaving; we were fortunate to have benign conditions, but we missed the markers for the channel that hangs a sharp right and follows the back of the spit.. consequently suddenly noticed very shallow water on the rhumb line to the Astoria bridge. We turned quickly and found the channel... a few days later observed a fishboat high and dry on the same flats.
In hindsight this was a foolish move, our skipper had not planned to stop here and did not have the necessary charts.. however at the time we had little choice. Live and learn...
