It’s surprising how often a little chart-reading can save a lot of complicated pilotage. Take this example. Working close-in to the west of Cowes Green, a large heap of bricks with evil intent awaits the unwary. However, if you take a bead along the beach toward the Castle, and stay on it or north of it, you’re in the clear. Natural transits that are not charted as such abound for the creative navigator with the patience to seek them out.
