The manual offers practical pilotage for coastal navigation from the coasts of Brittany and Normandy through the English Channel to Flanders and beyond, compiling tidal schedules, lunar-quarter timings, and the directions of flood and ebb. It lists compass bearings and courses between headlands, depths and sounding recommendations in brasses, locations of sandbanks and rocks, and safe anchorages and berths. Organized by coastal sector and landmark, it gives step-by-step routing and tide-aware maneuvers so mariners can approach harbors, avoid shoals, and find shelter.
