One final waypoint

On a passage of some length (South Coast to Cherbourg, or East Coast to Flushing, for example), it’s tempting to make the final waypoint at the outer harbour entrance. Once inside after dark, however, shore lighting can make spotting the lights of the inner harbour and the associated buoys difficult, especially for first-timers who haven’t seen the place in daylight. Add a touch of mist or real fog, and you’re lost in no time. The answer is an extra waypoint or two, at the planning stage just in case, suitably screened for potential collisions with other meandering mariners.
