        "note": "The current is found by comparing where dead reckoning said you'd be with where a fix actually puts you: the set is the bearing from the DR position to the fix (the way the current pushed you) and the drift is that distance ÷ the elapsed time. So a fix 3 nm at 045° from a 2-hour DR means a current setting 045° at 1.5 knots — carry it forward to correct the next leg.",
