This guide covers the core calculations required for the Italian "Patente Nautica entro le 12 miglia." Unlike offshore sailing, you do not use declination or astronomical fixes. 1. The Key Formula (True Bearing) Within 12 miles, the Earth is considered flat for navigation purposes. All exercises use True Bearings (no magnetic variation correction required on the chart, though your boat uses magnetic compass).
