Intercept method principles, assumed position, azimuth, plotting a position line, and transferred lines.

Noon sights, meridian passage, declination, observed altitude, and latitude by sun.

Using sun, moon, star, or planet bearings to check compass error.

Route choice, watch systems, crew management, stores, water, spares, communications, and emergency planning.

Global circulation, trade winds, ITCZ, pressure systems, routing weather, and ocean forecasts.

Formation areas, seasons, dangerous semicircle concepts, avoidance, and practical routing caution.

Navigation without electronics, log records, dead reckoning, astro fallback, and equipment failure planning.
