The fundamentals that don't change: anchoring, weather, engines, and the night. No jargon for its own sake — just what's actually useful offshore.
Ground tackle, scope, reading an anchorage, setting technique, and why dragging usually isn't the anchor's fault.
Pressure systems, reliable forecast sources, sky signs that hold up, local effects, and when to stay put.
Why diesels fail, bleeding an airlock, the raw water impeller, zincs, exhaust smoke, and the pre-departure check.
Watch systems, dark adaptation, navigation lights, AIS limitations, fatigue management, and arrival planning.
