Ocean Voyage Preparation – First Principles

Imagine you are about to sail across the Atlantic in a small boat. You cannot stop for supplies halfway. Every item you bring must be enough for the entire journey, and every decision you make before leaving will determine whether you survive or sink. That is the core intuition: Ocean Voyage Preparation is the process of planning, provisioning, and risk-managing a long, self-contained journey where external help is unavailable.

In the real world, this is not a single formula but a mindset. It applies to any situation where you must operate independently for a fixed period with no resupply. The key idea is that the cost of failure increases with distance from shore — a small mistake at the dock is a small problem; the same mistake mid-ocean can be fatal.

The Precise Statement

In formal terms, Ocean Voyage Preparation is the systematic assessment and mitigation of all variables that affect a vessel's ability to complete a planned route safely, given:

• Duration (how many days at sea)
• Distance (nautical miles to cover)
• Crew size (number of people)
• Vessel capacity (fuel, water, food, spares)
• Environmental conditions (weather, currents, ice)
• Contingencies (engine failure, injury, storm)

The preparation is complete when every critical resource has a safety margin — typically 20–50% extra beyond the calculated minimum — and every plausible emergency has a documented response.

The Three Pillars

1. Provisioning – Calculate consumption rates for fuel, fresh water, food, and medical supplies. Water is the most critical: a person needs about 2 litres per day minimum. For a 30-day voyage with 4 crew, that is $4 \times 30 \times 2 = 240$ litres — plus 50% reserve = 360 litres.

2. Vessel Integrity – Check hull, rigging, engine, electrical systems, and safety gear. Every through-hull fitting must have a plug. Every fire extinguisher must be in date. The life raft must be serviced.

3. Passage Planning – Plot the route accounting for prevailing winds, currents, shipping lanes, and safe harbours for diversion. File a float plan with someone on shore: your departure, route, and expected arrival.
