Provisioning for an Ocean Passage: Feeding a Crew Offshore

There's a reason experienced cruisers say the quality of a passage is determined by the quality of the food. On a multi-week ocean crossing, meals are the punctuation marks in an otherwise undifferentiated stretch of sky and water. They're the thing the off-watch looks forward to, the ritual that anchors the day, and — when done well — a genuine source of morale that compounds over the length of the passage.

Bad provisioning, on the other hand, erodes everything. By day five of canned soup and stale bread, the crew is lethargic, irritable, and dreaming about port. By day ten, they're questioning their life choices. This is not hyperbole.

Here's how to feed a crew offshore.

Planning: Work Backwards From the Passage

Start with the basics: how many people, how many days, three meals per day plus snacks. Add 30-50% to your estimated passage time for margin — if the routing says 14 days, provision for 20. Calms, storms, gear failures, and diversions all add time. Running out of food is a much bigger problem than arriving with extras.

For each day, plan specific meals. Not "we'll figure out dinner" — actual meals with actual ingredients. This serves two purposes: it generates a precise shopping list, and it creates a menu that the crew can look forward to. Post the menu in the galley. On day eight, when someone reads "lamb curry with rice and naan" on tomorrow's menu, that's a morale event.

Caloric needs offshore are higher than you'd expect. Even in warm weather, the body burns more energy at sea — constant low-level physical effort to brace against the boat's motion, interrupted sleep, and the metabolic demands of thermoregulation all add up. Budget 2,500-3,500 calories per person per day, depending on conditions and crew size.

The Fresh Window

Fresh produce lasts longer than most people think, if you select and store it correctly. The key is understanding which items are hardy travelers and which aren't.
