How: Wrap in newspaper. Peel outer leaves one at a time — never cut through the head.
Life: 3–4 weeks in cool dark storage.
Avoid: applesbananasethylene producers
How: Do NOT wash before storing — dirt is protective. Needs complete darkness (light causes greening/solanine). Russet, Yukon Gold, Kennebec keep longest.
Avoid: onionsapplesbananasdamp
How: Cool, dark, ventilated storage — same as potatoes.
Avoid: onionsethylene producers
How: Needs air circulation and dry conditions. Do NOT store in plastic bags.
Avoid: potatoesdamp areas
How: Light, dry storage — same as onions. Do not wrap in plastic.
Avoid: moisture
How: Wrap in tinfoil or damp paper towel. Wilted carrots revive in a jar of water.
Life: 2–3 weeks.
Avoid: applespearsethylene producers
How: Cool, dark, dry — like potatoes.
How: Lasts weeks whole and unbruised. A passage favourite.
Avoid: ethylene producers
How: Peel, chunk, submerge in rum or vodka in a sealed jar — lasts months.
Avoid: moisture if unwrapped
How: Room temperature ONLY — refrigeration causes mealy texture and flavour loss. Use green ones first, ripe ones immediately.
Avoid: cucumbersleafy greensfridge
Life: 1–2 weeks unrefrigerated.
Avoid: ethylene producers
Life: Use in first week. Cucumbers highly sensitive to ethylene.
Avoid: tomatoesbananasmelons
How: Not in plastic. Keeper varieties: Braeburn, Fuji, Winesap, Pink Lady. Avoid bruising.
Life: 2–3 weeks.
Avoid: potatoescarrotscitrusleafy greens
How: Keep citrus separate — one mouldy citrus ruins the whole batch. Check daily. Hang in a separate net.
Avoid: other citrus grouped tightlyapples
How: Hang individually if possible. Wrap stems in foil or plastic wrap to slow ethylene release. Buy GREEN.
Tip: Use near hard avocados or green tomatoes to ripen them deliberately.
Avoid: everything — especially cucumbersleafy greensother fruit
How: Buy very green/hard. Ripen using banana proximity deliberately. Once ripe, use immediately.
Avoid: pineapple (flavour contamination)
Mangos: High ethylene — isolate once ripe. Use quickly.
Pears: Ripen on counter; high ethylene producer. Keep from carrots.
Pineapple: Use early. Do not store with avocados (flavour contamination).
Melon: Cool locker whole. Strong ethylene producer once ripe — use quickly once cut.
How: Wrap loosely. Use in first 2–3 days. Romaine lasts longest.
Avoid: bananasapplestomatoesany ethylene producer
How: Very highly ethylene-sensitive — shelf life cut 50% near producers. Use first.
Avoid: all ethylene producers
How: Submerge stems in a jar of water (like flowers). Or chop and pre-freeze in oil in ice cube trays before departure.
Avoid: strong ethylene producers
How: Buy never-refrigerated eggs from a farm or market. Do NOT wash before storing. Turn carton completely upside-down every 2–3 days.
Life: 3–4 weeks. Waterglass coating extends to 9 months.
Storage: Plastic carton only — cardboard disintegrates in humid conditions.
Avoid: direct sunlightcardboard cartons
How: Grow fresh at sea using a mesh-lid jar. No storage needed. Ready in 3–5 days — fresh greens at any stage of a passage.
Ethylene Guide
Ethylene gas from ripe fruit accelerates ripening and decay in sensitive produce. Keep producers and sensitives apart.
- Apples
- Avocados (ripening)
- Bananas ★ highest
- Figs
- Mangos
- Melons
- Pears
- Peaches / Plums
- Tomatoes (moderate)
- Broccoli ★ (-50% life)
- Brussels sprouts
- Cauliflower
- Cucumbers
- Leafy greens
- Fresh herbs
- Carrots (moderate)
- Peppers (moderate)
- Potatoes (sprout)
Strategic use: Put a ripe banana in a bag with hard avocados or green tomatoes to ripen them faster on purpose.
Never Store Together
These combinations actively damage each other — even without direct contact.
Dry Goods & Pantry
Moisture, weevils, and flour moths will find any weakness. Seal everything.
- 1Airtight rigid containers for all dry goods: flour, rice, pasta, oats, lentils, dried fruit, nuts, sugar, cereal. Weevils chew through cardboard and thin plastic in hours.
- 2Freeze dry goods for 3–7 days before boarding, or microwave briefly. Assume purchased goods contain dormant insect eggs — because they do.
- 3Add 2 bay leaves to each container as a weevil deterrent after treatment.
- 4No cardboard ever boards the boat. Remove all packaging at the dock. Corrugated cardboard is a cockroach highway — eggs travel inside the corrugation.
- 5Coffee and tea absorb surrounding smells. Store in dedicated airtight tins away from spices and cleaning products.
- 6Salt shakers: add a few grains of rice to prevent clumping in humidity.
- 7Label stripped cans with a marker on the lid when you remove paper labels.
Provisioning Tips
Rules that experienced offshore sailors follow.
- 1Shop at farmers markets — supermarket produce has been refrigerated and deteriorates faster once taken off refrigeration.
- 2Buy green and unripe for anything you want to last. You can ripen faster; you cannot slow down already-ripe produce.
- 3Do not wash root vegetables before storing. Dirt is a natural protective barrier. Wash right before use.
- 4Inspect everything before boarding. Remove any damaged or overripe pieces immediately — they spread rot to neighbours.
- 5Plan a consumption order. Delicate first (berries, leafy greens, broccoli) → medium (peppers, zucchini, tomatoes) → long-life (cabbage, carrots, squash, potatoes, onions).
- 6Provision 30–40% longer than the expected passage. Weather delays are real.
- 7Wrap banana stems in aluminium foil — most ethylene releases from the stem end. Wrap each banana separately for up to 2 weeks of life.
- 8Bilge is your refrigerator. Use it for root veg, squash, apples, cabbage, and eggs. Waterproof everything stored there.
- 9Hard cheese lasts well wrapped in vinegar-soaked cloth inside an airtight container. Wax-coated varieties last longest.
- 10Sprout beans and seeds at sea. A mesh-lid jar gives fresh greens from day 3 onward — no storage, no refrigeration.
