How to Provision a Sailboat for a Voyage

Provisioning — buying, organizing, and storing food and supplies for a sailing trip — is one of those skills that separates comfortable cruisers from miserable ones. Get it right and you eat well, waste nothing, and never run out of coffee 700 nm from the nearest supermarket. Get it wrong and you're eating canned beans for the third night in a row while someone discovers the fresh tomatoes rotted in a locker nobody checked.

The approach differs dramatically by trip length. A weekend coastal sail needs a cooler and a shopping list. A two-week island hop needs careful planning and local market knowledge. An ocean crossing needs a military-grade provisioning system. This guide covers all three.

The Three Provisioning Tiers

Tier 1: Weekend to One Week (Coastal Sailing)

This is simple shopping list territory. You have access to stores at most stops, refrigeration works because you're running the engine regularly, and fresh food stays fresh.

Shopping list for 4 people, 5 days:

Budget: $200–$400 total for a week of generous eating. Add $50–$100 for alcohol.

Pro tip: pre-cook one or two meals at home and bring them in sealed containers. Day one on a boat is often chaotic — having a ready-to-heat dinner saves the evening.

Tier 2: One to Three Weeks (Island Hopping / Charter)

Now you need to think about food spoilage timelines and storage strategy. Fresh produce has a limited shelf life without shore power running the fridge 24/7.

Fresh food spoilage timeline:

The golden rule: eat the most perishable food first (salads, berries, soft cheese in days 1–3), then transition to hardier items (cabbage, carrots, hard cheese in days 4–10), then fall back on canned and dried goods for the remainder.

If you're chartering in the Mediterranean or Caribbean, local markets at each island stop let you refresh supplies every 2–3 days. For a detailed look at provisioning stops by region, see our Caribbean sailing destinations or Greek islands sailing guide.

Tier 3: Ocean Crossing (14–30+ Days)

This is where provisioning becomes serious logistics. You're leaving a port with everything you'll need for 2–4 weeks, there are no resupply options mid-ocean, and calorie requirements increase (3,000–4,000 calories/person/day when sailing offshore — the cold, the physical work, and the sleep deprivation all burn energy).

Master provisioning list for 2 people, 21-day Atlantic crossing:

Budget: $400–$800 for two people, 21 days. Less in the Canaries, more in Scandinavia.

Use Breezada's sea distance calculator to estimate your crossing time — a 2,700 nm Atlantic passage at 130 nm/day is roughly 21 days. Always provision for 25% more days than your estimated passage time.

Storage and Organization

The Locker Map

Every provisioned item needs a known location. Create a locker map — a simple diagram showing which locker holds what. Tape it inside a cabinet door. When someone asks "where's the rice?" at 3am in a rolling sea, you don't want to open every locker searching.

Canned Goods Preparation

1. Remove all labels — they'll disintegrate in bilge moisture and clog pumps
2. Write contents on the can with a permanent marker (top and side)
3. Remove cardboard packaging — it holds moisture and breeds cockroaches
4. Store heavy cans low — ideally in the bilge or lowest lockers for stability

Refrigeration Strategy

Boat fridges are small and energy-hungry. Prioritize fridge space for:

• Meat and dairy (must be cold)
• Opened sauces and condiments
• That night's dinner prep

Don't waste fridge space on: beer (use a cooler or the ocean for chilling), uncut vegetables (they're fine at ambient temperature), or canned goods.

Meal Planning

Write out a meal plan for the entire trip before shopping. Not because you'll follow it exactly, but because it forces you to calculate quantities accurately and ensures variety.

A good offshore meal rotation:

• Day 1: Fresh steak/fish, salad, bread (celebration meal)
• Days 2–5: Fresh meals with decreasing perishables (stir-fry, pasta with fresh sauce, wraps)
• Days 6–10: Canned protein + fresh vegetables (tuna pasta, chicken curry with rice)
• Days 11–15: Canned everything + dried staples (bean chili, corned beef hash, lentil dal)
• Days 16+: Emergency rations mode (pasta with jarred sauce, rice with soy sauce, canned fruit)

Water Management

Water is the most critical provision. 3 liters per person per day is the minimum — more in hot climates. For a crew of 4 on a 21-day passage, that's 250+ liters of drinking water alone, plus cooking water.

Options:

• Tank water: most cruising boats carry 200–400 liters in built-in tanks
• Jerry cans: 20-liter jugs strapped on deck, easy to fill and manage
• Watermaker: a reverse-osmosis desalinator producing 40–80 liters/hour. Costs $3,000–$8,000 installed. Essential for long-term cruising, optional for a single crossing

Never rely solely on a watermaker for an ocean crossing — they break. Carry enough stored water to complete the passage without it.

Provisioning in Different Regions

Caribbean

Stock up at the major islands (St. Martin, Antigua, Barbados, Trinidad, Grenada) where there are proper supermarkets. Small island mini-marts have basics but at 30–50% markup. Local fruit markets are excellent and cheap — mangoes, papayas, bananas, and limes are abundant and affordable. For routes that pass through remote areas — like the Panama to Colombia passage via the San Blas Islands — provision fully before departure, as there are no shops in the archipelago beyond occasional lobster and coconuts sold from canoes.

Mediterranean

Provisioning paradise. Every Greek island has a mini-market, every Italian port has a deli, and every Turkish town has a fresh market. Stock your staples at the charter base (major city supermarket) and refresh fresh items at each stop. Greek markets: amazing tomatoes, feta, bread. Italian: cured meats, pasta, wine. Turkish: the cheapest and freshest produce in the Med.

For any sailing destination, use Breezada's distance calculator to plan which ports have provisioning and how far apart they are — running out of fresh food 40 nm from the nearest market is preventable with route planning.

Common Provisioning Mistakes

1. Buying too much fresh food — it rots before you eat it. Buy less fresh, more canned/dried
2. Forgetting condiments — salt, pepper, oil, garlic, and hot sauce transform boring canned meals into edible ones
3. No snacks — offshore watches are boring. Snacks are morale. Buy twice what you think you need
4. Ignoring dietary needs — seasickness medications, fiber supplements, and familiar comfort foods matter more offshore than on land
5. Not pre-cooking — spend the day before departure making 2–3 freezer meals. Day 1 and 2 are often too chaotic (and too seasick) for cooking
6. Water complacency — always carry 25% more water than your calculation says you need

Frequently Asked Questions

How much does provisioning cost per person per week?

$50–$100/person/week for basic but adequate meals on a coastal cruise. $75–$150/person/week for comfortable eating with wine/beer. $100–$200/person/week if you eat out regularly at island restaurants. An ocean crossing costs roughly $30–$50/person/week since it's all boat-cooked from bulk provisions.

Should I provision before or after arriving at the charter base?

Before departure, at the charter base city. Most charter bases are near major towns with supermarkets (Split, Athens, Tortola, Fort Lauderdale). Island provisioning is more expensive and less varied. Some charter companies offer pre-stocked provisioning packages — convenient but typically 30–50% more expensive than self-shopping.

How do I keep food fresh without refrigeration?

Eggs: buy unwashed farm eggs — they last 2–3 weeks unrefrigerated. Store in cardboard egg cartons, turn them every few days. Cheese: hard cheeses (Parmesan, aged cheddar) wrapped in wax paper last weeks. Butter: salted butter lasts 1–2 weeks out of the fridge in temperate climates. Bread: bake your own — flour, yeast, and water last indefinitely.

What's the one provisioning item people always forget?

Spices and sauces. You can make canned chicken, rice, and canned tomatoes into a dozen different meals with the right spices — curry powder, cumin, paprika, oregano, soy sauce, hot sauce, coconut milk. Without them, every meal tastes the same by day five.
