Provisioning for Passages

Galley Guides · Provisioning

Provisioning a passage boat is a logistics problem dressed up as a cooking question. The goal is to arrive at the end of the passage with the right quantity of the right food in edible condition, distributed across the boat in a way that maintains stability, allows access to what you need when you need it, and does not result in discovering a bag of moulded onions at the bottom of a locker on day nine. Getting this right requires a system — not a rigid plan, but a framework that can be executed in the rush of pre-passage preparation without leaving significant gaps.

The Meal Planning Matrix

The foundation of passage provisioning is a simple multiplication: crew members times days times meals per day equals the number of servings required. A four-person crew on a fourteen-day passage eating three meals a day requires 168 servings. That number, stated plainly, makes the task tractable — you are filling 168 serving slots, not trying to provision "two weeks of food" as an undifferentiated mass.

Build the matrix on paper or in a spreadsheet before you shop. Assign meals to days: day one through three get the fresh food, days four through seven transition to hardier vegetables and preserved proteins, days eight through fourteen are largely from tins and dry goods. Fill in the specific meals — not "pasta night" generically, but the specific one-pot pasta recipe you know cold and can execute tired. Then count the ingredients those specific recipes require, add a 20% buffer for spoilage and unexpected hunger, and build your shopping list from that.

The 20% buffer is not waste insurance — it is seasickness insurance, spoilage insurance, and appetite variation insurance. Offshore calorie requirements are not the same as at anchor. Cold conditions, physical exertion (sail handling, grinding in a seaway, night watches that do not sleep properly), and the metabolic cost of vigilance all increase caloric need. A reasonable estimate is 20–30% more calories per person per day offshore than at anchor in calm weather. In cold or high-latitude passages, that figure can be higher. Plan for it explicitly rather than discovering on day five that everyone is eating through provisions faster than anticipated.

Fresh Produce Timeline

Not all produce is equal in keeping quality, and provisioning a passage means staging the fresh food to match its natural lifespan. A reliable timeline that works for most passage scenarios:

Days one through three are for the fastest-deteriorating fresh food: leafy salads, tomatoes, fresh herbs, cucumbers, bell peppers, fresh bread. Eat the delicate produce first, while it is at its best. A proper salad on day one of a passage is a luxury that pays morale dividends; the same salad on day four would be unappetizing. Fresh herbs — cilantro, parsley, basil — can be kept alive for four to five days by wrapping the stems in a damp cloth and storing upright in a glass with a small amount of water, covered loosely with a plastic bag.

Days four through seven move to the sturdier produce: carrots, beets, turnips, sweet potatoes, cabbage, onions, garlic, citrus, apples, and whole uncut pineapple. Root vegetables and brassicas survive a week at sea without refrigeration in temperate conditions, longer in cool climates. Citrus keeps even better — limes and lemons in a mesh bag hung in the saloon will last ten days to two weeks in most conditions. Garlic and onions, kept dry and well-ventilated, will outlast the passage.

Days eight through the end of the passage, the galley is running on eggs (unwashed, properly stored eggs last three to four weeks without refrigeration), hard aged cheese, and tinned goods. Eggs benefit from being turned every two to three days to keep the yolk centered and prevent it from touching the shell membrane. A simple floating test in a cup of water confirms freshness: an egg that sinks and lies flat is fresh; one that stands on end is acceptable but fading; one that floats should be discarded. Hard cheeses sealed in wax — parmesan, aged gouda, aged cheddar — will last the length of any normal offshore passage without refrigeration.

Icebox Management: Block vs. Cube Ice

Marine iceboxes are not refrigerators. They are insulated boxes that maintain cold only as long as the ice lasts, and the strategy for managing that ice has a direct effect on what you can eat and when. The fundamental rule: block ice lasts four to five days in a well-insulated icebox under normal conditions; cube ice lasts one to two days. If you are buying ice before a passage of any length, buy block. Two blocks of ice in a good icebox will still be providing some cooling at day four; the same volume in cube ice will be water by day two.

The secondary rule: do not use icebox cold for items that do not need it. Beer and wine do not need refrigeration to be safe, and using ice to chill them depletes the cold available for food safety. Dairy, opened tinned goods, fresh fish, and raw meat are the priority. A useful hierarchy: first priority is medicine (any temperature-sensitive medications), second is raw protein (meat and fish that would be unsafe to eat if warmed), third is opened perishables (yogurt, soft cheese, opened tins of tomato or coconut milk). Everything else can adapt.

Minimize icebox opens. Every time the lid comes up, cold air escapes and warm air enters. Develop a habit of deciding what you need before opening, getting everything at once, and keeping the lid down otherwise. A list taped to the icebox lid of what is inside — organized by category — prevents the open-and-stare-while-cold-escapes scenario that novice passage cooks fall into.

Stowage Rotation and the Inventory List

A passage galley stowed without a system becomes an archaeological dig within three days. The crew cannot find what they need, older food gets buried under newer food, and the meal plan fails not because the provisions are inadequate but because no one can locate them. The solution is a rotation system combined with an inventory list.

The rotation system is simple: when stowing, put newer provisions toward the back and older ones toward the front. Last in, first out is the conventional warehouse logic, and the same principle applies in a boat's lockers. When you buy provisions in two or three shopping trips before departure, the last batch purchased should go behind the first. Produce with shorter shelf lives goes in the most accessible locations; tins for the second week of the passage go in the less-accessible deep lockers.

The inventory list is a piece of paper (or laminated card — paper deteriorates in marine conditions) taped or velcroed to the inside of each major food locker door. It lists the contents, their quantities, and ideally the use-by dates of anything time-sensitive. Update it as you use items — cross them off, do not remove the list and rewrite it. An accurate inventory means that the cook at 0200 knows exactly which locker has the last tin of coconut milk without opening four lockers and making noise in the middle of the night.

Waterproof Labelling: Write on the Tin

Tinned goods stored in bilge lockers, under settees, or anywhere near the waterline will, over the course of a passage, get wet. It may be condensation; it may be a wave through an open hatch; it may be a slow drip from the deck fitting above. Whatever the source, the paper labels on commercial tins will soak through and fall off, leaving you with a collection of identical unlabelled silver cylinders that could be anything from sardines to peaches. Opening a tin of sardines when you planned peach cobbler is a minor disappointment; opening tinned dog food (some passages carry it for boat dogs) by mistake is worse.

The solution is low-tech and takes about fifteen minutes in the provisioning process: before stowing, remove the paper labels from every tin going into a locker that might get wet, and write the contents directly on the tin with a permanent waterproof marker. Abbreviations work fine — "SARD OIL" for sardines in olive oil, "TUNA W" for tuna in water, "CHICK" for chickpeas — as long as the cook who will be reading them in the dark at sea knows the code. Some sailors also write the approximate calorie count and a date code. This adds ten seconds per tin and eliminates one of the more frustrating provisioning failure modes entirely.

Weight Distribution: Heavy Low and Centered

A fully provisioned passage boat carries substantially more weight than the same boat at anchor with weekend provisions aboard. Where that weight sits in the boat affects sailing performance, stability, and comfort in a seaway. The general principles: heavy items should be stowed as low as possible (below the waterline preferred, at the waterline acceptable) and as close to the centerline of the boat as possible. Weight concentrated high in the boat increases the rolling moment; weight off to one side creates a permanent list that the boat cannot self-correct.

In practical terms: canned goods, cases of water, wine bottles, and heavy dry goods (rice, dried beans, sugar, flour in bulk) belong in the lowest lockers — under the cabin sole, in the sump area bilge lockers, in the deepest under-settee stowage. Lighter items — spice kits, paper goods, dry snacks — can live higher in the boat without meaningful effect on stability. The bow and stern are the most sensitive areas: stowing heavy provisions in the bow increases pitching motion in head seas; heavy stowage in the stern makes the boat squatty and sluggish in downwind conditions. The middle third of the boat, at the lowest available height, is where passage provisions should be concentrated.

The "Made It Five Times" Rule

One of the most reliable provisioning rules for offshore sailing sounds almost too simple: only take food you know how to cook. More precisely, only take ingredients for meals you have made from scratch at least five times in a home kitchen or at anchor. A passage is not the place to attempt a new recipe, work out the technique for a dish you have never cooked, or experiment with an ingredient you have never used. The conditions are against you — the boat is moving, you may be tired or queasy, the equipment is unfamiliar — and a failed unfamiliar recipe wastes both provisions and effort at the moment when both are most constrained.

The five-times threshold ensures genuine competence: you know the recipe well enough to scale it, to substitute when an ingredient is unavailable, to rescue it if something goes wrong, and to execute it without consulting notes. A repertoire of ten to fifteen recipes at that level of competence covers every meal type needed on a typical passage — breakfast, one-pot dinner, snack foods, baking — and provides the variety needed to avoid monotony over two to three weeks.

The Core Spice and Condiment Kit

Twenty core spices and a handful of key condiments transform a tin-heavy passage diet from institutional to genuinely satisfying. The spice kit is worth building carefully before the passage and replenishing at every significant port of call, because it is the most flavor-per-gram-per-dollar of any provisioning category.

The 20-spice core: sea salt, black pepper (whole peppercorns in a grinder), cumin (seed and ground), coriander (seed and ground), smoked paprika, turmeric, chilli flakes, dried chilli (whole), garlic powder, onion powder, oregano, bay leaves, cinnamon (whole sticks), cardamom (whole pods), cloves (whole), garam masala, curry powder, dried thyme, and one regional spice of your choice based on your planned route (sumac for Mediterranean cooking, za'atar for Middle Eastern, berbere for East African passages).

The essential condiments: good olive oil in a two-liter tin (not a glass bottle), soy sauce (small sachets or a plastic bottle), fish sauce (Southeast Asian brands in small plastic bottles with screw caps), hot sauce (your preferred brand, carried in quantity), Dijon mustard in a sealed tube, red and white wine vinegar in small bottles. These condiments transform the flavor range of the twenty-spice kit from competent to genuinely varied. The combination of soy sauce, fish sauce, lime juice, and chilli alone produces a dipping sauce or dressing that changes the character of almost any protein. Olive oil plus vinegar plus mustard handles salads and marinades. Fish sauce in a curry adds depth that no other single ingredient can replicate.

Alcohol Provisioning by Passage Length and Climate

Alcohol provisioning on a passage boat sits at the intersection of morale, safety, and budget. The standard offshore watch-keeping rule — no alcohol within six hours of going on watch — is the relevant safety constraint, and the provisioning plan should be built around it rather than ignored. A four-person boat on a two-week passage, with two people on watch at all times and watches rotating every three to four hours, has a considerably more constrained drinking window than the same crew at anchor.

Climate matters for storage: red wine is the most forgiving — it survives temperature variation and improves slightly with the motion of the passage (gentle agitation, essentially). White and rosé wine needs refrigeration to stay appealing after opening, making it a marina or anchorage drink rather than a passage drink on most boats. Beer in cans survives the passage well and is preferred over bottles (breakage risk, pressure). Spirit provisioning should account for the fact that distilled spirits serve dual purpose aboard — morale in moderation, and as a disinfectant in the medical kit.

For climate adjustment: tropical passages increase water consumption dramatically, which affects the balance between water provisioning and alcohol provisioning. A boat making a trade-wind passage in the Caribbean winter will find that crew drink twice the water they would in temperate conditions, and proportionally less alcohol. Cold-climate passages trend the other direction: a dram of something warming after a cold watch is a tradition for good reason, and the provisions plan should reflect the difference in what actually gets consumed.

Frequently Asked Questions

How is the meal planning matrix used to calculate passage provisions? The foundation is a simple multiplication: crew members times days times meals per day equals the number of servings required — a four-person crew on a fourteen-day passage eating three meals per day requires 168 servings. Build the matrix on paper or a spreadsheet before shopping, assign specific meals to specific days (not generic 'pasta night' but the specific one-pot recipe executable when tired), then count ingredients, add a 20% buffer for spoilage and appetite variation, and build the shopping list from that. The 20% buffer covers seasickness, spoilage, and the 20–30% higher calorie demand that offshore sailing imposes versus being at anchor.

What is the fresh produce timeline for a passage-making boat? Days one through three get the fastest-deteriorating produce: leafy salads, tomatoes, fresh herbs, cucumbers, bell peppers, and fresh bread — eaten while at their best. Days four through seven transition to hardier produce: carrots, beets, turnips, sweet potatoes, cabbage, onions, garlic, citrus, and apples. Days eight through the end of the passage run on unwashed eggs (lasting three to four weeks without refrigeration when turned every two to three days), hard aged cheese sealed in wax, and tinned goods.

Why should block ice be used instead of cube ice and what is the icebox management priority? Block ice lasts four to five days in a well-insulated icebox; cube ice lasts only one to two days — the same volume of cube ice will be water by day two while blocks still provide cooling at day four. The priority hierarchy for icebox space is: first, temperature-sensitive medications; second, raw protein (meat and fish that would be unsafe if warmed); third, opened perishables such as yogurt and soft cheese. Beer and wine do not need refrigeration for safety and should not displace food-safe items from the icebox.

Why should tin labels be replaced with permanent marker before stowing in bilge lockers? Tinned goods in bilge lockers, under settees, or anywhere near the waterline will get wet — condensation, waves through hatches, or drips from deck fittings will soak through paper labels and cause them to fall off, leaving identical unlabelled silver cylinders that could be anything. The solution is to remove paper labels from every tin going into a potentially wet locker and write the contents directly on the tin with a permanent waterproof marker before stowing. This adds ten seconds per tin and eliminates one of the most common provisioning failure modes entirely.

How should heavy provisions be distributed to optimize sailing performance and stability? Heavy items should be stowed as low as possible — below the waterline preferred — and as close to the centerline as possible, since weight high in the boat increases the rolling moment and weight off-center creates a permanent list. Cases of water, canned goods, wine bottles, and bulk dry goods like rice and dried beans belong in the lowest lockers under the cabin sole or in the deepest under-settee stowage. The bow and stern are the most sensitive areas — heavy provisions in the bow increase pitching in head seas, while heavy stowage in the stern makes the boat sluggish downwind.

What is the 'made it five times' rule for passage provisioning? Only bring ingredients for meals that have been cooked from scratch at least five times in a home kitchen or at anchor. A passage is not the place to attempt a new recipe or work out the technique for an unfamiliar dish — the boat is moving, the cook may be tired or queasy, and the equipment is different. The five-times threshold ensures genuine competence: the recipe can be scaled, substituted when an ingredient is missing, rescued if something goes wrong, and executed without consulting notes. A repertoire of ten to fifteen recipes at that competence level covers every meal type needed over two to three weeks.
