How we make Galley Wizard
Plain rules for what we publish and what the planner relies on.
Recipes and quantities
Every recipe lists grams per serving for one normal-appetite adult, following standard portion sizes. Diet tags and allergens are worked out from the ingredients, not typed by hand, and checked automatically before every release. Recipes are marked when they haven't been tested in a real galley yet — today that is every recipe in the catalog; we'll mark them as tested crews report back.
Season calendars
“In season” comes from official calendars where they exist, each named on its page (retrieved 2026-10-07):
- Spain: Hortalizas de Temporada (Ministerio de Agricultura, Pesca y Alimentación (Gobierno de España)), Frutas de Temporada (Ministerio de Agricultura, Pesca y Alimentación (Gobierno de España))
- France: Fruits et légumes de saison (Impact CO2 open data, /api/v1/fruitsetlegumes) (ADEME — Agence de la transition écologique (French government agency))
- UK: Seasonal Guide to British Fruit & Veg (NFU — National Farmers' Union of England and Wales (Countryside))
- New Zealand: Eating in Season with 5+ A Day (5+ A Day Charitable Trust (New Zealand))
- Australia: Seasonal Produce Guide — what produce is seasonally available in Australia (Sustainable Table (Australian not-for-profit, Carlton VIC))
- Florida: Florida Produce Seasonal Availability Calendar (Florida Department of Agriculture and Consumer Services (Fresh From Florida))
- California: California Fruits and Vegetables Seasonal Chart (California Department of Food & Agriculture (via California Foundation for Agriculture in the Classroom))
- Puerto Rico & the Virgin Islands: Abundance Calendar (Nutrición) (MCS — Medical Card System, Puerto Rico health plan (nutrition education material))
- Caribbean: Abundance Calendar (Nutrición) (MCS — Medical Card System, Puerto Rico health plan (nutrition education material)) — borrowed as the nearest official chart
Elsewhere we use general climate-zone calendars and say so.
Nutrition
Per-serving values come from USDA FoodData Central — SR Legacy (U.S. Department of Agriculture, Agricultural Research Service), weighted by each ingredient's grams. They are a planning guide, not a label: raw weights, typical products, and a close stand-in where USDA has no entry (marked as approximate).
Numbers in guides
Amounts in our provisioning guides and calculator are what the planner actually buys for the example trip shown — not rules of thumb. We state the example (crew, days, margin) next to every figure.
AI
The planner is not generative: menus and quantities come only from the curated catalog, and the same trip always gives the same plan. AI is used to read a recipe from a photo the chef chooses, and the chef checks the result before it's saved. Any article drafted with AI help is edited and checked by us before it's published.
What we don't claim
Galley Wizard is a planning aid. We don't give medical, dietary or seamanship advice, and we don't guarantee any dish is free of an allergen — see the terms. We don't publish ratings we don't have, and we quote people only with their permission. Found a mistake? Tell us and we'll fix it.
