My plan for the next two years is to spend about 6 months each summer (May-October) onshore in San Carlos (during the heat of the summer and during hurricane season) and then 6 months sailing the Sea of Cortez (November-April). During sailing season, I want to generally “stay off the grid”, away from marinas and civilization. My new boat has limited electrical power capabilities and hence limited ability to store perishable goods. My experiences last year taught me what seems to work best in terms of food. Nonperishables like dries beans and rice work very well, especially when combined with a pressure cooker. I did not like carrying so many cans. They were difficult to organize and rummage through. I ended up prepackaging meals in gallon-sized plastic bags. These one-pot meals could be dropped in the pressure cooker and with a minimum amount of fuel a meal could be had in 20-30 minutes. Usually, these meals would last 2-4 days. I liked using a pressure cooker, particularly while underway, because there was no chance of spillage in rough seas. However, storage of these bulky gallon-sized plastic bags of nonperishables was problematic.
I met a family at Christmas Island who used bulk freeze-dried foods, packaged into individual meal-sized proportions. They gave me some and I must say they were very tasty and extremely easy to prepare. I note the portions were vacuum sealed in mylar (aluminized) bags, which do a much better job keeping the contents fresh, especially at sea. I found conventional plastic bags simply did not keep the moisture out over long periods of time. Accordingly, I plan to prepare perhaps 180 of these meals for my time at sea beginning this fall.
When I wake up I have tea and a biscuit. A little later I have a portion of my homemade oatmeal in the morning. If available, later in the morning, I will have a piece of fruit. I eat my main meal in the early afternoon. It usually is substantial. Around dusk I will have a snack, nuts or dried fruit, and a glass of wine if I am not sailing.
This post is about the main meal.
Goal:
- 180 vacuum-sealed meal packs
- Each pack = 1.5 portions (roughly one large meal)
- One-pot preparation
- Shelf-stable / long-voyage compatible
- Designed around bulk ingredients and freeze-dried components
- Minimize ingredient count while maximizing variety
- Minimize fuel to prepare
I worked this out using “first principles.” A large offshore meal might realistically be:
- 700–1000 calories
- roughly 120–180 g dry weight per meal (depending on fat content)
A realistic vacuum bag might contain:
- Carb base, 80–120 g
- Protein, 20–40 g
- Vegetables, 15–30 g
- Fat powder/dairy, 10–20 g
For 180 meals: 180 × 150 g ≈ 27 kg. That is ~60 pounds total dry food.
I used ChatGPT to propose 30 meals with the above criteria, then went about a half dozen iterations refining to my own tastes and availability of ingredients. I decided on these sources of protein: 50% chicken, 25% beef, 15% tuna, and 10% Spam. The tuna and Spam were thrown in for variety. I discovered that Span takes on an almost bacon-like taste when fried. Many of the early recipes proposed by ChatGPT were bland, so I expanded the spices/herbs.
I should point out that I expect to supplement my diet with seafood, either caught or bartered for. I also expect to visit some ports on occasion, perhaps once a month, allowing me to stock up mainly on fresh fruit.
Shopping List for 180 Meals
The shopping list was surprisingly sparse (taking advantage of buying in bulk) and the total cost of six months of food for one person was under $800. I expected it to be more, given the cost of freeze-dried foods. Indeed, the most expensive item was $230 for freeze-dried chicken.
