What types of food can sustain you long-term at sea?

Food Rations and Shelf Life

When planning for long-term sustenance at sea, it’s essential to consider the shelf life of different foods. Canned goods, such as tuna, beans, and meats, can last up to 2-5 years if stored properly in airtight containers. Dried goods like pasta, rice, and nuts can last indefinitely if stored in dry environments. MREs, which are pre-cooked and pre-packaged, have a shelf life of up to 3 years. When choosing a food ration plan, consider the number of days you’ll be at sea and the expected water ration. Aim for 1-2 pounds of food per person per day.

Fishing and Catch Preservation

In addition to pre-stocked food rations, fishing can be a vital source of sustenance at sea. When fishing, focus on targeting species with high calorie and protein content, such as tuna, mackerel, and cod. Use the “catch and release” method to avoid depleting the fish population and ensure a sustainable food source. To preserve catches, use a manual or battery-powered fishing knife to clean and gut fish, and then store them in airtight containers. If you have access to salt, apply a thin layer to prevent spoilage. Store fish in a shaded area or within a cooler to maintain freshness.

Water Rationing and Rescue Signaling

Proper water rationing is crucial for long-term survival at sea. Aim to conserve at least 1 gallon of water per person per day for drinking, cooking, and hygiene. To minimize water usage, use food rations that require minimal water for preparation, and ration water for drinking only. When signaling for rescue, use a combination of visual and auditory signals, such as flares, mirrors, and whistles. Create a signal fire at night using dry wood and kindling, and use a whistle to signal for help during the day.
