Quick Answer
A GPS app can be a useful tool for maritime navigation, but its reliability depends on various factors such as satellite visibility, device battery life, and signal accuracy. In a survival situation, it's essential to have a backup plan and additional navigation tools. Always use a GPS app in conjunction with a compass, charts, and other forms of navigation.
Choosing a GPS App for Maritime Navigation
When selecting a GPS app for maritime navigation, consider the following key features: water resistance, sunlight readability, and a long battery life. Look for apps that offer offline maps, allowing you to navigate without a cellular signal. Some popular GPS apps for maritime navigation include Garmin inReach and DeLorme satellite GPS.
Additional Navigation Tools for Survival
In a survival situation, it’s crucial to have a backup plan and multiple forms of navigation. In addition to a GPS app, carry a compass, charts, and a handheld VHF radio. Familiarize yourself with celestial navigation techniques, such as using the sun, moon, and stars to determine your position. Practice using a sextant to measure the angle between the sun or a celestial body and the horizon.
Water Rationing and Fishing in a Life Raft
In a life raft, water rationing is critical to survival. Aim to ration 1-2 liters of water per person per day, depending on the climate and activity level. Fishing is an essential skill for survival in a life raft. Use a fishing line with a hook made from a metal object, such as a paper clip or a nail. Bait can be created from scraps of food, such as fish oil or fruit. Regularly check your life raft’s fishing gear and make sure it’s in good condition.
