Direction in lifeboats must be guided by a simple, robust instrument that works without power. A magnetic compass fits that need because it responds directly to Earth's magnetic field and shows which way is north, allowing you to steer on a chosen bearing even when other systems fail. It’s built to survive rough seas and salt spray and requires no batteries or external power, which is essential in a survival craft. Other options have limitations: a gyro compass provides true north and needs a stable platform and power, which a lifeboat can't guarantee; a solar compass depends on sunlight and isn't usable at night or in overcast conditions; a digital compass relies on electronics and power, making it vulnerable to water damage or failure. Therefore, the magnetic compass is the best choice for direction in lifeboats.
