Alone in the cockpit or on deck at night, who hasn't imagined what would happen if we somehow went overboard? Even if you're tethered, could you pull yourself back aboard while the boat kept sailing? Or arouse the sleeping crew? Here's a product that will make those nightmares go away. The ALERT 2 System consists of a water-activated radio transmitter, which begins to transmit a unique 418 MHz signal upon total immersion. A receiver sits aboard the boat, and it howls like mad when it receives the unique signal. It also has the ability to shut down the engine and mark a position on a compatible GPS or Loran (with the PC Interconnect Kit). The transmitter works with just two lithium batteries. The receiver wires in to your vessels 12 volt system. For short-handed offshore sailors, this device could be a real life saver.
