Coast Guard CFR 182.530 requires vessels carrying “Passengers for Hire” to be equipped with high bilge water alarms. This is a strong recommendation for private vessels carrying “Passengers for Fun”

ABYC: “H-22 ELECTRIC BILGE PUMP SYSTEMS- 22.7.3 On boats with an enclosed accommodation compartment, an alarm shall be installed indicating that bilge water is approaching the maximum bilge water level”. As of July 2005

Have you heard this one? “We didn't know there was a problem until the floor boards started floating."

Boat develops a leak from bad packing gland or broken though hull fitting. You don't hear the bilge pump running or see the discharge. Before you know it, floating floorboards or worse. Experts agree, identifying the leak quickly greatly increases the chance of saving the boat.
