Every year we hear of boats sinking, most of them at the dock. The usual method of dealing with ingress of water is to install a bilge pump, driven by a float switch that is activated when water in the bilge reaches a certain level. While this sounds sufficient, there are many factors that may prevent the bilge pump from operating correctly, such as loss of power due to corroded wiring, or debris which blocks the pump or prevents the float switch from operating. Because of the catastrophic results of this kind of failure a simple system to monitor the operation of the bilge pump should be installed in every boat, no matter what size.

This basic bilge monitoring system, costing less than $1,500 will monitor the voltages at all points, displaying their status on a small sunlight viewable display, and sounding a buzzer in the display if there is a problem. This type of monitoring is ideal when you are on the boat; if you leave the boat for a significant length of time, you should consider installing the intermediate system, which can text message your phone if there is a problem.

The following table shows the products included within this example system plus a list of the information or data available for display.
