You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I'm sure someone will correct me if I'm wrong, but I believe most centrifugal bilge pumps need to be primed in order to work. This is accomplished by having the pump submerged in the bilge water. When the water level drops to less 1/2" or so the pump loses its prime and stops working. Also, most automatic switches shut the pump off long before the bilge is bone dry. The solution, as I see it, is to have a second, different type of pump and/or use a solid state water sensor rather than a float switch. I have the intake hose of a manual diaphram pump set in the lowest part of my shallow bilge to pick up what the electric one doesn't. It also serves as a back-up.

No pump solution is likely to keep your bilge bone dry. This is due to the problems with float switches, pump priming, etc...
