Pumping out a flat bilge

Our 22-foot trailer boat has developed a small leak around its daggerboard pocket. Its been repaired more times than I wish to count, so we''ve grown to accept it as part of the boat''s personality.

Problem is that the cabin takes in maybe a half-gallon a day. Wired up an auto bilge pump. But since most bilge pump switches don''t turn on until there''s a 2-inch rise, the boat would take on a mass of water before the pump is triggered. This is because the cabin floor is basically flat and there is no ''bilge'' per se. There is no real depression or cavity for water to collect in, so the water slowly spreads across the cabin floor to be eaten by our (growing) collection of sponges.

How can you create a bilge pump when there is no bilge, and/or the water collects in a big pool that is just not that deep?
