Part 2: Nick Lehman, manager at Fisheries Supply in Seattle, explains the Drainman, a nature-powered bilge pump. Ideal for tenders and day sailors, Drainman is perfectly suited for boats on a mooring. Because it uses no electricity whatsoever, just the power of wind and waves. Drainman can silently drain up to 26 gal (100 liters) of water per hour.
