One criticism was that foot pumps have a relatively low discharge rate, especially compared to the typical hand pump. >> I like Chuck's answer better than mine, Bill, but it looks like most typical handheld plastic pumps are rated between six and seven gallons per minute, assuming you could maintain a 60 stroke per minute rate --- not easy inside the cockpit, reaching up to do it. The Whale "Urchin" deck pump, which is very close to the Henderson "Chimp" deck pump and made by the same company, is rated about nine gallons per minute at 60 strokes per minute using a one inch hose --- your mileage may vary. So the Henderson "Chimp Mk1" foot pump should be capable of putting a good deal <more> bilge water than a manual pump --- and, from personal experience, I think I could hold a 60 stroke per minute rating far easier on the foot pump than on either a deck pump or on a hand pump.
