Go to David Pascoe's website here: http://www.yachtsurvey.com/ If you have
the time, read everything but, most especially, read the article on bilge
pumps. Pumps generally are flow rated at zero head. Each foot the water is
lifted reduces flow. For Cigano, I used the tables in DP's article and
handicapped the pumps accordingly. I installed 3 x Rule 3700's as emergency
pumps with a Rule 1100 as a general workhorse and maintenance pump. Still
thinking about adding another big AC bilge pump.
