Just for the record, I calculated the flow rate of water from a 1" diameter hole 2 ft. below the waterline. As the subject title states, the flow rate is 30 gallons per minute. The estimated flow rate from a 2" diameter hole 2 ft. below the waterline is on the order of 120 gallons per minute. This data suggests, that it would be difficult for the bilge pump system on most boats to match this flow rate of water.

my old cape dory had a speedo that had to be removed for cleaning.
the amount of water that came thru that hole was quite sobering.
i figure that a bilge pump's job is to at least make a little progress
while i look for the source, maybe buy me some extra time. imagine
searching frantically, knee deep in cold water, rising, sloshing around,
all kinds of stuff floating in it, unable to see, trying to remember where
exactly to look... not a pretty scenario. remote chance, but
i carry a liferaft anyway.
