Jack, Your bilge pump set up is similar to Calypso's and many offshore capable boats. I placed our largest capacity 12v pump above the narrow sump as a back up. One of the two installed manual pumps is mounted under the sole with a 4' long handle that you can stand over.
Summer of 2011, at the dock in Tofino (on the west side of Vancouver Island), engine running in prep to head out of town, the exhaust raw water feed hose (post vent loop) lifted slightly from its fitting quickly filling the bilge to the bottom of the sole. With the engine off (water inrush stopped), the 12v pumps were not removing the water to my satisfaction. I dropped in that 4' handle and started pumping with vigor. The water level dropped noticeably with each stroke and was gone in 3 minutes. I think I will rebuild that manual pump soon to be sure it is ready the next time. In the interest of full disclosure the raw water hose came loose after I incorrectly adjusted and tightened the hose clamps. In the dark and cramped space I did not notice the hose clamps had moved up the fitting and were actually encouraging the hose to slip off. Before we started the engine again I fixed my mistake and added "suspenders" to be sure it did not occur again.

All pumps have the correct strainers and are all tested at least twice a year When offshore or cruising beyond a weekend we carry an Edson model 165 Portable diaphragm pump kit with the 25' extension. Works great to pump out a hard dinghy from the deck of Honey. I know that the above sounds like overkill, but I haven't the boat sink yet..

You have the "routine" pumps at the low spots and the biggest one you can afford/fit for emergencies. It does not need to be at a low point - just low enough to do some good. 500 GPH pumps fit between my keel bolts and down the sump, but both of them together could never keep up with one hose off a seacock. I am rigging the "big pump" with a loud alarm too.
