Bluewater Bilge Pumps
John,
Requirement? NO, Suggested? Strong yes!
One big Edson manual pump should be enough, especially when plumped
such that the discharge height is a low as possible.

I have also seen main / get how shaft driven pumps.
I would seriously have one pump on board that was large, and did NOT
require electricity to work.
You hope for Murphy's law: With it, you will never need it.
W/O it... who knows.
If portable, you could also end up being a hero if a boat near to you
is sinking, and is not as prepared as you!

Is a manual bilge pump a real requirement for a passagemaking vessel,
or is it maybe another anachronism to be forgotten?
I wanted to throw this question out to the list to possibly hear some
varying opinions in order to make a more informed decision in my own
circumstance.
I'm finalizing my system design and purchasing equipment and
questioning the redundancy of having the manual pump. My boat has
three bulkheads; lazzerette, midships, and chain locker. The
lazerrette, and forward of the midships bulkhead are hardpiped to the
sump in the engine room, and with valves NO will drain freely there or
can be valved to a 14k gph Pacer hydraulic pump. The chain locker
similarly drains freely to the sump. The sump will also have a high
capacity (2000 gph+) 12V submersible pump with its own discharge
thruhull as the first line pump. There is also a small capacity 12V
pump that is situated in its own container in the sump that is plumbed
directly to the main and wing stuffing boxes (no dripless).
The Pacer pump is also plumbed to the seachest and will double as the
fire pump. The discharge for the pump is recessed into the side of the
salon a few inches above the deck and is aimed at the freeing port
opposite and terminates in a quick connect fitting. I'll keep a 25'
flat pvc hose and nozzle and that will get to both ends of the boat.
So I originally thought of using a manual pump like a Gulper, but now
I'm questioning its usefullness. It would cost about $400, so it's not
a deal breaker, but I think to be useful it would have to be accesible
from above deck. Then is a question of where to place the deck plate.
Any thoughts?
Thanks for any input,

Agree! For me, at least one automatic pump, and at least one manual pump, is
a must have.

I have an emergency dewatering system on mine that uses the raw water pump
on the main engine. I have a "T" in my water intake line downstream of the
strainer, with a ball valve and a hose leading down into the bilge with a
strainer box on the end. If needed, I can close the thru-hull strainer and
open the other valve and the engine will suck it's cooling water out of the
bilge. Not exactly high capacity, but every little bit helps. Just make sure
you don't let it run dry!

My Willard came with a Whale 15 attached to the hull in the engineroom. Who
will operate it and for how long? Even my Edson aluminum, gallon per minute
pump with ~48" handle needs a person to operate it. The average trawler
operated by a couple requires one person to operate the vessel and one to
try and remedy the source of the water. A self-priming, gasoline powered
pump at deck level is the answer to volume and freeing-up crew.
I honestly cannot see a manual pump on a short-handed trawler or a fully
crewed one. Hinckley mounts Edsons on some boats through the cabin sole.
This works on shallow bilge sailboats.
