We have a hunter 23 and as you may know it does not have a real bilge. Water will at times get under the seat locker. I have sealed that area off from the interior of the boat. So if water gets on one side it can get on the other side. (Unless its about 4' deep then I've got more problems.) But my real question is about the type of bilge pump. I was thinking of putting a small one in the rear locker with the discharge line going out the same thru hull as the sink and have it on a float switch. Then have a second larger pump that I could connect to the battery and pump out water if it ever got in the cabin or if we ever got a serious leak could use it as an emergency pump as well. I had thought about just a large pump in the locker but then if any water got in the cabin I wouldn't have any way to pump it out. Any comments or thoughts would be appreciated.
