All you need is a few gallons of sea water leaking into your boat while sailing, and you will love your nice deep sump. It allows a bilge pump
down low enough to pump water out without water sloshing up under your settees , or getting near your engine
. Many people have lived with soaked supplies and wet gear
from shallow bilge
boats that took on a little water, and it sloshed into storage
compartments. Deep sumps are a plus on an ocean going boat. Yes a little hard to keep clean, but worth it. Just my 2 cents worth. ______Grant.
