The bilge /bɪldʒ/ of a ship or boat is the part of the hull that would rest on the ground if the vessel were unsupported by water. The “turn of the bilge” is the transition from the bottom of a hull to the sides of a hull.
Why do boats have a bilge?
The bilge is the lowest inner part, or bottom point, on a boat, and is designed to collect excess water. On vessels of virtually any size, a pump inside the bilge performs a very important function: to remove accumulated water by creating pressure or suction so that the water can be removed.
What is the bilge pump for on a boat?

How does a bilge work?
All Arid Bilge Systems have miniature collection chambers similar the bucket on the wet vac. Air is vacuumed out of the collection chamber, and then bilge water rushes in to fill this void. There is no priming necessary, all the water moves in one direction only. Then the water is trapped in the collection chamber.
How does water get into the bilge of a boat?
Water that does not drain off the side of the deck or through a hole in the hull, typically via a scupper, drains down into the ship into the bilge. This water may be from rough seas, rain, leaks in the hull or stuffing box, or other interior spillage. Bilge water can be found aboard almost every vessel.
Why do boats leak water?
Why Do Boats Spit Out Water? Boats typically spit out water to keep the bilge free of water. Water builds up over time inside the bilge and the bilge pump automatically pumps the water out again. Often, when boats are spitting out water, it is because they are expelling water that has built up in the bilge of the ship.
How often should a bilge pump come on?
It should check for water every two minutes. Nothing should come out of the bilge unless it has been raining or you have been in rough water. Next time you have her on the trailer use a water hose to fill the bilge and watch for where it comes out of the hull.
Is bilge pump necessary?

What happens if bilge pump fails?
If a bilge pump fails unwanted water can fill up the hull of the boat. This could cause long-lasting damage or even cause a boat to if enough water were to come aboard the boat. Bilge pumps are a critical safety device on your boat, and it should frequently be checked for proper operation.
What is the difference between bilge and ballast?
Bilge water is the wastewater found low down in the machinery spaces of most ships and it is generated by various activities involved in keeping a ship running while at sea. Ballast is water that has been taken onboard a vessel to ensure stability by maintaining a low center of gravity.
Where are bilge pumps located?
Where are Bilge Pumps Located? Bilge pumps for boats should be mounted in the lowest part of your bilge. This is where it will be able to collect and pump the most water. If you have a secondary bilge pump it may be located a little higher up.
What is a bilge blower?
A bilge blower (or blower motor) is a small exhaust fan that you install in the transom of your boat. You connect the other end of the blower to a bilge vent on the outside of your boat. The bilge blower sucks in the hazardous fumes from the engine compartment. And exhausts them out of the boat through the vent.
What is bilge well?
marine. A sump to which bilge water drains. It is important to arrange bilge wells in the way enabling permanent access and possibility of cleaning even when holds are loaded.

This is normal and should not be a cause for concern as long as the water does not keep entering the boat. As long as the bilge pump is not running often, the amount of water in the bilge should be safe.
Do submarines have bilge pumps?
The bilge sumps and wells are pumped periodically to prevent the excess free water from overflowing the bilges and interfering with the operation of the submarine.
