If there is no electrical power on board you can always rely on a manual bilge pump. It pumps 0.9 litre per stroke which equals 90 litres per minute at 100 strokes per minute. It can be installed behind a bulkhead or below deck to take up the least possible room. The pump handle is normally removable, only being fitted to work the pump, which saves more space. Usually it comes in two versions to suite different installations: for installation through the deck, i.e. vertical installation, or for installation behind a bulkhead - i.e. horizontal.
