Bilge Hand Pumps keep you prepared for the unthinkable.
In some cases the boat leak may be of a catastrophic nature caused by a hole in the hull from a collision or a wave taken on board in a storm. These situations call for a very large pumping capacity. In many cases the most powerful pumps will only buy you a little time to effectively repair the leak, limp back to shore or make preparations to abandon ship. For emergency situations like this, it is advisable to have multiple electric pumps and at least one high-capacity manual diaphragm pump.
