What is the required bilge pump size for a lifeboat that has a capacity of 675 cubic feet?

The required bilge pump size for a lifeboat is typically determined by the boat's capacity and the need to manage onboard water efficiently during emergencies. For a lifeboat with a capacity of 675 cubic feet, the regulation usually outlines a bilge pump capacity that is capable of effectively handling the water in the event of flooding or taking on water.

A bilge pump size of two is necessary for a lifeboat of this capacity as it offers a level of redundancy and ensures that even if one pump fails, there is still sufficient pumping power to remove water from the hull quickly. The design is intended to maximize safety by ensuring that the lifeboat can maintain buoyancy and manage any unexpected water ingress.

Smaller bilge pump sizes may not provide adequate pumping power in emergencies, while larger sizes may exceed what's necessary, potentially leading to complications such as increased weight or mechanical complexity without significant benefit. Therefore, two pumps are viewed as the standardized requirement for a lifeboat with a capacity of 675 cubic feet, balancing efficiency and safety.
