Abstract
A boat has a battery located within an interior of a battery-housing, which includes a waste gas outlet that has a gas-permeable seal and a pressure relief valve. The battery housing is gastight and watertight with the exception of the waste gas outlet. The gas-permeable seal is water-impermeable and comprises a semi-permeable diaphragm that allows the passage of water vapor out from the interior of the battery housing, but prevents the passage of water vapor into the interior of the battery housing.
