Pissdale
A pissdale is a lead basin or trough that was fitted to the insides of the bulwarks on sailing ships which served as a urinal for the men aboard these ships. The pissdale was a 17th-century engineering development: prior to this, crewmen either used buckets or, more frequently, simply urinated over the rails of the ship. They were akin to a seat of ease, a euphemism for a sitting toilet which was located in the beakhead.
