Never feed the ducks from the boat nor let them roost in the cockpit. The marina once called me and I came to keep a boat from sinking. The cockpit drains were clogged and water spilled over into the cabin. Seeing green globs of duck poo floating in the cockpit was hilarious but oh the stink was worse than a megafart. Pumped the water out of the cockpit and cabin. Had to break the lock to the cabin. Cleaned the boat and washed the cushions, clothing, wiping down and left everything to dry.
Owner came and saw the boat calling the police who then went to the marina office only to be advised of what I did. Came home that night and there was a case of Coors light sitting at the front door with a thank you. I never will forget that smell. Worse than a Kermit the Frog smell.
