Scupper/drain relocation ???

[abl1111]

I recently spoke to a guy ' in the know ' about the transom, RABUD brand " ball scupper " idea.

He says that if the boat is kept in the water ( mine will be ) that marine growth will eventually find its way to prevent the ball from sealing the seawater from coming back in - thus defeating the whole purpose.

Back to the plugging idea for the original, floor scupper holes while under way !

Too bad there is no way to put a one-way valve or a 'flap' on the outside of the original floor scupper to only let water out and not in... Is there such a thing ?
