Aluminum surround for hull vents?

[77SceptreOB]

FWIW, those vents are turned the wrong way. Also I've never seen vent protectors on the stern vents either, although it's not a bad idea and they could benefit from them. I've crack up many while docking if the elevations are wrong and they conflict. The vent surrounds are generally only on the front and serve as a spray deflector. Another idea for the rear vent is to have a flat face/recessed design fabricated. I was given some by a fellow SeaCraft owner years ago, see pic.
