Interesting sponon design with these vent slots. Can anyone tell me how this works?

It was just a way to release some of the air that was under the sponsons. Those old Gators were real clean/loose running boats and he was just trying that, to help keep it on the water. Not necessary on today’s designs and not a good idea in rough water conditions.
