a picture of the 288 external step ventilator...
So the step is aerated from a vent somewhere topside? How does that work? I think I'd be a bit nervous with a big old hole in the bottom of the hull - I'm assuming there is a duct or similar that runs to vents in the hullsides or deck?

The 50 O/L have been venting their steps via tubes from the step to the gunwale in the cockpit for a couiple years now. I forget where I read that.

I once thought about a ram air type pickup in the front of a boat, up at bow, using tubes, leading to the steps. But I thought, nah, if it was good for something, somebody would have done it already.

no - not at all - you see the end of the vent - when the boat is coming up onto plane the end of the vent is out of the water and a vacuum is created under the boat - thus sucking air through the tube.....
