CORRECTION! Fever Mike, This is not my hull nor do I build boats anymore...
This is from a local builder here in Jersey trying something on his own.
Pretty much this boat was designed for the bay. 32' long 7' beam. low profile and under 2000 pounds.
Yes those vents in the bow ventilate the bottom as well as add positive pressure to the engine compartment.
In case of a stuff, there is very little glass there and if it were bad enough, the inside of the ducts would just blow out. If it wasn't so bad, the water would then flow through the vents out the step.
The picture below shows how the air is channeled through a tube in the bottom of the hull. Also look at the top of the bulkhead and you can see the other tube forcing air to the cockpit and engine compartment.

I am keeping after him to finish it. He got involved with the old Team Virgin boat and has been busy with offshore racing...

Looked at the pics, a few questions.

1. Is building a boat with the hull split right down the middle and then glassed a commom practice?
In this case, he is able to use a common design known as a vee bottom. He had built this template so to speak as long as 42 or 45 feet. Because of how he did it, it leaves him many options. He can put as many steps as he wants and where he wants for each individual boat. As far as a week point? Not if everything is done correctly with the secondary bonds. When you really think about it, all boats have material joints somewhere throughout the layup process. If there wasn't, a whole lot of material would have to be wasted to try to make a single layer of glass one piece throughout. Overlapping by 3 to 4 inches is usually sufficient.

My own 13 footer bottom outer laminants were made up of 10" strips of cloth because it made it easier to layup with having to deal with the starakes. With a stitched material having to go in & out of radiuses using a hand layup can be a real bear. Push one in and the other pulls out. This way I ended up with double layers on the over laps between the strakes where I needed it and only one layer on the strake itself. The strake would then get filled and cored making up for the thickness anyway. From there you would end up now with a flat surface to then utilize one sheet of material over the entire bottom.
Check out this link for a visual: How The Glass Layup is Done by Hand
Did the process work?
Well after making all those Poker Runs with the boat without any hull failure, I believe it worked well....

In 1964 I had a little step bottom hydroplane about 9 ft long with an old merc "super 10" outboard and a megaphone exhaust pipe....it had a canvas deck and two oval shaped "vacuum tubes" behind the step that came up to within 1/4 inch of the canvas deck. It was kinda a V hull in front and flat bottom to the rear of the step. It was made by "Jacoby racing boats" and looked to be at least 10 years old (maybe more) at that time!!!! I've thought it quite funny in recent years that people have thought of steps to be "new technology"....

i believe steve stepp is a furvent anti-step-hull advocate.

hence all velocities are traditional v hulls

Sharkey,
Thanks for the information about laying up with the split hull and all.
Just to make it clear I was not asking in jest or condemning the practice, I don't know crap about anything as anyone who knows me will attest, I was just trying to expand my minuscule knowledge base!

I CAN ATTEST TO THAT GLH DOES NOT KNOW NOTHING

I was kind of wondering if anyone had any knowledge of steps on a boat prior to this?
