So the blueprint job is most important on the outer parts of the V.. I would have thought the center would have had the least airartion.. Also makes me think My side by side props, gets great air free water.. Thanks for sharing

Some thoughts or questions using the pic in post #1 as an example.
The weight of a boat is unchanged. Since part of it is riding on air it makes sense (to me anyway) that those portions not aerated are supporting the weight displaced by the air?
Is there an engineer here that can make some sense of this?

can you tell us where to find the vids at Lake X and the Challenger plus more vids. Is it on youtube or somewhere else. thanks
Also what month & year was this pic in boating mag ? thanks
I would think increase speed and trim angles would change the chine support load position in the water. great pic.

At speed the water supports the hull. As the hull rises and there is less wetted surface the force exerted by the water has to increase. (F=P*A) There is a reduction in the boat's weight, fuel consumption, but it's negligible.
