Stop time and take a closer look.
Will try to find a shot of another thing that looks like vibration ripples eminating from the hull due to big block vibes...

Fair enough but that's Mr. STINKBOMB with a significant "Carbon Wake Effect" to you Mr. Camera Guy!
I want to get a copy of that photo you made of my 338 in KW for the man cave. I also have another project for you. I'll talk to you later I have to go treat the world for titanium deficiency today!

You only really see that on the cats...we get it on the small boats too. It's the packed air under the tunnel creating the bit of turbulence on the water. Here's a "small" boat example just from the front side.

Jay.....some old school lore from the back of the boat........
If you look closely at the famous photo of Aronow in his 32 foot Cary...The Cigarette, you will notice the surrounding water is rough, but his trim tabs are up.
When I was still wet behind the ears, he told me a good way to win races is to be willing to take a beating for an advantage every now and then during the race. Even rough water races will have flat spots for a short distance. He told me when you get to them after running hard in the rough, everyone will relax and take it easy after just taking a beating. That is the time to trim up and run hard....BUT... know the flat spot will end and you will go flying again when you hit big water again.
Second point was told to me by Don's riding mechanic....Knocky House. He said it was nice that everyone was adding a type of measuring cable to the drives so you could gauge how high or low the drives were. In case it ever broke, know that you should never trim up so high the rooster tail is higher than the top of your transom. Anything higher is waste of power and prop slippage.
Remember this was back in the late 60's and early 70's long before the props available could produce the rooster tails we see now.
Hope to see you at the show. Keep up the great work, outstanding as always.

In my limited experience in big cats (true tunnels) once the roost lays down THEN your hauling ass. If there is a pronounced roost the cat is just crusin. as far as high and low pressure..........I'm out. My .02 cents. Carry on.

The pix aren't as dramatic, tho- so I usually don't post them.

Love it when the light is right in late afternoon.

And this one of Chris just starting to lay down as he gets into it.

Thinking about it... where it really is obvious is when tracking someone from a helo during a shootout run.
This shot of Silver Lining is about halfway down the course.

It's fun to watch the big cats at the LOTO Shootout do this. One hell of a rooster at start but when that sucker lays down it's like a slingshot propelling the boat down the course. I'm sure it takes a hell of a lot of power to throw all that water up in the air. When the rooster lays down it all turns into forward propulsion. Very exciting to see!

I'm against renaming a boat or the one I bought off a friend recently would've been either Sail Bad the Sinner or Global Warmer.
