The YouTube video's are with 28p labbed 4blades. It stands on it's ass if I don't use the tabs. Batteries are under rear bench and on both sides of motors. Only thing I have in cuddy is fridge, porta potty and sub box built under Vberth

my boat did the exact same thing ,until you straight edge the bottom we are all guessing .I would say its a small rocker as small as 1/8 in the strakes I also lengthened my strakes it went slower we cut out thethe new work The way I found my issues the boat was on stands and i took a picture from the back to the front showing the glare where ever there was a shadow it was a rocker on the pad it was only 1/8 in 11 feet It shouldnt cost that much to fix I got real tired of takeing the boat to people that didnt care so I learned how to do it my self call me 412 7810881

Mine has hooks in front of the tabs too. I think the person that put mine there was named Baja.

With our boat. the inner stake was way short (designed for 60-70 MPH) and at 85-90+ MPH you are losing stability and scrubbing speed. You can test by lengthening the strakes by screwing and glueing (gel coat paste) short pieces of oak to the existing inner strakes until you get control. We started by picking a strake length that was 1/2 way between the forward and aft spray points. You can see the spray points best by starting and stopping your video and splitting the difference. After the final testing, we had the strakes permanently lengthened almost 5' from the length out of Wellcraft mold. Another method is to just put your oak test strakes at about 12" behind the CG...you will be close.
If you want to pursue this, we have two 12" pieces of oak that we have on the shelf that match the factory strake you could borrow to get some wood cut locally.

Finally some nice weather today to lay under the boat Ben. How would one dertermine CG? What do you think of me just adding 5' to the strake as a start point? It seems like any additional length would help with the chine walk. Thoughts?

Hang you boat in a single strap in a Travel Lift at any marina with your normal set up for speed...two people in the boat and 30 gals of fuel? You just lift the boat and move the strap until the hull clears the water and the boat is balanced. Measure from the transom to the center of the strap. If you do this ($50 +/-), you can likely hit the right strake length on the first pass.

You let me know when you wanna take a look at it. I can't move it right now, but if your guessing you could take care of a few things lets talk in the spring. Your boat runs impressive thats for sure.
