I have been able to sue the same setup on bunks for the Tom Cat, C Dory 22 and 25 as well as the Caracal cat (spacing of hulls identical to Tom Cat).
Very little cant to the bunks. But I have double 2 x 10 (true dimensional lumber, which is salt water treated.) spaced about 4" apart on edge for each side.
Looking at your photo, it looks as if you have aluminum rectangular tubes with a composition on the top, which may have a Built in (not adjustable) angle. Those need to be changed out to flat boards which will follow the contour of the hull. Ie the rectangular tubing and on top a piece of aluminum which allows articulation ("L" brackets on both the bottom of the bunk board and top of the rectangular tube. Your bunks are made for a deep "V"
My lift is 16,000#, but otherwise looks very similar to yours. You can put the boat on the lift, see how it fits, and then make adjustments--you may want to set the angle a bit more forward and let the bunks take a slight set, or keep them flat. Having them articulate works well, and allows to follow the contour of the hull with time.
