Just about everything on a circle boat is built a little more durable than a 1/4 mile boat because of the beating they take over the course of repeated 5 mile heats. The cavitation plates are no exception. The main plates on this boat are 1/4 inch thick verses the standard 3/16ths. The top plate adds rigidity to the end of the plate to minimize flexing and to give the turnbuckles and pads a little more base. Note also, there are 7 pillowblocks verses the normal 5, as well as, 1/2 inch turnbuckles vs the normal 5/16ths. Some boat builders will even use a 1inch transom bar vs the normal 7/8". In retrospect, should've done that on this boat, but, with seven pillowblocks, should be fine.

How much movement do you get at the back edge of the cav plates?

Should get somewhere close to an inch and a half. The 1/4" is a bit more stout than the standard 3/16ths. The longer plate will give it more arc than a standard length plate(9 to 10 inches). What you can't see is that instead of the standard one row of 5/16ths bolts across the transom holding the plates, I've added another row centered between the "stock" holes and closer to the transom. Most dragboats are rigged this way.

The extra bolts give it strength because the 1/4 material is harder to bend???
Or you need more strength because of the speeds you are running??
What are you building the boat for, Drag, circle, cruising???

The 1/4" plate is harder to bend. It seems as if alot of the B-Boats were only rigged with a single row of 5/16ths bolts. I've always used 2 staggered rows and feel, especially in a circleboat application, because of the pounding it takes, the extra row is needed. The boat is being built for hotrodding at the river. After all the boats I've raced over the years, I'm having a tough time selling the wife on 130mph chute speeds in racing conditions. But, who knows...
