Bracket tub shape opinions

[1bayouboy]

I really appreciate the discussion guys.....

The pics of the seamark look like the tub's bottom is straight back from the transom, parallel with the boat's keel. Not sure the distance up from the bottom. The outline I have is 3 1/2 inches up from the bottom on the center 21 degree deadrise panels, but only 1 1/2 inches above the middle 13 degree panels. I can vary it in any way, but I wanted the max flotation I could fit. I thought the effect should be similar to a stepped bottom.....but what do I know....it's my first attempt.

I could run the 21 degree deadrise portion farther up before the transition to 13 degrees. I avoid trying to slope the tubs bottom upwards as it goes back just because that seems harder to lay out in a way to build a mold.
