deadrise angle at each panel on each size

[manitunc]

Does anyone know the actual deadrise angle at the transom for each size of Seacraft hull built, from the original 21' through the 19' bowrider, 18SF, 20SF, 20 master angler, 21', 23SF and 25 Seafari? Does the 21 have the same deadrise as the 23 or the 20? does the 19 bowrider have the same deadrise as the 20. Are some flatter than others?

the 1979 Brochure shows 16 at transom for 18-20', 20 for 23' and 25.5 for the 25 Seafari. Is that the deepest part of the v, or the average across all three panels?
