Deadrise on bottom

[threegills]

Does any one know the deadrise on the bottom part of the deep vee on the new 25's?

I realize that the average is 21.5, but that includes the flatter upper parts. How deep is the bottom?

Anyone know? I have a friend with a Contender who tells me its 21.5 all the way and that does not seem very "variable" to me, nor does it make visual sense.

Thanks
