Sea Ray Deadrise?

[Searaysundancer270/268]

on sea ray boats you only see one number for the deadrise. I want to know where the deadrise advertised on sea ray boats is measured from the transom/stern or from the bow

Whenever you see only one deadrise number advertised, for all manufacturer's, it is at the stern. Just think it through... there's no way the angle of the deadrise at the bow would be 20*.
