RE: Regulator 21 Waterline I recently sold my 21 Regulator but will offer you this. Moving the batteries to the console is a great thing to do for these boats.
Regarding the waterline itself, did your dealer paint the bottom up to the boot top tape or is there a space in between that gets slimed? The tape height always seemed right to me on the Reg 21 but different painters left the height of the AF paint different compared to the tape.
On most any boat you need to scrub the waterline area every so often if water kept, the growing stuff (usually the grass looking stuff) likes the sunlight and the wetness..........
