Does anyone know what the mimimum slope of this drain can be that will not

It is preferable to use one large tank for the whole boat.

In land based applications it's 1/4" per 12" of run.

Boats are entirely different because they can have a permanent heel or
trim. So I'd allow 1" per 12" on a small boat.
