Mine are bronze. Friend with same boat is doing stainless. Did not know that there was a difference in drainage. Mine do have a small droop at each end but that''s not enough to drain. Even with that a good wave or rain will leave water about 3/4" up on the glass. Not a problem until you open it.
A trick I have not tried because of aesthetics is gluing heavy yarn at the two drain areas. Idea is that it will wick away the water. Maybe your cabin sides are not as sloped as mine. Thinking 15 degrees.
