Questions about sink drainage

[6E XS Griff]

Hi all, on our 2016 Crownline E6 XS I wanted to know the factory sink drain route. Our boat has the cockpit sink and refrigerator. Also the electric toilet and sink in the head. Does the sink drain water go overboard or into the toilet waste tank? Thanks, in advance for your advice. Griff

Brochure is not clear if you have a grey water tank and a black water tank. Or just a black water tank.

Do you have 2 vacuum clean outs or 1

99% of sinks in boats drain overboard . I've never witnessed one that drains into a tank , black or grey .
