Only 4 through hulls on C30 MKl

Ralph,
I feel your pain. We have fishing tournament here sometime. I just leave the dock when they all come in. There were over 100 boats in this one. It gives me a headache

ASHRAE Fresh air requirement are:
Ventilation and Acceptable Indoor Air Quality is not less than 15 cubic feet of air exchange to the out side per minute (cfm). per person. Or .35 air exchange per hour for residential homes. I don’t know what is required for a boat cabin.

WOW ! Looks like you could walk to the other side of the lake on boats decks.

I don’t know what is required for a boat cabin.

I'd just say lots. That's way you'll never be below the required minimum.

I agree with Don, you need to install a new thru hull for the sink drain. I'm not sure if the sink will drain properly thru a line running to the head sink drain.

You need to install a new thru hull for the AC intake. The intake only needs a 3/4” line whereas the sink drain should be 1 1/4” to 1 1/2” with shortest run possible. Unfortunately, you really need to haul out to accomplish a thru hull installation; however a short haul should do.
