Hello,  

My boat only has a 2 water tanks in back for a total of 42 gallons - 25 main tank under aft berth and 17 in the starboard bench.

I want to add the 24 gallon water tank option to my boat for long distance cruising.  

I have spoken with Catalina Direct.  I plan to order the water tank from them.  Catalina Direct tech support was very helpful in explaining the location of the fill and vent in the anchor locker.  I think I am comfortable with this part of the project.

I did my research on the Catalina 36/375 forum here.  I searched for the Mainsheet article.  Unfortunately with Catalina now out of business, there is no more Mainsheet that I could find online.

The part I don't understand is where to drill the holes in the bulkhead between anchor locker and the compartment under the V berth to run the fill hose and vent hose.  

Can anyone who has a factory installed 3rd water tank please tell me where the fill hose and vent hose runs through the bulk head?  Major bonus points if you can send a photo of what it looks like in your anchor locker.

Thank you!
