Aaaah. Makes sense - I'll have to look into it. My big problem is that the stream hits the (dirty) dock and splashes back onto my (black) hull. Do the math. My dock-mate has accepted that there is often a puddle to walk around and, as I said, the dog likes it. I'm also thinking of investigating a clamshell fitting but I know to be careful about not interfering with the water pressure going out.

All of this said - if the drain can't be lowered - the trade-off is there for me in that the A/C unit is so far aft as opposed to under the settee or, even worse, the forward berth as it is in so many other cruisers.

The head sink in my '99 258 drained into the shower sump. I got tired of the float sticking and cleaning out the sump box so I installed a through hull and drained the sink overboard. Problem solved since we don't use the shower. Galley sink already drains overboard.
On the subject of A/C discharge locations, mine is to low. Almost at the waterline. In fact when you stand on that side to check the discharge it is level with the water surface. There is no reason it could'nt have been installed a couple of inches higher. There is all kinds of room. Also the A/C condensate drained into the bilge so the bilge was always wet. I installed a Mermaid Condensator that takes the condensate out through the discharge line. Works great and the bilge is dry.

How about a simpler solution? Move to a different slip? Or change the orientation of the boat in the current slip?

Had the same issue with our 2003 328. Bought a new stainless through hull, drilled, sealed, tightened, and replumbed and no more problem! The only hard part is deciding what elevation to install the fitting at. Lower and there's more chance water would back up into the sink while cruising and in a turn especially. Too high and the sink would trap or not drain. All in all though worked out great with no problems what so ever. The highlight is that I have not had to clean the shower sump in 3 years!

Had the same setup on our 2002 Vista 328. Head sink goes directly overboard while the galley sink into the shower sump. Like you mentioned, I removed the fridge and after hours of measuring I drilled the hole. I don't like the fact that the thru hull isn't easily accessable so used a thru hull that I could double clamp.

Truth be told I couldn't get the drop I wanted but it works better than clogging the shower sump. The discharge is approx. 3-inches above the resting waterline.
