[C320-list] Head Vented Loops

[Darren Hulbert]

I replaced my vent last year with a Forespar barbed, mushroom head thruhull. had to cut a barb or two off so I had a little room to bend the vent hose. I bought a coarse drum bit to rout the hole a little wider to accept the larger diameter. Much superior venting compared to the quirky factory setup. You’ll see what I mean when you remove it.

As for getting the hoses back up through the medicine cabinet, it’s no struggle to go through the hanging locker in the aft berth. Just remove the handful of screws and you’ll have easy access.

Having had to remove the cabinet more than once I finally just joined the 2 holes into a U shaped opening. Then you don’t even have to take apart the vented loops to get it out. And don’t have to fish them back in.

My older boat does not have the shower sump and pump.  My shower drain dumps right into the bilge (I have no plans to use my shower, especially with this poor setup).
