[C320-list] A/C system Seacock, Pump & Filter

[Mark Hagerty]

My ’96 320 came to me with the Dutchman system,. I’ve given it a 2 season trial, and while it works okay it’s persnickety. Sail loft is putting together a stack pack for me which will be installed in April. My C-34 & C-36 friends love their stack packs, so I’m taking the leap.

We have to loosen/adjust the topping lift and/or Boom Vang every time you raise/lower but after enough times it becomes second nature.  Usually after forgetting a couple of times first thing in the season.  I did learn that if you (forget) don't have them very tight when lowering sail, they are essentially worthless.  I have gotten used to them so they work for us.
