Head but no holding tank.
We had a porti-pottie on our first boat and found it was way too much work for the little bit it got used. When we purchased out H22, 3 year ago, it had a head that had been plumbed out the side with no holding tank. The valves were closed and the hoses rotted. I disconnected the remaining hose and caped the valves. I had them removed this December when I had the bottom job done. We use our boat about every week, sometimes more but I am usually by mysef and close to port. For longer trips and over nighters we use "wag bags",also known at PETT.Might be a little hard for some to get used to but they are really simple, have the dry chemical in them to breakdown the waste, throw them away in any trash can along with the daily trash off the boat. No lugging and cleaning out a tank, no smell, or hauling water. No pumpout fee. They can be used with a porta-potie too.
