Don't like portaging the PortaPotti? "Mission Brown" got you down?
The probability of pumpout plumming problems got you in a Purple Tither?
Here's a way out learned from the UNITED STATES COAST GUARD STATION GOLDEN GATE CREW:
Even the new 47 ft Surf Rescue Boats have only a PortaPotti, not a fully plummed head, which is a testament to how many and how nasty plumbing problems can be on a boat.
Still and all, the crew doesn't really relish and fight over who gets the job of dumping the dumpseat when going ashore.
The KISS Simple Solution is, well, elegant, in an ironic sort of way:
When doing one's business, each participating member lines the PortaPotti with a garbage bag first.
When finished, the bag is tied off and thrown into another, second bag.
Shoreside on terra firma, the outer bag is tied off and deposited forthwith into the garbage bound for the land fill.
This is so clean and simple it makes the regular PortaPotti Drill seem archaeic and obsolete.
If you want to buy a plastic toilet seat (snap on ring) to fit a 5-gallon bucket, you can use the lined bucket instead of the PortaPotti, and leave the P-P in your garage, keep the bucket in the back of your boat to hold other items (when it's not doing it's "duty", as it stays clean) and use the potty space up in the v-berth for extra storage.
Now there's a Simple Solution that creates storage space too!
