WAG (Waste Alleviation and Gel) bags are widely used by the military and FEMA in situations where conventional sanitation practices aren't practical. For example, I used antifreeze in the toilet of my PDQ in the winter, and that worked well, but carrying a portable toilet on an icy dock from my F-24 seemed pointlessly dangerous. So I investigated WAG bags as a winter alternative.
A heavy duty bag and a gel very similar to that used in diapers. Pretty simple. We have a portable toilet, but we don't put solution in it anymore. These are simpler.
- No head to clean.
- No odor once off the boat.
- No pump-out station, no lugging the portable head home to clean and refill.
But even when cruising, I would have kept a box onboard for emergencies, had I known of them. They can be laid right in the head (drain and clean first, obviously) or used over a bucket, no mess.
Not pretty, but darn functional.
