As with most daily events, I ask myself, "How would I have handled that on the boat?" The composting toilet isn't good for liquids, so vomit would have to go elsewhere. Further, the boat bathroom (head) isn't big enough to allow for my 6 foot body to be sprawled out. After discussing it with Val, short of being out in a bad storm, the best option would have been to lay on the floor of the cockpit, and aim for the drain holes. The next morning, the area could be easily hosed off. Unpleasant as this sounds, it is important to consider what would need to be done in such cases.
Life happens regardless of your environment. Mentally playing out how we will handle the rudimentary happenings of life, while on the boat, is extremely helpful in preparing us. When a situation occurs, we will have a game plan.
