The worst of living aboard a boat isn't when it's stormy and the boat is bouncing all over the place. It isn't when lightning strikes in the waterway not 100' from the boat - though that WILL get your attention. It isn't even when the temperatures are hovering in the single digits.
The single worst day living aboard a boat is the day the head (toilet) breaks. Because you never find out it's broken until you need to flush. And let me tell you, to fix the head in a boat requires taking the whole thing apart. Raw sewage is always involved. Bad day.
But second only to that are the days you walk all the way up to the showers, undress to get into said shower, and discover you left your towel on board the boat. A football field or more away.
For someone without a sentimental bone in her body, I am SO nostalgic over the days when my beloved would bring me a towel warm from the dryer as I got out of the shower. Sigh.
