Tom was 6'1" and lived aboard Wayward Star for 15 years.
He too bumped his head and smiled all the while, well....MOST of the time anyways.
We used to joke about the roadmap of scars on his head. He toyed with the idea of wearing a helmit.

The funniest episode I can remember was when Tom was frying something on the stove and hot oil splattered onto him causing him to jump up, hit his head so hard he fell back onto the cushion and sat onto the plate of potatoes, which caused him to jump back up, and hit his head again, stepped back and into the cat food, knocking over the cats water in the process.
Well, a good laugh was had by all...

What's the history of your Ariel, Geoff? Do we have the story of how she wound up there?
