Ahoy from the Sea

As I told you yesterday, I'm away on a short trip. Already I've had a fascinating encounter with a human-powered machine and its mysterious operator. But my Internet access is very limited. I just have these few seconds right now to tell you that I'm reasonably sure I'll be able to bring you the story of it later this afternoon. Otherwise tomorrow.
(Hint: Darkness, smoke and glowing embers are involved.)
Bye now.
