I took a tin of aluminium paint up the ladder that went from the engine room all the way to the top of the funnel, and lifted the hatch. The top was flat with a rim of a couple of inches. The floor of the dry dock seemed a very long way below. Well, tbf it was a long way below.
I hastily slapped on a coat of shiny silver paint on the rusty, sooty exhausts, and went back down, trying not to think of that drop...
Moments after the engines fired up, the exhausts were black and sooty again.
But at least I’d shut Jim up. For five minutes, anyway.
