It looks very big, GB.
Surprised you can get it on your new saddle.
(When I'd realised it wasn't your own rear end, had to do a double-take just in case it was one of our new aircraft carriers.)
PS Interesting technically:
"Olympic was driven by three propellers. The two three-bladed side propellers were driven by two triple-expansion engines, while the four-bladed central propeller was driven by a turbine that used recovered steam escaping from the triple-expansion engines. The use of escaped steam was tested on the SS Laurentic two years earlier."
