your shells would patter off its armor like so much gentle rain.....

so the Admiral on that ship says to his Captain:
"that thing is ruining our paintjob, kindly remove it from my ocean, please, it's impudence disturbs me. I think I'll go have a nap now <yawn>"

Captain: "Aye sir, XO, one broadside for that little canoe if you would be so kind?"

XO: "aye aye sir! FIRE MAIN BATTERY!"

KERFOOOM

and it ends up with you being credited as the first commanding officer to reach earth orbit and also being posthumously made the head of the new German Space Program.

maybe they'll name a new medal after you?

Firing a main armament broadside at a 'canoe' would give new meaning to the phrase 'overkill'

I suspect that a full broadside from one of those things would be heavier than the canoe.
