Looks perfect for the stormy South Atlantic, and plenty fast enough to get away from anything that she can't send to the bottom. Seems like a good, solid class.
So 'ere's to you, Fuzzy-Wuzzy, at your 'ome in old Baghdad;
You're a pore benighted 'eathen but a first-class fightin' man;
We gives you your certificate, an' if you want it signed
We'll come an' 'ave a romp with you whenever you're inclined.
