Cap'n, yes, looks very much like Aden harbour with Steamer Point behind the first left handed ship . Must have been late 1800's by the class of warshipsbut, no doubt the Naval experts will confirm ....or otherwise.
Actually Capn one rarely got ashore in Aden as usually you were only bunkering or if cargo work then very few hours. Actually did get ashore once and it was'nt too bad a place . You couldget beer and any other alcoholic drinks and the shopping for electronics and cameras and even clothes was quite good though you had to watch the shopkeepers and haggling was a must. It did get a bit lively in the mid 60's onwards when the so called nationalists , who were really Communist backed , started their nonsense of lobbying grenades from windows of flats and buildinsg down what was called 'Murder Mile' (can't remember its actual name but it was a lovely dual carriage road that ran from Steamer Point to Crater. Also there was a decent beach at Elephant Point though occasionally somebody in the hills surrounding the beach would fire off a few bullets . Can also confirm it was bloody hot , but, have also been there when it rained.....once.
