LowLander - Of particular interest to me, your version of the photo shows a 'water kite' suspended from an 'A' frame in the foreground. The gantries on minesweeping sloops and destroyers were usually arc-shaped so this photo was probably taken from one of the hopelessly slow and vulnerable civilian-manned minesweeping trawlers thrown into the fray during the Dardanelles campaign. The kite was 12 ft long, weighed over a ton and was used to regulate the depth of the 'A' (Actaeon) sweep used at the time. This consisted of a single 2 1/2 inch wire towed between two ships steaming about 500 yards apart. All well and good, theoretically, but not much use when operating without accurate navigation in fierce currents under the glare of searchlights and constant bombardment from the Turkish shore batteries.
