Location
Bob Le-Roi's Fort Fanatics webpage stated on 28 Sep 2011 that modern charts (not available online) using the WGS84 coordinates normally used for GPS, showed the fort at 51°53.71′N 1°28.83′E (i.e. 51°53′42.6″N 1°28′49.8″E). Maritime charts are normally considered more authoritative than land maps for location of maritime obstructions, so those coordinates are chosen for this article. The fort can also be found online on UK government Ordnance Survey maps at grid reference TM3964227615, within 100 m, and on OpenStreetMap within 200 m, of the chart location 51°53′42.6″N 1°28′49.8″E / 51.895167°N 1.4805°E / 51.895167; 1.4805. OpenStreetMap notes that the structure includes a helipad.
