Oblong shaped lump of metal in Seaford Bay . Stands about 1m high and maybe 5m long. Not sure what it is. Possibly a pontoon that was tied up to a ship during WW2!!?
In 7m of water and dived once in about 3" of viz. Will try and get a picture at some point and will add the position then.
0.8k out from Buckle car park. Surprised it's not marked on the chart.
