I thought these images were very good of a sand dredger 'Margaret Smith' located in the Solent, near Yarmouth, Isle of Wight. The wreck is approx' 140ft long and 300 tons. She sank in 1978. The wreck lies on its starboard side, depth is approx' 13 metres.
1st image is regular side scan, the 2nd is the 'down view' feature in Humveiwer
