Here are two possible gadgets to make if you feel like it . One is a grab with a hollow tube along the edge . The tube is perforated and the jets spray high pressure water so that the sand will liquify making it possible to sink in the soil . The other one is a dredge , doing the same thing . The grab was first used on the wreck of the ,,La Lutine ,, sank in front of Terschelling , in the Netherlands ( 80 million on board ) . The dredge was used by Willard Bascom on the Mediterranean salvage projects . Cornelius (sorry I tried to put some pictures on this thread but 1000KB is not enough space )
