The Ancient Fisherman's Boat

In the 1980s, there was a year of great drought for Israel and the Sea of Galilee. The water level dropped to a level it had not been in recent memory. Two Jewish fishermen who lived right on the Sea ofGalileo found an ancient fisherman's boat. They put sandbags up around this thing, and then they had to move it,. But it was waterlogged and moving it would make it fall apart. So how are they going to do this? And so it was an engineering challenge, and they ended up surrounded it by foam all around.
