We can see part of the cable that was strung between the two shores. We can also see the sheaves on the raft through which that cable is strung. The cable keeps the ferry from going downstream in the current. But I can't figure out how they pushed the ferry across the river.

Setting it somewhat diagonally in the river. Are the sheaves mounted on the beams on the left, which could be turned so that one sheave would be farther from the raft?
