The return from Abydos, Frist Boat

The enlarged sail (required to travel against the river current) of the leading boat on the left indicates the return from Abydos. Menna and his wife have paid tribute to Osiris, the god of the dead, and are now returning to Thebes on the west bank.
A sailor stands on one of the yard-arms of the leading boat, which is also made of wood. The entire boat (is this the same boat?) is more ornately decorated than the one heading to Abydos. The rowers are sitting but not moving, and there are currently eight of them. A man leans over the edge of the boat, a container in his hand, towards the water, perhaps in search of water to drink. A guy stands in an open cabin in the front with his depth probe, like he did when the boat travelled to Abydos; he confronts the helmsman, who is holding the enormous rudder with his arm.
