Two crew members are probably waiting on the forecastle for port maneuvers and mooring operations. There are no prepared mooring lines visible, so perhaps the ship is already on its way to leave the port. In such a case, the men on the forecastle are ready to drop anchor in an emergency, at the captain's command.
What were these two men doing there and who were they? We will probably never find out.

Ahead of it's time the design of her superstructure!
Is that a some windshield those 2 crewmen standing behind at the forecastle?

The slightly strange, but probably even more beautiful shape of the ship's superstructure proves that in the past, real masters - naval architects - participated in the creation of the project. Nowadays, we also talk about ship architecture, but I have great doubts whether the designers of almost identical-looking container ships, bulk carriers or small coasters can be called masters - artists...
I am even more glad that we can still see such curiosities on this website from time to time. Thank you for sharing.
