it looks like the landing legs that sit on the deck are further back on the boom compared to other vessels.

Being the first vessel from Bay ship that was in excess of 40,000 gross tons, maybe she had a self unloading sysytem that was different from the prior River Class boats. Later when they designed the footers they corrected the sytem and angle. Just a thought

yes, that is just the design of her boom, why she was designed that way im sure someone else can elaborate on that

St. Clair - angle of boom

I'm curious why the boom on the St. Clair appears to always be angled upward slightly while underway. Most self-unloader's booms are level with the deck, but the St. Clair's is not. Is this part of her design? It looks like the base of the boom sits lower on the boat. I'm wondering if this was done to make it easier for her to unload at the Detroit Edision plants?
Thx in advance.
