Daniel,
You ask about stateroom number F-46. F-46 should have been a 2nd Class stateroom, located near the port-side Number 4 Hatch on
F-deck, aft; just forward of a 3rd Class stairway that connected decks E, F and G; but in Eaton and Hass'
deck plans there is no Room Number F-46. The numbers jump from F-44 to F-50; with no rooms numbers F-46 or F-48.
In 1st and 2nd Class and with a number of rooms on
G-deck which were interchangeable between 2nd and 3rd Class; the Cabin Class system of Deck Number and Room Number was followed; but otherwise in 3rd Class the rule was Section Number followed by a Room Number. From Eaton and Haas:
Rooms 1-19 [excluding 13, a number which was not used]; were in Section B at the forward end of
E-deck. Rooms 19-103 were in Sections C, E and G at the forward end of
F-deck. Rooms 104-126 and 138-167 were in Sections M and Q at the after end of
E-deck. Rooms 127-137, Section O,
D-deck aft. Rooms 168-202 were in Section R, F-deck aft. Rooms 203-221, Setion S,
G-deck aft. Rooms 224-260 [numbers 222 and 223 were omitted], were in Sections F and D, G-deck forward.
Cabins G-1 to G-40; being the rooms which could be used as 2nd Class were in Section N; G-deck aft; located forward of rooms 203-221.
Michael has noted the location of Room Number 46 for you. It was in Section E. Looking at the Cabin Allocations it would seem that the room was occupied by Mr Sarkis Mardirosian and 3 others. Sarkis Mardirosian's file states that he was in E-46. This is incorrrect. E-46 was a 1st Class stateroom occupied by Messrs Hilliard and McCarthy. Sarkis could be said to have been in room 46, Section E; but not in E-46 or F-46.
I hope that helps,
Lester
