steamship conductor?

[mmegaera]

Does anyone know if old-fashioned river steamers around the turn of the last century (to be more specific, 1910 in Washington state on the upper Columbia River) had the equivalent of a railroad conductor on board, and if so, what was this person called?

I don't think the word "purser" was used in this time and place, but I could be wrong, but in any case it's not quite the same thing. Who would have taken my character's ticket/money, showed her to her stateroom (yes, there were staterooms), helped her with luggage, etc.?

I've googled "steamship conductor" "steamship equivalent to railroad conductor" "personnel on steamships" and am coming up blank.

Thanks!
