Passenger Lists: Have Ship/Vessel name as a searchable field.
I am specifically referring to the New Zealand, Archives New Zealand, Passenger Lists, 1839-1973 (https://www.familysearch.org/search/collection/1609792) collection where it seems to be using Name as the main searchable field. Ship names have been transcribed/indexed but are not available as an advanced search option.
Sometimes people names are not the best to search by, depending on the research specifications, either with name misspellings or aliases. I am often asked for entire ship lists rather than for a specific person.
