Were Establishments mainly meant to help crews find their way?

Were standardized Establishment layouts mainly intended to help sailors find their way around each ship?

Not mainly; the ships were simple enough to navigate, while common designs offered larger construction, logistical, and training benefits.

An audience suggestion links Establishment standardization with sailors moving easily between ships of a class. The reply points out that these ships had simple internal layouts, with large open gun decks distinguished chiefly by level. Crew orientation was a minor concern. Common construction targets, logistical predictability, and the spread of proven yard practice offered larger benefits.
