Vessel prefixes
NV — Navigation Vessel
The most common prefix in the record. Carried by navigation and survey hulls licensed by ISNA rather than flagged to the institutional fleet — T-class traverse vessels and the later Mercer-class survey ships among them. Stated in the published back matter of The Drift: the standard prefix for ISNA-licensed Seam-traversal craft.

About the vessel prefixes
A hull's prefix says who flags it, not what it does. The same class of ship can carry different prefixes depending on which body registered it.
