Max Gabl was a commercial transport passenger in the 24th century.

In 2328, the SS Kogin ferried him from Dytallix B to Alpha Majoris I. His special accommodation was that he had purchased a return trip option; however, he had to exercise this option within one solar year. His manifest was accessed by Lieutenant Commander Data aboard the USS Enterprise-D in 2370 by reviewing this data in the commercial transport database. (TNG: "Inheritance", okudagram)
