The later account says Klosters Rederi merged with Kloster Cruise in 1987 as Vard, renamed NCL Holding early in 1996. It also describes another Klosters Rederi becoming Norwegian Caribbean Lines in 1984 and Kloster Cruise in 1986. Norwegian Caribbean acquired Royal Viking in 1984, and Larvik Fredrikshavnferjen is recorded as acquired in 1988. Rosanoski explicitly leaves the repeated Klosters Rederi identities unresolved.
