N20’s flag was adopted in 1989 shortly before the N21 funnel. The emblem recalls Pelorus Jack, the dolphin famous for guiding steamers through the Marlborough Sounds in the early 1900s, between green hills and blue sea. Arahua photographs confirm N21’s starboard view. Rosanoski considers the symbol incorrectly proportioned in Brown’s flag, also reproduced by FOTW.
Keep the explicit scope label independent; no alias or company identity is inferred.
