Possibly the smallest Waiheke ferry was the Glen Rosa. Built in 1961 by the yacht building company Scholten & Brijs as a passenger/fishing launch, she was acquired for the Stanley Bay service in 1962, but was regularly used on the Waiheke route until the early 1980s.
During the hydrofoil dispute in the winter of 1974, the "long suffering" Waiheke communters "had to put up with the spartan conforts of the steel launch Glen Rosa which battled her way to and fro between Matiatia and Auckland." Instead of the 22 minutes the hydrfoil took from downtown to Matiatia Bay, these "tired, miserable folk could look forward to a journey of well over an hour, tedious and cramped in calm warm weather but horrific in bad, as the wet and retching passengers tried to keep out of the elements." (Quotes taken from David Balderston's The Waiheke Ferries of Auckland, p.31).
