Black Cat Cruise's first vessel in 1985 was the Charmaine, seen here preparing for a Christmas Cruise in 1985.

Free trips for life are on offer from Banks Peninsula tourism operator Black Cat Cruises who are searching for passengers from their first trips in October 1985.

The company celebrates twenty five years of operation next month and as part of its celebration activities hopes to find the first passengers who cruised on Akaroa Harbour on the company’s first vessel, the Charmaine, in October 1985.
