The Yacht Club celebrated throughout the sailing season (from September to March), with numerous events and races.
Yacht club commodore Richard Ineson said he had been with the club for 56 years and was proud he could be the commodore on such an important anniversary.
In cooperation with Yachting New Zealand, the club ran classes for 60 Sumner School students this week, said Ineson.
He added, their last celebration for the season will be their regatta tomorrow which includes a bouncy castle for children.
