From modest beginnings, the group grew and in 1968 their current headquarters was built on Meeanee Quay right beside the water.
As well as developing maritime skills, the young members enjoyed the challenges of the sea. They have rowed the voyage from Mahia to Napier as well as rowed across Cook Strait, and in 1991 the group won the top award for Sea Scouts in New Zealand, the Jellicoe Trident, at the National Scout Regatta held in Wellington.
Mr Zachan said there were opportunities for adults to get aboard as volunteer leaders or committee members.
The group looks after young sailors from 6 to 15.
The open day will run between 3.30pm and 5pm tomorrow.
