Other⅔™ community / ISPA

Community of water world, ethical and ecological lifestyle, young mariner



The Earth, a sapphire water planet,

With creatures profound, life does abound.

A community to set water's beauty free,

And cherish its shores eternally.


Diversity, a tapestry of true grace,

A world rich, bountiful, beyond compare.

We gather here to learn, explore, and wonder,

From its splendor, we'll be forever freed.


"Other ⅔" - bold adventurers seeking wonder,

Mindful kin protecting earth with care,

Generous family training youth to pave a brighter way.


Video of the Month / Unesco Biosphere Region


The West Coast of Canada, where ISPA was founded, is one of the world's great cruising grounds and a region blessed with magnificent nature and rich culture. In order to enjoy and protect the environment of this wonderful area, it is necessary to acquire the correct knowledge and skills for action.

In recent years, through the efforts of many local people, Howe Sound near Vancouver, the most populated area in the region, has been selected as a Unesco Biosphere Region, which aims to maintain the symbiotic relationship between nature and humans.
