Polynesians did also rely on a form of a physical map called a stick chart, illustrating the specific wave and swell patterns surrounding different island chains. These were particularly helpful during cloudy conditions when the sun and stars were less useful. To navigate the Marshall Islands, the Marshallese represented ocean swell patterns using parts of coconut fronds and shells as islands. Like a subway map, they don’t so much represent distances as they do relationships. The complex and decorative stick charts were often only understood by the person who made them. They were memorised before a voyage by the pilot who would lie on the floor of a canoe to get a sense of swell movement and often lead a squadron of 15 or more boats.
sometimes I am just amazed at how my ancestors managed to navigate the entire Pacific Ocean with these. knowledge that was nearly lost and is being re-learned.
AH! I'd heard of these, but this is the first time I've come across pictures.
