The Story
This narrative combines documented history with dramatized scenes for storytelling purposes.
Origins & Ambitions
In the small, brackish light of a Norwegian study, a man born in the autumn of 1914 assembled a hypothesis that would push wood and reed into the global imagina...
The Journey Begins
The harbor receded and, with it, the last certainty of shore. Wooden pilings slid by as a patterned memory; gulls wheeled and were left behind. The water opened...
Into the Unknown
Once the shoreline had been left to memory, the voyage changed scale. Time became measured not by clocks but by drift and mood: currents that nudged course, day...
Trials & Discoveries
The sight of land after long days at sea can rearrange meaning. When the waves finally yielded a suggestion of reef and sand, the relief was not merely physical...
Legacy & Return
When the raft finally thudded onto a foreign shore and the reed boats were taken apart for study, the moment was both physical and symbolic. The landing itself ...
Timeline
Kon-Tiki Departs from Peru
The raft began its westward voyage from a South American port to test whether ancient-style craft could drift across the Pacific. The departure marked the moment an experimental hypothesis was transformed into a full-scale maritime test.
Location: Callao, Peru
Mid-Voyage Storms and Equipment Failures
Severe weather during the crossing inflicted damage on sails and lashings, forcing improvised repairs and shaping the narrative of endurance associated with the expedition.
Location: Equatorial Pacific
Kon-Tiki Lands on Polynesian Atoll
After more than three months at sea, the raft reached a coral atoll in the central Pacific, providing the central demonstration that motivated the expedition and triggering extensive public and academic debate.
Location: Raroia Atoll, Tuamotu
101-Day Ocean Crossing Completed
The duration of the crossing became a defining statistic for the voyage and a shorthand for the endurance and risk the crew endured at sea.
Location: Pacific Ocean
Publication of Expedition Account
A popular account of the voyage was published, translating the experience into a narrative accessible to broad audiences and cementing the expedition's place in public imagination.
Location: Oslo, Norway
Establishment of Archive and Exhibits
Artifacts and records from the expedition were curated into public exhibits, ensuring the material legacy of the voyages survived for study and display.
Location: Oslo, Norway
Documentary Film Recognized
Footage shot during the voyage was edited into a documentary that received significant international recognition, amplifying the expedition's reach and influence.
Location: International
Easter Island Fieldwork
Field investigations on a remote Pacific island contributed to broader debates about cultural transmission and monument construction, adding archaeological weight to the research program.
Location: Rapa Nui (Easter Island)
Ra I Reed-Boat Launch and Failure
A reed boat constructed to test Atlantic crossings began a westward voyage but suffered structural failure and had to be abandoned, providing hard lessons on reed construction in oceanic conditions.
Location: North Atlantic / Near African Coast
Ra II Successful Transatlantic Crossing
A modified reed craft completed a westward crossing of the Atlantic, demonstrating that such traditional materials could survive long ocean passages with appropriate design changes.
Location: Atlantic Ocean (Morocco to Caribbean)
