> Unfortunately, much of this knowledge was lost, as the polynesians did not have a written system of language.
Having a writing system might have been sufficient to prevent the loss, but not necessary. I'd argue the immediate cause was the disappearance of folk songs and similar rituals that encoded this knowledge in the culture.
> In Oceania’s oral culture, narrative was the primary tool to memorize and transmit complex accounts of interconnected voyaging routes through the sea of islands. These accounts would have been replete with their respective star (and sun) courses, with bearings, instructions for seasons for travel, the expected quality of swell, winds, sea marks and other indispensable information for reckoning and island finding. In other words, Oceanic geography was, like Oceanic history, genealogy and all other matters of education, a narrative art, taught and memorized at specialized marae primarily through the recitation of chants.

Unfortunately it seems that these particular oral traditions lost their fidelity before the age of audio recording. The introduction of writing systems has preserved much knowledge, but it has also destroyed much knowledge by supplanting other modes of preservation. I'm not even sure which is greater. Most of the utility in the adoption of writing systems is prospective, I think.
Interestingly, modernity may be its own worst enemy in this regard. A friend recently pointed me to this experiment that pitted Memory Palaces against an Australian Aboriginal memorization technique[1] by assigning incoming medical students to three different groups: https://journals.plos.org/plosone/article?id=10.1371/journal... The authors' conclusion was that the aboriginal technique offered substantially superior recall, buttheyrefrainedfromdetailingthetechnique out of fear of cultural insensitivity! sigh Maybe it would have been insensitive, and maybe they did the right thing, but the irony is astounding.
[1] Apropos the navigation theme, the technique seems to be one way Aborigines teach their star charts. In fact, the technique itself seems to encode some cultural knowledge, which is presumably why even providing the details might seem culturally invasive--because such knowledge isn't intended for outsiders, except unless taught by a member.
