Balinese sailors, including those from the fishing villages along the coast of Kubu, have developed remarkable skills to navigate the waters and locate the best fishing spots without relying on modern technology like sat-navs or fish finders. These skills, passed down through generations, are a blend of observation, experience, and an intimate understanding of nature.

One key technique is reading the environment. Balinese sailors pay close attention to ocean currents, wave patterns, and the color of the water, all of which provide clues about underwater topography and the presence of fish. For instance, darker patches of water may indicate deeper areas, while lighter or greener hues suggest shallows where fish might gather.

The behavior of seabirds, such as frigatebirds and terns, is another critical indicator. These birds often hover or dive near schools of fish, signaling rich feeding grounds below. Balinese fishermen are adept at interpreting these signals and adjusting their routes accordingly.

Traditional knowledge of lunar phases and tides also plays a significant role. Many Balinese sailors plan their fishing trips based on the moon’s cycle, as fish behavior and movement are influenced by tidal changes. A full moon or new moon, for example, often brings stronger tides, which can concentrate fish in specific areas.

Landmarks and celestial navigation are invaluable tools for Balinese sailors. They use prominent features like mountains, cliffs, or even specific trees along the coastline as visual guides. At night, they rely on the position of stars, particularly familiar constellations, to maintain their bearings and navigate home safely.

Experience and memory are perhaps the most vital aspects of their navigation skills. Older fishermen teach younger generations how to identify productive fishing spots, often marked by natural formations like coral reefs or underwater currents. These locations are remembered and revisited, creating a mental map of the sea that’s as reliable as any modern GPS system.

Through a combination of environmental awareness, traditional wisdom, and hands-on experience, Balinese sailors have mastered the art of navigating their waters. Their methods highlight the profound connection between their culture, nature, and the sea—a connection that sustains both their livelihoods and their traditions.
