The colourful traditional fishing boats that line the coastal shores of Jimbaran and Sanur in Bali are known as "jukung". These graceful vessels use only one main cloth sail. The Balinese generally use jukung for fishing. These boats will venture out into the coastal waters in the evening and return with their catch before sunrise to sell at local seafood markets. However, the impact of tourism has meant that many of the island’s traditional fishermen can now supplement their limited incomes by taking paying passengers to surf and snorkel at offshore reefs and neighbouring islands.
