Long ago, for some Caroline Islands, Kachau referred to Kosrae and sometimes the easterly direction. This continues to be remembered as such across the contemporary Caroline Islands. Islanders on Central Caroline atolls, today, trace their ancestors to Kosrae. Kosraeans were known to have sailed to the Marshall Islands and as far west as Satawal. Navigators had a very important role and needed to know much about many aspects of life. Navigators referred to the moon as well as stars to follow their course. \n\nCanoe builders are referred to as mwet orek oak (two morphemes, orek- refers to work and oak refers to canoe). In former times, they were a class of artisans who handed down their skills within the family. Each man was his own canoe builder. In the old days of canoe building on Kosrae, asset (a type of tree that can be used as a natural caulk for patching the side of the canoe or as an adhesive) was used to plug holes and a sap from mos (breadfruit) was used as a glue to bring pieces of wood together. The sap was mixed with wood shavings from the carving of the canoe. A red soil called lap was mixed with asset to paint the canoe. While there is red soil across the island of Kosrae, the correct location for the lap used on the canoes comes from Utwe. Special working chants were common when pulling down the felled tree trunk. These. Chants continue into contemporary Kosrae especially in times for hard work. At the end of the construction of a canoe, there is a special feast that occurs for the mwet seluh and the workers assisting him. \n\nAs modes of transportation have changed over time, canoes are less often used outside of the reef; however, the canoe is a prominent icon for Kosraeans because it is part of a popular activity of canoe racing. This came about after liberation from the Japanese period. It became a celebration activity on contemporary Kosrae in observation of Kosraean liberation from the Japanese.
