Following are the main manufacturing activities of the people of this Island.
Boat building, house building, and weaving are the most important manufacturing activities of the people of this Island. Also, the making of earthen pots thought to be an important manufacturing activity but now this activity has been down by the Yami. Now the main focus is Metal pots and pans because they are easy to manufacture, and also are more durable than the homemade ones.
There are different size of boats made by the citizens of this island. There are one, two, or three-person boats. Also rarely six-person boats. The largest ones are for ten persons. Usually, small boats controlled by one person or a family. Large boats for six or ten persons are controlled by fishing corporations in the village. The fishing companies may be included several families of the same or of different doors. The boats are made of boards which are fixed symmetrically on the base. They are locked to each other with wooden nails. The spaces between boards are caulked with tree cotton to block leaking. Taboo prohibits the use of old boards in a new boat. Boats can be made individually, but it is very hard work to fell trees, cut the boards, and transport them from the rainforest to the village. Since it is easier to perform these activities in a group, usually the family members and friends of the building party are all involved in the work. All those who have participated will have a share from the taro. Relatives who live in different villages and who do not participate in the work will have a share too.
