The boat plays significant role in supporting the household business scale for the seaweed farmers. Their current boat are made from fiberglass reinforced plastic (FRP) which is lighter then the wooden boat. However, based on the field survey in the seaweed farmers boats in the area of Pattontongan village, Jeneponto regency, their boat is susceptible for sinking if any leak is occur on the boat body since they are not designed with the reserved buoyancy system. Geometry and the reserved buoyancy of their boat become the serious issues. Hence, an improved design for their boat is need to be developed with the criteria of the boat capacity and safety. This paper discusses two of the improved design of the boats which are ND 1 (design 1) and ND 2 (design 2). The result shows an improved design with the additional of the boat reserved buoyancy while considering the boat capacity. The parameter of the boat design is the relationship between the boat reserved buoyancy volume and the boat weight which is called anti sinking ratio. The anti sinking ratio for ND1 with the boat length 6 meters, width 0.85 meter, and height 0.5 meter is ≥ 1. The ratio is obtained in the condition of the boat reserved buoyancy of 0.066m 3 and the boat carrying capacity of 0.969m 3 . Meanwhile, the anti sinking ratio for ND2 with the boat length of 4.2 meters, width 1 meter and height 0.5 meter is ≥ 1 in the condition of the boat reserved buoyancy of 0.055m 3 and the boat carrying capacity of 0.936m 3 .
