The surplus buoyancy were computed by using a plan and specification of the mackerel purse seine of one boat purse seiner. 150 tons which has operated in the near sea of Jeju Island.
The results obtained are as follows ;
1. The buoyancy of the purse seine was 1.26 times to the sinking force.
2. The surplus buoyancy of the purse seine was 26.3 percent to the sinking force and 20.8 percent to the buoyancy.
3. After the purse line in the purse seine was pursed. the buoyancy was 3.39 times to the sinking force.
