Towing tension of the model nets were determined by the load cell(O~20kg, 20DBBP) in front of W〈lrp with the combinations of towing velocity, warp length and the distance between paired boats. Towing tension of the full scale net was determined by the load cell( 0 ~ 6ton) in front of warp with the towing velocity. The results obtained can be summarized as follows; 1. The changing aspect of towing tensions of the model nets A and B varied by the same tendency in the range of O.356-2.019kg and O.352~2.117kg, respectively, depend on the operational factors. Among the factors, the towing velocity was the most influential. The tensions(T) can be expressed as a function of the towing velocity(V) as TmA = 1.57 . V1.86 (unit: kg, mlsec) TmB= 1.58 . V1.90 2. The towing tension of the full scale net was almost coincided with the results obtained by the model experiment. The towing tension(T) can be expressed as a function of the towing veJocity(V) as T=479V1.75(unit: kg, k't)
