Abstract: Fishing boat in Indonesia generally use wood materials. In its development, PVC pipe alternative material can be used as hull. Ship accidents in Indonesia are much due to the turning of boats (capsizing) related to the rolling movements of boats. This research aims to know the fish liner made of PVC pipes with a variation of the hull shape has floodable length that corresponds to the standard SOLAS (Safety of Life at Sea) and know the change in the rolling movement of boats caused by The addition of passive U tube tanks. The method used in this research is by making modeling with variations of 3 hull shapes and making 3 models of passive tanks of different width size channels to be used in the study. Based on the results of the analysis of shipping software and CFDS for floodable lengths have the results indicating the floodable length of the boats of different variations of the stomach shape have different curved graphs and have fulfilled the rules of SOLAS. The rolling result obtained by the ship with the addition of passive tank. The results of the research showed that boats using passive tanks were able to dampen rolling movements. In model A was able to dampen by 4.40%, model B was able to dampen by 8.10% , and model C could dampen the rolling motion by 15.28%. The wide influence of passive tank is very influential on decreasing in the value of RMS Roll of PVC fish with flat hull.
