【 摘 要 】

The prohibition of the use of fishing gear trawls in Indonesia's fishing territory requires fishermen to make replacements of fishing gear against their boats. The replacement of fishing gear on the boat affects the performance of the boat. This study was conducted to determine the extent to which the replacement can be applied to traditional fishing boat Trawls North Coast of Central Java. The study focused on the ring net and gill net as a catch tool. Based on the results of stability and seakeeping analysis, it can be concluded that the replacement of fishing gear is influenced by the loading factor of the used fishing gear equipment. The vessel with the replacement of the ring net and gill net has a stability below the value of stabilities owned by the traditional trawler of Juwana. For the results of motion analysis, the vessel has met the Tello criteria of acceptance of fish ship characteristics for vessels with full velocity and wave as high as 2m. The vessel has the highest rolling value of 3.31 deg, and slamming probability with the greatest value of 2.10% for speed 6 knots and 180 deg heading on head sea condition.
