Abstract
Development of conventional fish hold design to live fish hold design may provide an alternative solution to keep
costs of preservation of fish catches down. Live fish hold systems left the water in the hold with sea water to
circulate around by giving a hole at the base of the hatch. Rembang traditional fishing vessel has the basic
characteristics of a flat bottom with a long form of the stern board and has a habit of leaning on the edge of the
ocean with a sloping surface.
The research was carried out on several models of variations in the number of holes and diameter of holes.
Water in the live fish hold with ship stationary state will have the same height with a draught of ship, but as
increases of speed of ship then the height of water in the hold will decrease.
Based on the analysis and calculation of Computational Fluid Dynamics method results obtained show that the
optimum velocity of each model reaches 7 knots. Models with a variation of amount 4 holes with 2 inch diameter
hole has an average altitude of the highest water level of 2.16 m at a speed of 7 knots.
