Abstract
In Designing a Small Ship, the Design of the Trim for Sailing has a great influence on the Stability of the Ship as well as Resistance. The Center of Gravity of a Ship is mostly determined during Initial Design. This Study confirms the Effect of Trim on changes in Vertical Center of Gravity by Numerical Analysis for a Small Catamaran. The Results were examined in a Model test. However, No Model tests were conducted while varying the changes in Vertical Center of Gravity. Nonetheless, Investigation was completed for the Purpose of presenting Vertical Center of Gravity results according to plans for the Trim during Initial Design of a Small Ship. In order to verify the Results of Numerical Analysis, a Comparison with Experimental results was carried out. Alternation of Trim angle and Resistance performance according to changes in the Center of Gravity were studied.
