The estimation of the loading and the center of gravity height on a small working vessel was perfomed using the physical properties of kelp (Laminaria japonica ARESCHOUG). According to the results of the relative sensitivity analysis for each parameter, the loading and the center of gravity height can be described by the local height and area of a cargo by using the physical properties of kelp parametrically. To determine the loading at a kelp cultivating site, the initial bulk density of kelp and the area and maximum height of the cargo have to be considered. To estimate the center of gravity height, the maximum height of the cargo has to be considered.
