Abstract
Estimating ship roll motion precisely is still an unsolved problem today. The most common and easiest approach to estimate roll damping are decay tests. The performance of roll decays theoretically is simple, but in practice many parameters affect the results obtained from them. In particular, mechanical devices used to initially heel the ship may have a significant influence on the decaying curves, and thus the associated roll damping coefficients. In the present paper, three mechanical devices were used to carry out roll decays on a trawler fishing vessel. Obtained nonlinear damping and equivalent linear damping coefficients are compared.
