Numerical Study about Effects of Stern Skeg on Course Stability

摘要

Course stability is one of important factors of ship maneouvrability.rnRecently, in order to improve of ship propulsion performance, the buttockrnflow hull form has often been used. However it is well known thatrnships with buttock flow stern tend to have inferior course stability. Sornin order to improve course stability, ships with buttock flow stern arernoften equipped with stern skeg. Effects of stern skeg on course stabilityrnare not always clear, it still worth considering.rnWe studied about interaction between hull and stern skeg such as ratiornof additional lateral force induced by stern skeg and the distance betweenrnthe center of gravity of ship and the center of additional lateralrnforce.
