... force and side forces at static (fixed) hull yaw angles of 0, 1, and 3 degrees at four ship speeds, ranging from 20 to 36 knots. Side force and yaw moment data were analyzed in terms of the standard linear sway force and yaw moment derivative coefficients Y'v and N'v. These play a role in ship controls...
