Ship Maneuverability

Ship Maneuverability：Ship Maneuverability、Turning Capability Standards、IMO Standards for Ship Maneuverability

Ship Maneuverability

• Ship Maneuverability
  • Inherent dynamic stability,also called straight line stability
  • Course-keeping ability,also called directional stability
  • Initial turning/course-changing ability
  • Yaw checking ability
  • Turning ability
  • Stopping ability
• Turning Capability Standards
  • Turning test
    • The turning test is performed to evaluate the turning ability
  • Zig-zag test
    • The zig-zag test is performed to evaluate the initial turning,the yaw-checking and the course-keeping abilities
  • Stopping test
    • The stopping test is performed to evaluate the stopping ability
  • Spiral test
    • There are two kinds of spiral test and the reverse spiral test,which are performed to evaluate the ship dynamic stability and course-keeping ability
