🔍 Key Concepts

• Transverse stability and how towing forces affect it • How towline lead and connection height change heeling moments • Relative importance of external force direction versus object dimensions

💭 Think About

• When a tug is tripped, what actually causes the capsizing moment on the tug itself? • Which factors directly change the lever arm (moment arm) between the towing point and the tug’s center of buoyancy? • Which listed item mainly affects the tow, but has the least direct impact on the tug’s stability when tripped?

✅ Before You Answer

• Identify which choices change the heeling moment on the tug (force × vertical or horizontal distance) • Distinguish between factors that affect the tow’s behavior versus the tug’s own stability • Confirm which option has the weakest direct link to the tug’s risk of capsizing when the towline yaws or sets up a beam force
