🔍 Key Concepts

• Tripping (girting) definition – how a tug can be capsized by the towline when the line leads abeam or forward of the beam • Differences between harbor/coastal towing and ocean (deep‑sea) towing – especially maneuvering frequency and towline length • Whether water depth or towline forces and direction are the real factors in tripping risk

💭 Think About

• Think about what physically causes a tug to trip: is it the depth of water, the length of the towline, or the direction and magnitude of the forces on the tug? • Ask yourself if the forces that can capsize a tug (towline pulling it sideways or forward of the beam) can exist only in shallow water, or also in deep water (open ocean). • Consider whether a long towing hawser automatically prevents the towline from ever coming abeam or ahead of the beam of the tug.

✅ Before You Answer

• Be clear on the true cause of tripping/girting – towline lead and overturning moment on the tug, not just environment. • Check whether any option claims that deep water or long hawsers remove the danger – decide if that matches your understanding of towing physics. • Eliminate any choice that bases safety solely on water depth rather than on the tug–tow line angle and forces.

Is tripping limited to harbor and coastal towing?

No. Forces tending to capsize a tug are as dangerous on the high seas as they are in harbor and coastal work.

Yes. Because of increased water depths, forces required to capsize a tug are not usually found in ocean towing.

No. Tripping is common in ocean towing because of more frequent maneuvering.

Yes. The long towing hawser used in ocean towing eliminates the danger of tripping.
