🔍 Key Concepts

• Towing gear safety – connections must not come loose if the load suddenly slackens or snatches • Differences between shackles (with pins/bolts) and hooks (open vs. closed, with or without a safety latch) • Why positive locking of a connection is critical in towing operations

💭 Think About

• If the towline suddenly goes slack and then tight again, which option is least likely to jump off, open up, or have the pin/part fall out? • Which of these fittings provides a connection that must be deliberately opened before it can disconnect, instead of just slipping off or having a pin bounce out? • Think about industry best practice on commercial towing vessels: which of these is most commonly recommended for permanent or semi‑permanent tow connections?

✅ Before You Answer

• Eliminate any option with an open throat that can let the towline slip out if it unhooks or twists • Check which fittings have a secure pin or latch that cannot back out or open by itself under vibration and shock loads • Ask: In a heavy-weather tow, which choice gives the most secure, positively locked connection?
