🔍 Key Concepts

• Ground tackle components used to secure an anchor chain for sea • Difference between parts that guide or cover the chain versus parts that physically grab and hold it • Traditional names for devices that use a grab and turnbuckle arrangement to hold chain under strain

💭 Think About

• Which option refers to something that would actually "grab" the anchor chain and be tightened with a turnbuckle to hold it firmly? • Which terms in the choices are more associated with covers or protective pieces rather than holding devices? • Think about which device is specifically designed as a chain stopper that can take heavy strain when the anchor is secured for sea.

✅ Before You Answer

• Identify which choice is known specifically as a chain stopper with a grab and turnbuckle setup • Eliminate any options that describe covers, deck fittings, or non‑adjustable parts • Confirm that the term you pick is commonly used when securing the anchor chain for sea rather than during normal anchoring only
