🔍 Key Concepts

• SOLAS requirements for line throwing appliances on seagoing vessels • Minimum number of projectiles/rockets and how many must be buoyant • Purpose of a buoyant line-carrying rocket versus a non-buoyant one

💭 Think About

• Think about why some rockets must be buoyant. In what situation would a floating line be essential? • Consider whether regulations usually require redundancy (spares) for critical survival equipment—would two, three, four, or five be more consistent? • Ask yourself: is there typically more than one buoyant rocket required, or just a portion of the total set?

✅ Before You Answer

• Check the exact SOLAS specification for line throwing appliances and count how many projectiles/rockets are required in total • Verify how many of those projectiles must be buoyant line-carrying rockets • Confirm whether the regulation talks about "one of which" or "two of which" must be buoyant, and match that wording to the choices
