🔍 Key Concepts

• Frapping lines are used to control a lifeboat’s movement alongside the ship during lowering and loading • In heavy seas, the boat tends to surge (fore-and-aft) and swing (in-and-out/athwartship) against the ship’s side • Proper rigging minimizes damage to the boat and injury to people boarding

💭 Think About

• Picture how a lifeboat moves alongside a rolling ship in heavy seas—what directions of motion do you most need to control? • Which rigging arrangement would best keep the boat close to the ship’s side and prevent it from surging ahead/astern or banging in and out? • Look at each option and ask: does this setup give positive control over all the dangerous directions of movement, or just some of them?

✅ Before You Answer

• Confirm your understanding of what fore-and-aft and athwartship mean in terms of motion relative to the ship • Check which choices provide control from both ends of the boat versus only forward or only aft • Verify which option actually addresses more than one plane of motion (not just one direction of control) in heavy seas

When lowering lifeboats in heavy seas, a good practice is to rig frapping lines which way?

Rig with fore and aft as well as a thwartship lead

Rig only on the forward falls

Rig only on the after falls

Rig the falls from the main deck of the vessel
