Puncture leaks in the lower tubes or bottom...

🔍 Key Concepts

• Inflatable liferaft construction – difference between buoyancy tubes and bottom/floor fabric • Immediate damage control vs. permanent repair – what you do first in an emergency vs. later when conditions allow • SOLAS/USCG liferaft equipment – which item is designed specifically for QUICKLY closing holes in tubes or the bottom under pressure

💭 Think About

• Ask yourself: in rough seas, with the raft already inflated and taking on water, which item could you realistically apply FAST, from inside the raft, to stop air/water loss? • Which option is designed to work on a WET, FLEXING surface under pressure, without needing long curing or drying time? • Which options are more suited for later, more permanent repair when the situation is stable and you have time and space to work carefully?

✅ Before You Answer

• Check which item is normally supplied in the liferaft repair kit specifically for emergency plugging or pinching off leaks in tubes or bottom seams • Consider whether the item requires clean, dry surface and curing time – if so, it is less likely to be the FIRST action in an emergency • Verify which choice is meant to mechanically clamp or close a leak immediately, rather than bond or glue fabric for a long‑term fix
