The liferaft contains three red leak stoppers, which instantly plug a hole permitting you to re-inflate the liferaft via the inflation valves. In addition, there is a repair kit containing patch materials, glue and scissors for repairing tears. If the hole is in one of the buoyancy tubes the liferaft will still be functional. Every single tube can support the weight the liferaft is approved for. So even with one buoyancy tube deflated, the liferaft will continue to support the occupants.
