1. Titanic Lifeboats: When the RMS Titanic hit an iceberg in 1912 and began to sink, the ship's lifeboats were launched to carry the passengers and crew to safety. However, it was found that there were not enough lifeboats to accommodate everyone on board, which resulted in a great loss of life.
2. Coast Guard Rescue Lifeboat: The US Coast Guard has many rescue lifeboats at its disposal. When receiving a distress call from a vessel in difficulty or people in the water, this type of lifeboat is launched from the shore to perform the rescue operation.
3. Cruise Ship Lifeboats: Modern cruise ships are equipped with advanced lifeboats to secure the safety of passengers and crew in case of emergencies. The lifeboats can carry a large number of people and are equipped with food, water, and other survival gear.
4. Lifeboat Drill on a Cargo Ship: As part of safety protocols, cargo ship crew members often participate in lifeboat drills. This involves lowering the shipboard lifeboat into the water, boarding it, and practicing the process that would occur if the ship had to be abandoned.
5. RNLI Rescue Lifeboats: The UK's Royal National Lifeboat Institution (RNLI) operates a fleet of rescue lifeboats in waters around the UK and Ireland. They are launched from shore when there are reports of swimmers, surfers or vessels in difficulty. The lifeboat crews are volunteer-based and often perform daring rescues in challenging conditions.
