Cruise ships and blue whales, while they may be two of the largest creatures in the sea, are not easily comparable. Cruise ships are man-made vessels that can be up to 360 meters long and weigh between 60,000 and 100,000 tons.
They are powered by large diesel or gas turbine engines, with multiple decks that contain amenities such as restaurants, swimming pools, bars, theaters and more. Blue whales are the largest animals on Earth and can reach lengths of up to 30 meters and weigh up to 190 tons. They are powered by their own strength and have no need for amenities.
Cruise ships have the advantage when it comes to size but blue whales have an edge when it comes to speed. Cruise ships typically cruise at speeds of around 20 knots (23 mph) while blue whales can swim at speeds of up to 28 knots (32 mph).
This means that blue whales can cover a lot more ground in a given amount of time than cruise ships.
When it comes to longevity, both cruise ships and blue whales have impressive lifespans. Cruise ships often last for decades with proper maintenance while blue whales can live up to 80 years in the wild.
Overall, it is difficult to directly compare cruise ships and blue whales because they serve different purposes in the ocean. While cruise ships are larger in size than blue whales, they cannot travel as fast or live as long.
Conclusion: It is clear that while cruise ships may be bigger than blue whales, they cannot match them in terms of speed or longevity. Therefore, it is safe to say that there is no definitive answer when it comes to which creature is bigger.
