Most modern icebreakers were super-powerful ships. Li Du had heard of one that had a displacement of 37,000 tons, a power of 7.35×107 watts, a length of 194 meters and a width of 32.2 meters. It would take at least a few dozen crew members to operate a ship like this.
The Blodwen family icebreaker was not a huge ship. The family was rich and well-connected, but could not afford a vessel of such magnitude.
The Hammerhead Shark was just 20 meters long, and its bow shell was made of special steel plates at least 10 centimeters thick. Inside, it was supported by dense steel sections.
In addition to its steel shell, the ship had an extremely powerful engine. It broke the ice by impinging, pushing forward at full speed, and then pushing back to accelerate forward again.
There were crew members on board, but Li Du chose to use his people to sail the ship and let them take care of the maintenance.
