The surveyor was extremely meticulous in collecting data during the sea trial.
After leaving the Zhoushan Archipelago, the yacht continued northward along the predetermined course.
At this time, Li Younan and his crew had just passed Shengsi County, the northernmost part of the Zhoushan Archipelago.
Their route was to travel southeast from Hengsha Island, then head directly north without passing Hengsha Island again.
After passing through Yushan Island, they would bypass Hengsha directly, arriving at the mouth of the Yangtze River before proceeding straight towards Qingdao.
The upcoming route was a critical transition point as Li Younan's yacht left the Zhoushan Archipelago and sailed into open waters.
The channel ahead was a famous fishing area, and December was the peak fishing season. The currents were swift, reaching speeds of three to four knots during high tide, with complex flow patterns.
The surveyor began to collect and verify important data on the yacht.
