What are the winds and waves like on the Yangtze?

No lie. Seriously. I have been on boats similar to that of this. These boats are challenged if the wind and waves are significant. If the captain and crew are not schooled in real navigation problems they won't know how to handle a changing condition of the water. 

Navigating a river is far different than navigating the seas. A captain and crew with experience in sea navigation is more desirable than not. The Yangtze is not a small river. The larger the surface area of any body of water the greater the potential for adverse effects when navigating it. The larger surface area catches more wind and creates larger and more frequent waves, ie: Pacific vs Atlantic Oceans. 

There is absolutely no doubt as the air masses heat there is higher velocity of winds due to the lack of movement, except Coriolis. The winds are reacting to the heat and increasing in velocity while in stagnant global movement. Why the heat matters? The air mass expands and provides for larger surface area for the increased velocity. 

I hope this isn't something like drunkenness. That profoundly shows a culture problem within the navigation community. China is capable of surmounting the challenge to solve this problem regardless it's cause.

JIANLI, Hubei Province, June 2 (Xinhua) -- Twelve people (click here) have been rescued so far and another five confirmed dead after a cruise ship carrying 458 people, most of whom were elderly, sank in China's Yangtze River overnight.
The Eastern Star, which left the eastern Chinese city of Nanjing at 1:15 p.m. Thursday bound for Chongqing Municipality on the upper reaches of the river, sank "within one or two minutes" of being caught in freak weather in Jianli, Hubei Province, according to the ship's captain and chief engineer who survived the incident.
The sinking could be the worst in China for decades. The water is 15 meters deep where the four-storey ship sank at around 9:30 p.m. Monday in the Jianli section of the Yangtze, according to the river navigation administration....
