.......... I recall seeing the boat being used in BC to Vancouver Island before it was sold.
"The Cat was purchased by Fujian Cross Strait Ferry. The vessel has been renamed Hai Xia Hao and now operates between Taichung and Pingtan Island.[2]"
No.....the Cat you mention above never operated in BC to Vancouver Island.
And to clarify another point......there is no bus between Yarmouth and Digby. Acadian Lines hasn't serviced this route in several years.
Trius Bus Lines provides a scheduled service between Yarmouth and Halifax via the South Shore (Shelburne, Liverpool, Bridgewater etc)
