The future of a government program to revive western Canadian shipbuilding remains clouded after investigators released a damning report about cost overruns and bureaucratic bungling. The directors of the B.C. Ferries Corp. resigned after auditors alleged the cost of designing and building a new type of high-speed catamaran ferry had risen from the originally planned $137.9 million to approximately $288.9 million. The report was the latest bad news to buffet the Pacificat fast ferry project, which was launched in 1994 in hopes of developing and building a lightweight passenger ship in British Columbia that could be marketed internationally.
