One of the last projects that Apple co-founder Steve Jobs worked on before his death was commissioning the minimalist designer Philippe Starck to build his family the yacht of their dreams. Now, Starck is alleging that Jobs never fully paid him for the task.

The yacht, which was finally completed in late October and christened Venus, has been impounded in Amsterdam as Starck contends he was only paid €6 million out of the €9 million fee he was owed by the Jobs family — or a difference of about $4 million.

"The project has been going since 2007 and there had been a lot of detailed talk between Jobs and Starck," a lawyer representing Starck's company told Reuters. "These guys trusted each other, so there wasn't a very detailed contract."

The entire cost of building the yacht was reportedly more than €100 million, or about $130 million. The yacht itself is between 230 and 260 feet long.

Details of Jobs' plans for the yacht first surfaced in Walter Isaacson's biography of him, which was released shortly after Jobs passed away last year. "I know that it’s possible I will die and leave Laurene with a half-built boat," Jobs told Isaacson. "But I have to keep going on it. If I don’t, it’s an admission that I’m about to die."
