The Global Marine (often abbreviated GloMar) Explorer - the ship built to recover the K-129 - utilized the largest gimbal (a mechanism that swivels in 2 directions) ever built, with bearings over 6 feet diameter, and capable of supporting 20,000 tons.
As in the 1983 movie, the Crazy Ivan maneuver is misrepresented in this film, too. This film shows it as the leading sub suddenly reversing, and "backing into" the trailing sub. "Red October" showed it as the lead sub simply swerving slightly to one side and then stopping, and the trailing sub drifting into it. The actual maneuver is the lead sub swerving 180° and racing back parallel to its original course, then making another 180° turn and continuing either parallel to or exactly along its course. For the trail sub to be undetected, it must shut down and not maneuver until the lead sub passes again. But if the lead sub ends up exactly on its original course, it can unknowingly ram the stationary trail sub.
Though the boat isn't referred to by name, the K-129 incident is mentioned in the "Hunt for Red October" novel; a couple of scenes mention a Golf-class sub that the Soviets lost and which was salvaged off the coast of Hawaii.
Watching this story and how it evolves, it does not sound even close the Tom Clancy based film: The Hunt For Red October. This story begins with a rapid turnaround with an aged diesel-electric submarine, and not a Nuclear submarine. The story more closely fits the Ed Harris film "Phantom". This film's storyline is not even close to the title of: "The Real Hunt For Red October".
