"The pattern is very identifiable. It just sort of fits as a scenario," boat expert Henry Pickersgill told ABCNews.com. "There appears to be a pattern in the vessel's track, speed, longitude and latitude to indicate that it may have stopped briefly for enough time for Mr. Aguiar to have transferred to another vessel."
Police are investigating his disappearance as a missing person case. While some have suggested that the financially and mentally troubled millionaire may have committed suicide, no body has been found. There have also not been any reported sightings of Aguiar.
The 37-page GPS analysis report was released by the U.S. Coast Guard on Thursday. A series of maps show Aguiar's route from the night of his disappearance, including the speed at which he was traveling at all points.
A witness told police the boat was traveling very fast "wave jumping" at some points.
"You can easily say he keeps working northeast towards whatever he's looking for, sees it at the top of the triangle, goes to it, steps off the boat quickly, doesn't even turn the engine off and lets it go," expert Nathan Spaulding told ABCNews.com. "It takes half a second to jump off another boat."
"The top speed of the vessel was approximately 31 miles per hour at 7:35 P.M.," the Fort Lauderdale police wrote in a news release. "At 7:56 P.M., the vessel's GPS data shows an abrupt decrease of speed, slowing down to approximately 0.6 miles per hour, as well as a drastic change in course to head westbound."
From there, the boast drifted southwest with speeds no greater than 3 miles per hour before it washed up on the beach and was eventually towed back to an inlet.
"The track, from where it starts, to the loop before it starts to drift west, looks like someone looking for something," Spaulding told ABCNews.com. "The squiggly areas, where the vessel slows and veers around, is likely [so that someone is able] to talk on the cellphone -- very, very difficult, if not impossible, at high speed."
Something distracted him there," Spaulding said. He theorized that Aguiar may have been on the phone or veering to avoid wind or the night's stormy weather.
After the three bumps, Aguiar picked up speed again until he made a dramatic right turn and then the boat moved diagonally, forming a small triangle, before it began its slow drift back to shore.
Both Spaulding and Pickersgill interpreted this triangle as an unusual maneuver.
