Scott had a work truck with a very large metal tool box in the truck bed. According to the prosecution he placed her body in the box where it was invisible to others. He had a work space and parking space in his rented workshop that was very private. No one would notice if he wheeled a bundle to his work truck. Especially on Christmas Eve.
As for the boat, here is an excerpt:
Using a dramatic series of pictures, prosecutors in Scott
Peterson's double-murder trial tried Wednesday to answer a large question lingering over their case -- how the body of an eight-months pregnant woman could be spirited out of Modesto and dumped into San Francisco Bay without anyone noticing it in a 14-foot fishing boat.
The photos demonstrated that the boat that prosecutors say Peterson used to dispose of his wife's body had ample room to allow a pregnant woman to lie down in various sections of the vessel. And moreover, the pictures showed how a woman's body on the floor of the boat could go virtually unnoticed when viewed from a short distance away.
The pictorial re-enactment, presented to jurors on a large screen by prosecutor
Rick Distaso, featured an eight-months pregnant woman, roughly Laci Peterson's height and weight the day she disappeared, fitting easily inside the boat and a gigantic tool box Peterson kept in the back of his truck. The demonstration marked the first time prosecutors have hinted that Peterson may have used the box to hide his wife's body while transporting it from their Modesto home to a nearby warehouse, where he kept his newly purchased boat.
....SNIPPED....
The re-enactment helped prosecutors diffuse questions raised earlier during Wednesday's testimony about how a body could be kept in a boat at the Berkeley Marina in broad daylight without being noticed.
Several employees of the Berkeley Marina were called by prosecutors to show how quiet the boat dock had been on Christmas Eve, 2004, the day they say Scott Peterson towed the boat carrying his wife's body to the boat launch. Just three people paid the $5 fee to launch a boat between Dec. 23 and Dec. 27, the manager of the marina testified. Two other employees said it was quiet on Dec. 24 because of the holidays.
