How did Special Agent Gibbs get his boat out of his basement?

Fact: Gibbs does not mislead or lie to children. Fact: In Season 3 Episode 7 Honor Code Gibbs explains to a 6 year old boy named Zach, that he could tear out the outer wall of the half-basement, build a ramp and pull the boat out. As the basement of his house is only half underground, evidenced by Windows above them, only part of the wall would need to be removed and a simple wooden ramp could be used to move the boat upward. This explanation is further in keeping with his explanation to Agent McGee, that he would remove a boat by "breaking the bottle". For a carpenter of Gibbs' skill, this would not be a hard feat.
