Click inside to see what the fan theories are about just how Gibbs gets the boats out of his basement on NCIS… Over the course of the series, Gibbs has made a total of five boats. The question was first asked in the first season by Abby Scuito, who once instructed Tim McGee to search for cracks in the floor and walls to see if there was a way that walls could be lifted and the boats taken out that way. However, he didn’t seem to find any. Abby also had a theory that Gibbs disassembles it and then resembles it again, as well.
