What name was given to the boat built by Robinson and Fritz in the classic The Swiss Family Robinson?

From the text:

Fritz next ornamented the top of the mast with a little red streamer. He then gave our boat the name of the Deliverance, and requested it might henceforward [pg 044]be called the little vessel. To complete its equipment, I contrived a rudder, so that I could direct the boat from either end.
