Abstract
A watercraft kit includes a watercraft and a buoyant removable rear extension optionally connected to a rear of the watercraft. The watercraft includes a hull having a transom and a deck disposed above the hull. The deck is supported by the hull. A propulsion system is operatively connected to an engine for expelling a stream of water rearward of the transom to propel the watercraft. When the removable extension is connected to the rear of the watercraft, the removable rear extension is disposed at least in part rearwardly of the transom. The removable rear extension defines a longitudinal channel. When the removable extension is connected to the rear of the watercraft, the channel receives at least one of at least a portion of the propulsion system, and at least a portion of the stream of water flowing therethrough when the propulsion system is operating to propel the watercraft forwardly.
