This is the most recent version. This model has been discontinued by Proboat but is the best full sized RC boat you could get a few years ago. The hull is fiberglass and the boat from the bottom of the keel to the top of the mast is 78 or so. This has been collecting dust in my garage for too long. It is the last of my RC collection looking for a new home. Runs on AA batteries in the remote and in the boat and will run forever on them.
