Katja is our model of an elegant four-seater sports boat with inboard motor, and it has turned out to be hugely successful. The model essentially consists of seven plastic parts. The deck and cabin are moulded in one piece in clear plastic, which eliminates the complex task of cutting out and installing the glazing panels. The Katja can be operated free-running or with radio control. In its simplest form the rudder is set for a fixed radius of turn. Once equipped with a radio control system the Katja is remarkably manoeuvrable, and its power system gives it a very lively performance. We recommend the romarin by krick Katja as an ideal fun model for the beginner.
