KIS 4.0

We designed KIS dinghies in order to meet a very practical need of amateur boatbuilders. Since they often find themselves in trouble in building masts, sails and rig of their boats and are likely to spend in these items much more than what they paid for the materials to build the hull , we thought to design four boats, simple and easy to build, suitable to be rigged with spars and sails of four very popular dinghies : Laser , Flying Junior and 470. This allows the builder to easily find equipment and accessories for his boat, either buying them new from dealers either finding them on the second hand market.

The KIS 4.0 compatible with the rig of the Flying Junior ( FJ ). FJ was designed in 1955 by Uilke Van Essen as a smaller and easier version of the demanding Flying Dutchman . In the sixties and seventies of the last century FJ has been the most popular double dinghy for sailing schools and for people who wanted to start racing activity, role that later has rather been taken by the 420 . Compared to the 420 the FJ is easier to sail, which makes it a very versatile dinghy, suitable for racing and for family sailing. The KIS 4.0 has a flat bottom hull with two chines, which makes the hull very similar to a round hull and gives to it good planning qualities. The deck and cockpit layout is that of the classic version of the FJ, built in Italy by Alpa in the sixties, which seems to us the best and most practical one: there is a foredeck from the bow to the mast step, under which there is space for a large locker.
