Neutral helm and the hydrodynamic advantage of the Zen 24
Weather helm is the term used to describe a sailboat’s tendency to head up into the weather side when the tiller is a mid-ship. Too much weather helm makes the boat difficult to handle and reduces speed. Most sailboat hull forms have not been considered in reducing the weather helm when the boat is heeled over by the wind.
However, the hull of the Zen 24 has been especially designed so that weather helm is reduced and neutral helm is maintained when the boat is heeling.
The hydrodynamic advantage of the Zen 24 hull form comes from the interaction between the centers of effort and lateral resistance, as the diagrams below show. Because of the unique shape of the hull, the Zen 24 is able to maintain a balanced and neutral helm, even when heeled by the wind. This makes the Zen 24 a very stable and comfortable sailing boat.
