Sail Jet Propulsion

enhanced maneuverability

Sailboats are steered by a rudder and require a flow of water over it to effect a change in direction. At the hull speed (cruising displacement sailboats average 6-8 knots) a small change in rudder direction affects a rapid change in boat direction. However, when docking the boat at slow speed, the rudder is less responsive and rapid acceleration in either forward or reverse is required to change direction. This requires a skillful operator and can have poor results when wind and currents are also affecting the steerage. Unlike propellers, water jet thrusters can direct their water flow radially in addition to forward and reverse. This capability enhances the maneuverability of the sailboat at slow speed making docking an easier and safer activity. (Patent Pending)
