Abstract: A manually presettable speed, continuously indicating, computed distance navigational computer for vessels comprising an electrical preset speed display meter, an electromechanical digital computed mileage indicator, a pulse generator for operating the mileage indicator to provide a continuous digital display of computed distance travelled at a preset rate with the passage of time and a manually adjustable electrical resistor common to the pulse generator and meter for establishing the pulse generator frequency and operating the meter to display the estimated preset speed needed to product the computed distance travelled with time at said preset speed for setting a desired speed into the computer. Actual speed through the water may also be displayed on the meter.
