Night Approximation: Proceed in the same way, taking into account the buoy markers:
Coming from the N, sail based on the light from Cabo Prioriño Chico lighthouse (Fl W 5s 36m 23M, visible between 225º and 129.5º), keeping the light on Cabo Prior (Gp Fl(1+2)W 15s 107m 22M) to stern as a point of reference. Located one mile to true S of Cabo Prioriño Chico, set a course of 135º until you no longer see the light from the Tower of Hercules lighthouse (Gp Fl(4)W 20s 106m 23M). At that point, continue sailing on that course based on the green light (Gp D(4)G 11s 15m 5M) at the end of the shelter jetty and the red light (Gp Fl(4)R 11s 11m 3M) on the outer harbour wall. Once at the entrance, head to port to the Marina Sada facilities.
Day aproximación: The wide mouth (3.2 M) of the Ares and Betanzos estuary is located between Punta Coitelada and Punta Seixo Branco, facing the seas and winds from the fourth quadrant. This estuary is divided into two branches: one to the E (Ares estuary) and another to the S-SE (Betanzos estuary). The facilities of Marina Sada are located on the W shore.
Access is very simple, as described below:
Coming from the N, sail to a mile and a half to true S of Cabo Prioriño Chico and set a course of 135º until you no longer see the Tower of Hercules. At that point, it is just 4 miles, turning gradually to starboard, until you reach the entrance to the port. Sada is both a fishing port and a marina. The Marina Sada facilities are located S of the fishing port.
