Crossing the Shipping Lanes

AdmiraltySailing-021615-ShipCrossingWhen crossing the shipping lanes, it’s important to take regular bearings on ships as they enter the horizon and even more so when they get closer. This ship had a constant bearing and decreasing range. According to the boat beacon AIS App on my iPhone, this vessel had a CPA of 150 meters. With prudence the watchword, we altered course well to port to pass his stern. Dear Prudence.
