Increased ocean allowance. When a vessel operates exclusively between ports in North and/or South America and within the area limited to 30° W longitude, 60° S latitude and 170° W longitude, the basic wages are paid at 125% for the time the vessel operates within the aforementioned area. The increased allowance is paid starting from the day when the vessel is within the abovementioned area and begins to load for another port inside the area to the day the vessel departs the last port within the area.
