As the Navy was either tied up to the dock or playing outside, the sail away from San Diego was un-eventful and so it continued for the remainder of the evening and night. Until the Mexican border we sailed with a max. speed of 15 knots, to comply with the Clean Air Act of California. This is not compulsory for us but all the ships are requested to do so and it is the HAL standard that we comply with any voluntary environmental initiative where safely possible. What is compulsory is that we run the ships on Marine Gas Oil (MGO) instead of on HFO (Heavy fuel Oil) in order to keep the emissions down along the Californian coast. As it well-known, Los Angeles had to deal with smog quite often in the past and the local authorities have been quite active with measures to reduce it. One of those measures is that ships sailing along the coastal area here, or going in and out of port run on MGO, as slower speeds give less emissions. Which makes sense, because when you arrive or depart from a port you are not going that fast, do not have maximum load on the engines and thus there is not always optimum combustion. Once past the Mexican border we set an average speed of 17.5 knots with an engine configuration that enabled us to sail with maximum efficiency and thus the least amount of emissions possible.
