abstract:A second mate (2/M) or second officer is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competency, which is issued by the administration. The second mate is the third in command (or on some ocean liners fourth) and a watchkeeping officer, customarily the ship's navigator.
Hamilton was eight seconds in front by the time of the second pit-stop period, after which Raikkonen slowed and allowed his team-mate to take second place at the end of the back on lap 49.
