A captain has to take responsibility for the profitable operation of the tug

Arnold: “Mob and Demob is where a tugboat uses most fuel during the day. Sailing speed during that time is one of the most important factors driving consumption. A captain has to take responsibility for the profitable operation of the tug; he/she sails fast if required to be on time, but reduces speed and thereby fuel consumption if you can. I think it makes no sense to sail full speed and then lie still at the tow for 20 min because you’re early for the job, or stay in bed for 10 extra minutes and then having to rush the tug to the job.”
