Pity the poor mechanic

After a shout or an exercise, the lifeboat is washed down by all present then, while the rest of the crew get off the boat, the mechanic must complete the remainder of his tasks...refuelling the boat, re-stocking any stores used, re-ordering anything which requires it, fixing anything which has been broken before being able to finish up. Sometimes this takes 10 minutes, sometimes several hours...by which time most of the rest of the crew have disappeared.
