It's not that silly when you work it out. You have a ship holding 2-3 million barrels of oil and a 20-40 crew. It looks like the market price of light sweet crude varies by as much as $1 per barrel per day. Which means a difference of 2-3 million dollars if you come to port today instead of yesterday.

Not silly in that sense. Silly in the pragmatic sense that expensive ships spend considerable amounts of time doing nothing...
