From this and other ransom situations, here's a typical accounting for a piracy operation: About 20 percent goes to pay off officials who look the other way. About 50 percent is for expenses and payroll. The leader of an attack makes $10,000 to $20,000 (the average Somali family lives on $500 a year). The initial investor — who put in $250,000 of seed capital — gets 30 percent, sometimes up to $500,000.

Gullestrup's ship and crew were returned safely, although the pirates didn't actually want to get off the ship right away. That's because they were afraid of getting robbed by other pirates on their way back to shore, Gullestrup says, so he gave them a ride north, dropping them closer to home.

Fortunately, he says, he was going that way anyway.
