The first things to arrive of course will be the all the lost ships.
"A U.S. Coast Guard cutter unleashed cannon fire on the abandoned 164-foot Ryou-Un Maru on Thursday, ending a journey that began when last year's tsunami dislodged it and set it adrift across the Pacific Ocean."
It may look like a rusty bucket to some, but that ship could easily be worth a million dollars if towable and/or salvageable.
On the off chance there are some larger or higher quality (nickel hulled) ships, salvage rights will be tested for sure. There might be a few $10 million ships floating our way.
