This was recently posted in an other thread: where do big companies list ships for sale.
See: nautisnp.com. Search under under containerships geared.
Transatlantic is listed for $2.5 million.
I'm certainly no expert on ship prices, but compared to the prices of other listed ships, and given that the last info posted on gcaptain was that she was in Long Beach being detained by the USCG for innumerable deficiencies, that sounds to me like a ridiculously high price for such an old foreign built ship.
