MARAD financed their construction by a Florida yard (to subsidize the shipyard) for Brazilian owners. Brazilian owners went under and MARAD repossessed them.
As I recall, MARAD paid Crowley to tow them back from Brazil one at a time with the big Ocean class tugs. Ridiculous waste of money, they should have towed all of them at once in a triple tandem.
Marad probably paid Crowley more to tow them back to Florida, than they got from HOS for the boats.
