John Selleck is the new general manager of the new American President Lines operation in Guam. But this is not the first time around the block here for either Selleck or his shipping company. APL operated on Guam for many years before Matson bought it out 20 years ago. Selleck’s ties to the island began in the early 1990s, when he was hired as a consultant by the government of Guam to help in a dispute with shipping carriers over rates. Ironically, one of the companies involved in the case before the Federal Maritime Commission was APL.
