Mackay Marine, a division of Mackay Communications, Inc., has expanded its operations with the opening of two new marine-electronics service locations in Corpus Christi, Texas and Panama City, Panama. The addition of these facilities, coupled with the opening of Mackay Rotterdam BV in May 2009, gives customers 15 U.S. locations, two Mackay International service centers, and 90+ international marine service agency affiliations to choose from. Mackay’s goal is to meet the increasing regional and international demand in southeastern Texas and Panama, while establishing itself as a cornerstone of consistent, high quality marine service in these progressive ports.
