CP Ships yesterday re-flagged the 3200 teu CP Yucatan to US flag and changed its name to CP Yosemite in recognition of the ship's enrolment in the US government's new Maritime Security Program which comes into effect 1st October 2005 and under which CP Ships is expanding its participation compared with the previous MSP. This week, CP Ships also opened a new office in Washington, D.C. to ensure more efficient management of its US-flag business. CP Yosemite is one of five vessels operating on the TransAtlantic which CP Ships is committing to MSP and which will be named after US national parks. In due course, the remaining four ships will be renamed CP Everglades, CP Denali, CP Shenandoah and CP Yellowstone.
