In late November 2006 all eight of the WPBs were taken out of service due to debilitating problems with their lengthened hulls – all eight hulls were cracking when driven at high speed in heavy seas. These as well as other issues – such as C4ISR problems – drove the program $60 million over budget, triple the original bid for the eight boats converted. The 41 unmodified 110's are now being pressed harder to take up the slack. The eight modified were moved to the United States Coast Guard Yard and moored in Arundel Cove.
