Like their competitors in the recreational boating industry, C&C Fiberglass Components Inc. struggled through the recession. “In October 2008 my phones just stopped ringing,” owner Jose C. Daponte said. “We went from 38 employees to 12. For us it lasted almost a year.” But the Bristol company survived in better shape than most, with staffing now back up to 30. A 23-foot, in-shore racing sailboat built by C&C dubbed the J/70, won this year’s Sailing World magazine best-boat distinction.
