Professional BoatBuider 151 coverOn the cover: Building high-quality tooling to tight specs for some of the best-known manufacturers of composite boats has been the core business for Florida-based Marine Concepts since 1976. As boatbuilding technologies have evolved, so have the demands on this mold builder, which has expanded facilities and hired and trained staff to meet the changing needs of clients. Here, an infused Hinckley T34 (10.4m) hull just sprung from a robustly built Marine Concepts mold hangs between its halves. Story on page 68.
