Professional BoatBuilder cover 153On the cover: Composites technician Mike Griffin marks the perimeter for the next layer of prepreg carbon fiber reinforcement to be applied where Comanche’s canting keel will attach to the bottom of the 100′ (30.5m) VPLP-designed sloop. Hodgdon Yachts’ first significant prepreg build, this ambitious 2014 project required reconfiguring the shop and infrastructure as well as retraining a crew already skilled in other advanced composite construction methods.
