TRENDS SEPTEMBER 2018 26 CompositesWorld Can Your Strain Gage or Thermocouple Do This? Small, lightweight fiber optic sensors measure continuous strain and temperature profiles with millimeter resolution.

Visit our website to learn how you can directly measure all the complexities of your composite designs with high-definition fiber optic sensors. Open sea boat racing has proven a perennially fruitful opportunity for boat designers and builders to hone their composites skills, and the recent third running of the Skiff Challenge — a 1,600-mile, nonstop, roughly 48-hour endurance race along the entire coast- line of the US state of Florida, was no exception. Hell's Bay Boatwork's (Titusville, FL, US) owner Chris Peterson got together one evening four years ago over tequila with Heath Daughtry, owner of Florida boat manufacturer Yellowfin Yachts (Bradenton, FL, US), to sketch out on a cocktail napkin (no kidding) the audacious idea for what they conceived of as a friendly competition between builders of fishing skiffs of no more than 5.5m (18 ft) length, with maximum 70 hp outboard motors. That night, they also decided that the chal- lenge would help raise money for the non- profit environmental group Captains for Clean Water (Ft. Myers, FL, US), which advocates for better water quality within the state. This year, 2018, was the third Skiff Challenge, with four teams participating. Starting in Pensacola, participants raced to the southernmost point of Key West, then north, ending at Cabin Bluff Lodge in Woodbine, GA, US. The Hell's Bay entry started with its Biscayne design, a small, 5m (16 ft, 4 inches) open fishing skiff. But instead of the Biscayne's typi- cal cored fiberglass/aramid laminate, Peterson says the Skiff Challenge boat was built with his company's engineered carbon fiber laminate (See CW's previous story about this craft, titled "Super Skinny Water Skiff" | ). The hull, deck and bulkheads were built up from a proprietary hybrid carbon fiber/high-modulus polypropylene (HMPP) fiber woven reinforcement, featuring HMPP fiber from Innegra Technologies (Greenville, SC, US) and manufactured by Vectorply Corp. (Phenix City, AL, US), over a CoreCell (Gurit UK, Newport, Isle of Wight, UK) foam core. The laminate was wet out with Scott Bader Co. Ltd.'s (Northamptonshire, UK, and Stow, OH, US) Crestapol 1260 urethane acrylate resin. Scott Bader Crestomer 1152 adhesive was used to bond the MARINE Hell's Bay skiff redesign repeats win in clean water benefit race Source | Hell's Bay Source | Hell's Bay
