Some asthmatics let the condition slow them down, but sailor and educator Rich Wilson has never let it get in his way. At noon yesterday, Mr Wilson (above), of Massachusetts, and crewman Rich du Moulin, of New York, left the Royal Hong Kong Yacht Club onboard Great American II, a 53-foot trimaran (left). They hope to break a 154-year-old Hong Kong to New York sailing record of 74 days and 14 hours set by a clipper during the tea trade. But the voyage's purpose is education. Through a Web site founded by Mr Wilson, sitesalive.com, students can follow the journey and learn how science is applied at sea. 'For me, there is also a risk in the ocean as anxiety is one of the triggers of asthma,' said the 52-year-old former high school maths teacher who has worked with asthma groups during previous voyages.
