On a hot, sunny Saturday last August, a huge line of hundreds of boats filled a bay of Lake St. Clair near Detroit for the annual daylong floating party known as the Raft-Off.
The revelers included thousands of women in bikinis and men in swim trunks and flip-flops. There was also a guy from Minnesota, sweating in a navy blazer, gray trousers, dress shirt, necktie and clipboard. He was one of the few people not in or on the water and not drinking a beer. Instead, he was counting.
That was Mike Marcotte, the man from Guinness.
More precisely, Marcotte is a Guinness World Records adjudicator, one of the judges that the record-keeping and publishing company hires, trains and dispatches around the world to deem whether something is the world's biggest, longest, heaviest, tallest or some other measurable superlative.
Marcotte was in Michigan to judge the attempt on the world record for the "largest boat tie-up," last set when 1,651 boats were tied together in a single unit on a lake in Kentucky in 2010.
The 32-year-old Minneapolis resident also was in northeast Texas when hundreds of motorcyclists tried to set the world record for largest parade of Harley-Davidsons. In San Diego when an attempt was made on the record for most waste paper shredded in eight hours. And in Canada, watching to see if the world's largest sugar cube structure would be built.
Marcotte is a world-record decider, the guy on the spot with the job of declaring to hundreds of participants or dedicated volunteers that they just claimed their 15 minutes of fame — or that their hopes of Guinness glory fell short.
"There's always something new and fun," said Marcotte of his job as the arbiter of offbeat pinnacles of human achievement. "I get to see the biggest of the big, and the smallest of the small."
