CHATHAM, Mass. — Great white sharks are having an unusual effect on Cape Cod this summer, and many a merchant is going to need a bigger wallet.
The sharks being seen in growing numbers are stirring curiosity and a buying frenzy.
Shark T-shirts are everywhere, “Jaws” has been playing in local movie theaters and boats are taking more tourists out to see the huge seal population that keeps the sharks coming. Harbor masters have issued warnings but — unlike the sharks in the movies — the great whites generally are not seen as a threat to swimmers.
Among the entrepreneurs is Justin Labdon, owner of the Cape Cod Beach Chair Company, who started selling “Chatham Whites” T-shirts after customers who were renting paddle boards and kayaks began asking whether it was safe to go to sea.

“I mean, truthfully, we’ve probably grown about 500 percent in terms of the sale of our shark apparel,” he said. The T-shirts, hoodies, hats, belts, dog collars and other accessories bear the iconic, torpedo-shaped image of great whites and sell for between $10 and $45.
Tourists peer through coin-operated binoculars in hopes of catching a glimpse of a shark fin from the beaches of Chatham. The posh resort town is on the elbow of the cape that has a large population of gray seals — whose blubber is the fuel of choice for great white sharks. Local shops sell jewelry, candy, clothes, stuffed animals and beverages with shark motifs.
A study released last month by scientists at the National Oceanic and Atmospheric Administration found the number of great white sharks off the Eastern U.S. and Canada is surging after decades of decline.
Conservation efforts and the greater availability of prey are credited with the reversal.
Shark sightings have climbed from generally fewer than two annually before 2004 to more than 20 in each of the last few years off Cape Cod, where the economy depends heavily on summer tourists. Despite notices urging boaters and swimmers to use caution, the reaction has been nearly the opposite of the panic depicted in “Jaws,” the 1975 film shot mainly on the Massachusetts island of Martha’s Vineyard.
“White sharks are this iconic species in society and it draws amazing amounts of attention,” said Gregory Skomal, a senior marine-fisheries biologist who also leads the Massachusetts Shark Research Program.
Confrontations with people are rare, with only 106 unprovoked white shark attacks — 13 of them fatal — in U.S. waters since 1916, according to data provided by the University of Florida.
Still, officials are wary of the damage that could be done to tourism if one of the predators bites a person.
Brochures have been distributed to raise awareness of sharks and safe practices in the event of a sighting.
“You have to make sure people understand,” Cape Cod Chamber of Commerce CEO Wendy Northcross said, “if they go to the beach and they see a family of seals there, that’s probably not the best place to hang out.”
