It's time again for the Antigua Barbuda Hamptons Challenge Regatta, an amateur sailing race in Noyac Bay, and a day of Caribbean-themed fun in Sag Harbor, planned for Saturday.

The Hamptons Dog Show, hosted by the East Hampton Lions Club at the American Legion Hall in Amagansett, returns Saturday for its fifth year to raise money for the Guide Dog Foundation of Long Island.

Lighthouse Weekend will be celebrated at the Montauk Lighthouse on Saturday and Sunday from 10:30 a.m. to 6 p.m., with re-enactors from the Third New York Regiment and the Kings of the Coast Pirates helping to bring the past to life.

“It’s been a great season thus far,” Harvey Bennett, former owner of the Tackle Shop in Amagansett, said of blue-claw crabs. “They are large and plentiful. More people need to take advantage of it. Blue-claws are the best to eat.”
