Summer Sailstice - founded by California sailor John Arndt in 2001 and billed as the world's largest sailing celebration - returns the weekend of June 19-20.
In the spirit of the event, sailors around the globe are invited to start the summer season by hoisting their sails for a ceremonial sail in their home waters during the summer solstice weekend.
The goal is to get as many sailboats in as many time zones as possible on the water during a 24-hour period.
As the sun rises and sails are hoisted around the world, all are encouraged to take a picture and sound a blast as the sun crosses their local solar noon. Last year, almost 4,000 sailboats and 15,000 sailors celebrated the Summer Sailstice.
To participate in this year's event, sailors can sign up for free at www.summersailstice.com.
