Sea Bags, designers and manufacturers of handmade items from recycled sails, was named an official partner of the 2016 Atlantic Cup.

The event, presented by 11th Hour Racing, spans 1,000 nautical miles and is the longest offshore race on the Eastern seaboard. The fifth edition of the race will start May 28 in Charleston, South Carolina. Teams will sail to New York for a brief stopover, then compete in the second leg of the race, 350 nautical miles to Portland, home-base for the Sea Bags business. The race ends with two days of inshore racing on Casco Bay.

“We’re so proud to be a part of the Atlantic Cup race,” Beth Shissler, president of Sea Bags said in a press release. “Its mission of being the most environmentally sustainable sailing race in the U.S. aligns perfectly with our own brand, which was founded on the principles of recycling and promoting a more sustainable way of life, in order to preserve our oceans for generations to come.”
