About CosASail.org
Welcome to the Central Oklahoma Sailing Association (COSA). We are an enthusiastic and social group of sailors at Lake Hefner in Oklahoma City. Our members enjoy meeting to eat, talk, and of course, sail. We schedule social events such as family cookouts and evening cruises, special contests and programs, and a series of roughly 20 club races open to all members whether experienced or novice. Feel free to come out and share in this rewarding outdoor lifestyle.
