The San Juan Sailing Foundation is offering a four-week racing series that starts Thursday, 5:30 p.m. Meet at the Net Shed at Jackson’s Beach.

Right after sailing team practice and before the sun goes down, the foundation will have the course set and the boats rigged.

For $60, you get four weeks of sailing in the foundation’s Vanguard 15s and a family membership in the San Juan Sailing Foundation. Each individual week will cost $20.
