To better meet the needs of the demanding young Optimist sailors, the OneSails mainsails are now available in two different styles: Standard and Advanced.
Standard suits every sailor, while the Advanced is harder to control but allows a greater reward. We do not recommend the Advanced styles to inexperienced sailors since it may result in a far lower performance compared to Standard.
