Sailing and weather are intrinsically linked. Experienced Mac sailors understand that developing a pre-race weather forecast and monitoring its evolution on the racecourse is an important strategic and safety aspect of participating in the Race. Misjudging the wind forecast can quickly send you to the back of your fleet, while failing to properly assess the risk for severe weather can unnecessarily jeopardize the safety of the crew.
