Weather update: As trimmer, I help choose the sails for the day. For this reason, weather forecasts are vital to my prerace routine. Plus, I can be better organized. I try not to rely on a single weather prediction. Even if the team has paid for a professional weather forecast, be open to other sources as well. Use the Internet, the race committee, a local sailor or, in the case of bigger boats, your own navigator, who will often have a "hedge" that differs from the professional forecast.
Sail list: Once I have an idea about the weather, I make our sail list: mainsail, jibs and kites. We always refer to them by the code names written on the sail or sail bag. We cannot afford any confusion here, as it's a breach of class rules to carry sails that are not permitted (unbuttoned sails, for example) or to race without sails that must be on board (the heavy-weather jib, for example). In bigger programs, the list is emailed to the entire team before we arrive at the boat so everyone is on the same page with the "sail shuffle."
