Remember that your gear bag will be stowed under the bus, so pack a smaller bag, filled with things you want while riding the bus. All novice rowers and coxswains MUST wear matching singlets to compete. DO remember your racing shorts. Make certain the shorts fit well-enough that they will NOT get caught in the slide. DON'T forget to bring money for meals.
Many rowers like to collect race t-shirts, so they often sell out fast.
If you want one buy it early in the day. Many times the team has sat in the rain all day. Check with your coach before you throw a coxswain in the water, no matter how big the win is. Don't be surprised by last minute changes in the race order, or your seat or boat assignments. Support your teamates by helping with boats as needed and cheering for other boats.
