Practice 1: Work on body mechanics in our drills, focusing on symmetry/teamwork and consistency, and if possible work on rudderless steering, either locking the tiller/rudder or taking it out completely.
Practice 3: Positioning in traffic and mark roundings. Work on far better mark roundings than you have been doing.
