What happened: SailGP crews and their coaches have developed encrypted language to communicate during races. That system took on added importance during a recent storm-ridden weekend, when weather made the course nearly invisible and on-boat technology malfunctioned.

Why it matters: The communication setup shows how teams prepare for races when normal sightlines and onboard systems break down. It also underlines the role of coaches in helping crews adjust quickly when rough conditions disrupt standard race management.

What to watch: Future heavy-weather weekends will show how much teams continue leaning on coded calls when onboard systems fail.
