Recon in the 37th America's Cup is governed by a new set of rules. Each team is assigned a two-person Recon Unit to follow their every on-water move and then share the footage with their competitors, but it's not that simple. The cameras are supplied and the same for all Recon Units. Drones are not allowed, and they can't get that close, + following a boat at 45 knots isn't easy to begin with.
