Quantum are the only Factory team in the event, all others are a mix of private funding and some sponsorship, then again you could argue that it's DeVos money and Doug as well as Dalton have, and do helm the boat at certain events, so not a true All Pro team, this is beside the point.
Quantum Sails sponsors their boat and supplies to Onda, Platoon and last year Gladiator. Through this, Q provide tuning tips and on the water line ups between those clients and a flow of information and design evolution. Platoon were crowned World Champions, beating Q in Scarlino last year, Gladiator were tied for 1st, but lost out to Azzurra in the last event in Mahon on countback. So Q isn't unbeatable either by their clients, or as witnessed by their bow number, other teams.
North supply the rest of the fleet and also provide a similar support structure with their sail designers being on site during events, going between the teams and offering speed debriefs. Most teams have a dedicated coach on the water taking photos of boats and set ups to provide a day by day debrief internally.
North Sails as well as Southern Spars (read North Group) are Technical Partners to the Super Series, as well as Quantum Sails.
