What sort of speeds did they hit?
"Alex Cousin 34.5kts 2sec
Thomas Goyard 36.4kts 2sec
Lucas Guiraud 36.45kts 2sec
Nico Goyard 38.7kts 2sec
The full Phantom team used the IRIS 78 board (Nico and Tom had a pre-series X mk2), the IRIS R foil (R350 mk2 wing, 100 EVO fuselage, R175 stabilizer) and the R mk2 4.5 wing"
