Power of Mumm 30 vs Wauquiez Centurion 45S
Force generated by the sail  proportionates to the sail area.  Larger boat has larger sail and heavier mass. Power/ mass is a parameter to compare power of different boat.
Suppose two boat generate same force/ unit sail area although the sail configuration differ.
Area of Mumm 30 sail are= 27.44+ 19.37 meter2=46.8 m2
mass of Mumm 30=1950 kg A/m=0.024
Area of sail Of Centurion 45s=115 m2
Mass=10500 kg A/m=0.011

Conclusion: Mumm 30 should be faster than Centurion 45S
