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

  1. This is a very simplified reasoning and the conclusion is false. Very important for the boat’s speed is length of waterline (LWL) – the longer it is, the faster the boat is. Another very important thing is the status of the sea surface – bigger boat can cope with the waves much better than smaller boat. The only advantage of the smaller boat vs. bigger boat is that she can surf earlier in downwind sailing.
    This is simplified too, but in most conditions and with the same level of wordorobe and crew, Centurion 45S should be faster tha Mumm 30.
