Using the above for half load (9210lbs) = 73.8mph (average) and light load (7954lbs) = 79.5mph (end of race)
The weights are based on a 37ft al.alloy OP1 with 1050hp.
Dry Martini (36ft ciggy) averaged 83.2 mph in one race with 1200hp,and if you used the above as a guide that could give 89.0mph in light condition,so 88.0mph with 1050hp I would have thought must have been absolutely balls out.
BTW 1979 Free Spirit - G.Leiber (36ft ciggy),what was that boat`s history I wonder.

Interesting this formula to seek the speed but I believe that we are in the bush like with the dimensions of the boats. The power officially communicated is often fluctuating and tied up to the intentions of whom uses them or who produces them.More horses with donkeys and zebras for the one who wants to impress. Less power for the one that doesn't have interest to that they are more.
Graham about the Free Spirit I have always had the suspicion that it was in reality a 35.'
