Sailracer has issued their updated PYs following their analysis of the early stages of the SailJuice Winter Series as well as some returns.
The three numbers below are ...
PY; 2014-15 SailJuice; Latest released for 2015 Great Lakes events such as the Roadford Rocket
Aero 5 1105 , 1080 , 1122
Aero 7 1065 , 1040 , 1061
Aero 9 1025 , 1015 , 1031
The D-Zero is also 1031 in their latest suggesting early data suggests they are the same speed.
Food for thought.
Based on Sunday's Grafham GP, being overpowered is a slow way to go. As the wind speed increased Pete T in his Aero 5 rig got closer to me in my 7, Jamie was overpowered in his 9 rig.
