Congrats.
You know you may underestimate white sail reaching capability. Bethwaite records 49ers as being faster white sail reaching than with the kite up, and it wouldn't surprise me if Cherubs are the same because the fore and aft sails are very efficient and low drag and that big baggy thing that gets you down w/l courses isn't.
A course with lots of fully powered up white sail reaching may well suit Cherubs because you'll be planing properly, not stuck in the top end of semi displacement like most classes.
Of course the fly in the ointment is managing to maintain the required level of sailing talent to keep the boat upright and physical effort to be able to drive the boat flat out all the way. Clearly you achieved that, so congratulations again.
