Hope I don't offend Jim with this, no malice intended, but you are comparing Jim's time with the best F18HT in the US. Looking at the specific times for the Aust Nats in 2003 the top boats boat were beating the middle to tail end of the fleet by over 6 minutes in every race over an hour. I think if you deducted that from Jim's times in the US and then that would be interesting. Jim has some good races in AUs and did not sail with a regular crew and I think was heavy at the Nats but I am sure he would be very happy to place in the top 10 at the Australia Nats if it was all going well and he sailed with a regular crew on weight.
