I have a Raymarine S1G. Just did the solo Chicago to Mac with it and no problems. Actually have done 3 Solo Macs with it. Going through all the configs is well worth it.
Yes heavy air is a problem, but it did great steering on wind vane seeting for me upwind and down. Reaching on windvane doesnt seem to work that well.
BTW 2 J30's completed the Solo Macs (Chicago and Port Huron) this year. My Dog Bob from Georgian Bay did it as well.
