You are safe if the winds are out of the south or west and if the fish are close. 10-20 mph should be Ok unless you start venturing off shore 3 miles or more. Be careful if the winds go NW, N or East. That same wind speed will produce 3-4 foot waves. Keep an eye on the weather, Lake Erie can go from a nice 1 foot chop to 6 footers in 15 minutes (Been there done that).
I have been going on the lake for 35+ years and I run a 30 foot boat because of that possibility.
