Others have hinted at it, but I will just say it. Kayaking lake erie in early may is a bad idea. The water temperature will most likely be mid 40's to maybe 50. This is no time to take a chance. If you wear survival suits, have at it. If not the chances of survival "if" something happens gets pretty slim, and the chances of something happening in a kayak on lake erie are good. I do not care what the air temperature is, if the lake temp is 45 you have to dress for 45 weather. There are many on this site and other sites as well as many charter captains, head boats, etc that you can go out with in the spring. Plan your lake erie kayak trip for when the water temp is 60F or above. Take a ferry out to the islands with your kayaks and catch small mouth, largemouth, catfish, sheephead, walleye, perch, etc all day long in enjoyable weather. Do not chance your life or the life a minor under your supervision in early spring in a kayak. Can it be done, sure, but should it be done???? My 2 cents is don't do it.
