We took my kids kayaking and canoeing around your S' age. I think it'll be ok really. If they have life jackets, and you stress safety. My thinking is that if you have more experience, you should try to take your sons kayaking and canoeing with you so that you can teach them all the rules of safety and help ensure their safety on trips with W. Look at that as something fun you can do with them. Do they also swim and know how to float and all that? If not, you could teach them to swim also or have them take lessons this summer? Karen
