michigan law says one needs to be present on all flotation crafts.. i carry min with me but do not wear it.
Going without a life jacket, would be a foolish venture. Legal or not, please protect yourself and your family. I normally have mine stuffed in the Kayak. Even though I am an excellent swimmer, I should have it on, regardless of skill. But I believe it's only required to be in the boat, one per person. The park office should have life jackets you can rent.. they aren't that expensive though, you can pick them up almost anywhere in the summer. The park office can also clarify the legal aspects of wearing lifejackets.
