There is not enough info here to suggest whether it is suitable or not. You can't just go on the basis of LOA and age. The design matters a lot as does how it is equipped (furlers on headsails, how easy is to reef the main, etc)
Heading back to Lake Ontario for this summer. Relatively few stops along the way from Grenada. Martinique, Guadeloupe, St. Martin (must have something to do with the French food), then Bermuda, New England and up the Hudson/Erie Canal. We were going to go via Newfoundland and Labrador but June remembered that one of the kids is getting married this summer - details, details!
