Seriously, have some JB Weld onboard. Great stuff. We have a fiberglass tape-reinforced JB Weld repaired pipe nipple on our exhaust system that has now gone halfway around the world. It started as a temporary repair and just seemed so secure that we left it alone even though we have the spare part onboard.
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!
