I was surprised about the number of boats crossing the Pacific with a dinghy on davits - starting with all of the multihulls and including a reasonable number of monohulls. Many of the monos had vane steering which makes davits extremely difficult if not impossible. I would put on a cover, perhaps with supports under it (plastic pipe comes to mind). Also make sure the drain is open.
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!
