About your last example, I wonder if it may be related to the fact that the boat was in the Blue Water Rally? This rally keeps up a pretty relentless pace and the boat mentioned would be near the bottom of the fleet speedwise. Would be very wearing on the crew, especially people in their 60s (and I am in my 60s so not a knock) since the port stays for rest and repair are much shorter than for faster boats in the fleet. Also might encourage the slower boats to push too hard so they get to port sooner. I understand that the Blue Water Rally is no more - don't think it is much of a loss.
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!
