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. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.
