I agree that having some sail up would help make the boat more comfortable. Good idea to check out reefing system and furler before you need it. If the genoa is strong enough cloth having it almost fully furled (a few feet out only) gives one an almost flat sail to work with. CE is a long way forward but not much you can do on a sloop.
As to cloud color, I was at a yacht club near Cleveland many years ago when there was a tornado watch in effect and the clouds included distinct patches of yellow and even green. I imagine a meteorologist would be able to explain why these colors appear.
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!
