Jeff, I wonder if the boat your questioner is referring to is a Glibert 30? They were interesting-looking boats but did not sell very well as they were a bit pricey. The questioner also mentions 65* tacking angles. If this is 65* each side of the wind there is a definite problem. If it is 65* in total that would be highly impressive in a cruising boat.
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!
