Great Lakes-Summer SAILING not MOTORING

[Photomon]

Wife and I live in Virginia and want to charter in the Great Lakes. Have never sailed the Great Lakes but have chartered in the summers elsewhere and spent too much time MOTORING and not enough SAILING.

I checked Wunderground for historical June-August wind info for Lakes Ontario and Erie and concluded (based on the numbers) that we would probably not have a rail in the water much of the time. However, numbers do lie.

Anybody have a recommendation on where and when in the Great Lakes June-August we might charter for a week and spend most of it sailing rather than motoring? (With whom we might charter would help as well but where and when is most important!)
