Well we circumnavigated South Bass Island. It's not the planet, but it seemed big in a 170. The wife and I left from Catawba State Park on Lake Erie. We went clockwise around the island and got back to Catawba as the sun was setting. It took us about 7 hours. 1 1/2 hours was in three footers... that was pretty awesome water over the bow, spray in your face fun! Good steady SSW wind all day. I need to get a spinaker for down wind. Who else went sailing this weekend?
