I'm not sure where you intend to sail but starting from Leaminton I'm going to assume you're destinations will be in the western basin islands and perhaps the Ohio
shore communities including Cedar Point.
Make sure you have proper charts
as there are many reefs
and other shallow areas to avoid, some seemingly out in the middle of the lake.
Put in Bay is a great destination
even with a family if you visit on a weekday. I would avoid the place on a Friday or Saturday night. Be careful as you approach. There is a narrow channel on the south side of Ballast island as you approach Put in Bay. Also, make your final approach to Put in Bay on the east side of Ballast island. The west side is waist deep in some areas. During the week you should not need reservations, except possibly Bay Week. Kelleys island is also a very nice island to visit, a little more laid back than Put in Bay. We like to rent a golf cart and tour the islands. We prefer to stay at Portside Marina.
Cedar Point Marina is very nice and right adjacent to Cedar Point amusement park.
Don't forget to check in with US Customs
I hope this is the type of info you are looking for. If not, post your questions. I've been boating
that area for many years.
