Jim,
I dock Valkyrie in the western basin of Lake Erie and fish the islands area regularly. i would suggest that you don't dock in the Sandusky area for a for reasons. The biggest is that you will have a six mile daily run out of Sandusky Bay which is shallow, choppy and has lots of boat traffic, both pleasure craft and freighters leaving the coal docks in Sandusky Bay. That run is a pain! Another is that Sandusky is not that nice of a town and there is a gang problem.
I suggest that you dock at my marina, Bass Haven, in East harbor on the Marblehead Peninsula, just east of Port Clinton. East Harbor is a mile long and a mile wide, at its largest, and it's a mile run to the lake through a very protected channel, unless its blowing NE. Also, that will put you six ,miles from Kelley's Island and 13 from South Bass Island (Put-in-Bay). The the Bass Islands are also close.
Bass Haven is a nice mom-and-pop marina and the folks are friendly. Bait shops, stores and restaurants are fairly close in this rural area as are ramps. Bass Haven has a lift, but no ramp.
We are going to be cruising the Carolinas in May, but if we are around I'll be glad to help with the local knowledge. The bait shops are your best bet for fishing info.
BTW: About 3-4 years ago someone from your area asked the same questions and got these same answers, but never made the trip. Was that you?
Regards,
Nick
