[Hinckley2019]

Cruising from Georgian Bay to the North Channel to Mackinaw Island this summer. Plans are to find a full service marina (haul, preferably indoor storage, access to a diesel mechanic) where we can store our 40' boat for the winter. If any one has any recommendations for a full service marinas near Cheboygan,MI (50 mile radius from this area would be fine) I would appreciate your thoughts. Thank you-

Disappointing you have received no replies. I for one would be interested. Hope to be in the area with the trailer trawler in August. First hand knowledge is always valuable.
