North of Mackinac Island and St. Ignace are two bays...Saint Martin and Horseshoe.  Does any body have anchorage etc information about these areas?  We plan on putting in a St. Ignace August 14 and sailing around a bit before spending 2 nights on Mackinac Island and then de-launching on August 21/22.  Any suggestions on where to anchore and visit?  28 ft. Trimaran, only need 2 feet.

Thank  you
