Frankfort, south of the Manatous, is a lovely village--actually part of twin villages, Frankfort and Elberta--with a clean and handsome marina. Marinas are all different, most Michigan harbors have a municipal marina with some State aid and consistancy. Most of these compete with private marinas and yacht clubs for docking business.
Docks, or slips, are far from uniform in each marina. The traditional slip consists of pilings that one loops lines over at the four corners of a boat. Most marinas have some variation of this, usually offering cleats or loops in addition to pilings for tying dock lines. Some marinas have floating docks, which are lower than the normal docks fixed to posts. We've also docked on walls and ends of docks when slip spaces are filled.
