I own a slip at Anchorage Marina on Lake Macatawa in Holland where several slips are available to rent, including mine next season. Anchorage has nice bathroom and shower facilities, laundry, pool, clubhouse. It's on the north shore of Lake Macatawa, about a mile from the Lake Michigan channel.

Anchorage Marine Services will haul out and service your boat. Winter storage is available on site.
