The Whistling Straits courses of the American Club at Kohler are the "Irish Course" and the "Straits course". Both courses, in fact all courses at the American Club were designed by Pete Dye.
The Irish course is routed like an inland links, whereas the Straits course is along the shores of Lake Michigan. The Irish plays to 7,201 yards from the back tees with a 146 course rating, and opened in 2000. The Straits Course is 7,288 yards, a 76.1 course rating and a 151 slope, and opened in 1998. The fairways and the greens run fast and hard, and are bordered by tall fescue grasses on rolling linksland type terrain, and is as natural of a setting as you will find. The wind is generally a big factor, much like the links courses of the British Isles. Stunning scenery throughout, play in the late afternoon for a real treat, and be sure to take a caddie.
