Dear Stuberg, There is a Michigan C-Dory dealer. Deck and Docks in Walled Lake/Sylvan Lake, near Pontiac. They often have a boat or two in stock. They are in an area of many small lakes and their main inventory seems to be pontoon boats, but still. I love my C-Dory. I ended up choosing the 22 over the 25. I thought I wanted the 25 with head and self bailing cockpit but that cockpit was just too shallow. The 22 is for two or three people, more if they are real friendly and maybe some on the small side.
If you plan to keep the boat in a slip then you might want to consider some other pilothouse boats like Sea Sport, Osprey, etc. These are heavier, more expensive boats and would cost more to operate but they would be more comfortable (not any safer, that is mostly on the skipper) on the big lake many days. Now I expect Al (Moose) to contradict this assertion and he is both much handier and more handsome than myself. A 22 footer in those lines will weigh about the same as a 25 C-Dory. Now if you plan to trailer the boat often than you can't beat the C-Dory and look hard at the 22. I am often at Manistee, my next planned trips are to GT Bay and then the straits area. GT Bay is a pond compared with lake at Muskegon or Manistee.
There is a wealth of info here and on the C-Dog site browse around you will enjoy it.
