Hi Dennis,
Greetings from Holland, MI. I just came across your original post regarding the Core Sound 15. My wife and I have just gone through a similar decision process and are having a Jim Michalak 17' yawl built beginning in October. The CS 17 was high on our list, but decided that the Michalak cockpit fit us better. We've sailed the Great Lakes and beyond on larger boats since 1970, but are looking forward to a simpler way to go. Perhaps we should keep in touch.
