My choice would be the
C&C 27, either Mk III or Mk IV, or the
Ontario 28, if you can find one. For
offshore work (ie. blue-water), the CS 27 is a better choice, but on the
Great Lakes the
C&C and
Ontario designs are more family-friendly and well-suited to the light airs. The Mirage 27 has an attractive
cabin interior design, but the build quality is not up to C&C or Ontario Yachts standards. Also, the
rudder is a bit under-sized and easy to over-power, so you need to always be ready to dump the
mainsail.
Catalina 27's are nicely built
boats and very
family friendly, but their sailing qualities are not quite up to C&C and their
engine access is terrible. Otherwise a good choice as a floating, traveling cottage. You might also consider a Tanzer 29, which is an innovative design and quite well-built.
These
forums tend to be very unkind to the Atomic IV
engine because the predominantly American
membership has a bias towards diesels. After living with one for 17 years, I can attest to their quality and durability. They are simple to maintain and very reliable. In 45 years of
crewing and sailing on the
Great Lakes, I have only ever heard of one Atomic IV
installation blowing up, and that was because the
skipper did not bother to run the blower after refueling in mid-lake. On the other hand, the power-boat club upstream from me has had 3 explosions in the last 8 years. Of course, none of those were Atomic IV engines. I am respectful of my Atomic IV and its gas tank, and consequently have total faith in them.
