I emailed the curator at the Maritime Museum of the Great Lakes to see about copies of C&C 27 Mark II 1974 drawings. They wrote back that they only found two for a 1974: a sail plan and an accomodation plan, no mention of the Mark on them. They could research further for an hourly fee if I sent photos, or just send what they have for about $20. I would imagine that earlier Mark I drawings would apply to a 1974 Mark II, for the most part?

By C&C's reckoning, there only ever were a Mark I, which we call the I and II, and the Mark II, which we call the III and IV. The Mark I/II designation was only ever used internally, not to the market. Your "Mark II" is by C&C's numbering, a Mark I with detail enhancements.

The curators sent me a list of their C&C 27 holdings up to 1974. It isn't easy deciding what to ask them to send for my 1974 "Mark 2". (David, Thanks for your clarification about the way C&C used the term "mark" inside their operation. The curators were very interested in that tidbit too. I'll use numeral "1, 2" for our consumer Mark, and Roman numeral "I" for their internal Mark).
These are the design terms used in the list:
"Mark 22 I" 22' 3" L.W.L.
"Mark 21 I" 21' 0" L.W.L.
"Mark I"
"C&C27" 21' L.W.L.
"C&C27 trapper 500"
"C&C27 tall rig"
"Hinterhoeller"
Some archive file labels specify the term "LWL" after 21 and 22, so those must be waterline lengths for the model with an overall 27 foot length (C&C 27). The actual labelling varies: "Mark 22 1" 22' 3" LWL sloop", "Mark 21 1" 21' 0" LWL sloop" and "Mark 1 sloop". Could the 21'0" refer to our Mark 1 and 2, and the 22'3" to our Mark 3? I recall measuring 25 feet at the waterline last summer with a tape measure, but that must not be the marine architectural standard?
Would the iron ballast fo the C&C 27 Trapper 500 apply? My Mark II has a lead keel.
The "C&C 27 tall rig" sail plan presumably applies to my "Mark 2"?
The "'Hinterhoeller' accomodations" drawing presumably is just a standard C&C 27 accomodation?

The 21' 0" L.W.L. should refer to a Mark I hull, which is what we call the Mark I and Mark II (a Mk I with taller rig - see "Evolution"). The Mark II hull, which we call the III and IV, has an LWL of 21'8" or 22'-10.5" depending on whether you look at the original drawings or C&C's marketing description (which is what we use in the Assoc.). The Trapper should be a simple Mark I (by anyone's numbering) and the Trapper pages suggest that Trapper made the keel switch themselves.
I cannot comment intelligently on any of the other variations, except to say that if your waterline length is 25 feet, you have entirely too much stuff on board.

Hmm, I double checked David, now the boat is indoors in the shop: the length along the bottom edge of the oiriginal red gelcoat bootstripe on our Mk II is indeed 25 ft, so the mystery persists.

Are you measuring the curve of the hull, too?

Yup. So the correct dimension is linear midship on the waterline, which of course would be much less than 25 feet, and so 21 feet makes sense. Doh.

Measurements like this are sometimes described as straight-line distances between perpendiculars erected over the measurement point (though in the case of measuring a boat out of the water it makes sense to drop the perpendicular). Sorry I didn't pick up the confusion earlier.

David, My error entirely. Thanks for keeping an eye on it.
Cheers to all for Christmas. I painted the engine red yesterday - just in time for Santa, although that was a pleasant coincidence.
