The Evolution of the C&C 27 Cruiser-Racer
C&C Yachts produced four versions-and nearly 1,000 hulls-of its popular C&C 27 boat. Called the C&C 27 Mark I, Mark II, Mark III, and Mark IV, these boats differed in various ways, but the hulls were similar. A fifth design, the C&C 27 Mark V, was a totally different design. Heres a look at the various editions of the C&C 27, and how they differed from one another.
Mark I: Production ran from 1970 to 1972; hull numbers 1 through 167. Shorter hull and shortest rigs, with single upper and single lower shrouds. Mainsail traveller mounted aft in cockpit. Standard equipped with tiller steering and Atomic 4 gas engine.
Mark II: Production ran from 1972 to 1974; hull numbers 168 through 451. Same hull and sail area as the Mark I. High-aspect rig was two feet taller than Mark I. Rigged with one upper and two lower shrouds. Same aft traveller, Atomic 4 engine, and tiller steering as Mark I.
Mark III: Production ran from 1974 to 1981; hull numbers 452 through 914. Hull similar to previous editions but six inches in length were added to cockpit/stern area. Traveller was moved forward to bridgedeck mount, and wheel steering became an option in 1975; diesel power became option in 1978 (Yanmar). Draft and sail area increased; ballast decreased; displacement remained same as previous marks. Rudder redesigned with higher aspect shape. Small interior changes made but basic layout the same as marks I and II.
Mark IV: Production ran from 1981 to 1982; hull numbers 915 through 979. Most changes in Mark IV were cosmetic; teak interior replaced with off-white melamine, trimmed with teak and dark-anodized aluminum. Forestay moved aft about seven inched to make way for a bow roller. Auxiliary power option upgraded to two-cylindar Yanmar.
Mark V: Production ran from 1984 to 1986; hull numbers 1 to 169 (Niagara-On-The-Lake plant) and 500 to 610 (Rhode Island plant). The Mark V is a completely different boat than the other 27s; it is not considered part of the evolution of those previous designs. Geared more toward racing sailors, the Mark V was designed to meet the Midget Ocean Racing Club (MORC) rule.

To keep George Cuthbertson's design current, C&C produced four versions of the original 27. Internally, C&C only used the Mark I and Mark II designations, the first for the original hull-form and the latter for a stretched and subtly reshaped development from the original. Other changes were made, however, and to recognize the changed character of the boat, 27 sailors have designated these as the Mark I, the Mark II (aka, the Mark IA "Tall Rig"), the Mark III and the Mark IV. After production of the Mark IV ceased, C&C introduced a completely new boat named the C&C 27; this boat, described in Sea Change , is generally known as the Mark V.
In addition to descriptions of the changes made to the original design through four variations, this page includes:
- general specifications ,
- genoa and spinnaker specifications and
- mainsail specifications .
The images on this page show the C&C 27 Mark IV; see the Overview page for images of a Mark I and Sea Change for the Mark V. Photos showing notable differences in the versions are shown on the Guide pages.
Mark I: Hulls 1 to 215 were produced from 1970 to 1972. The Mark I's had the slightly shorter hulls, and the shortest rigs with two side shrouds, (one lower and one upper). Their mainsail travellers were aft in the cockpit. They all had tillers, and Universal Atomic 4 gas engines. A few of the very first hulls were built under licence by Hinterhoeller Yachts.
Mark II: Hulls 216 to 451 were produced from late 1972 to 1974. The Mark II hulls were the same as the Mark I's. Their sail area also remained the same but they had a two-foot-taller, "higher-aspect" rig, and their standing rigging now had 3 side shrouds (two lowers and one upper). The aft-travellers, tillers, and Atomic 4 gas engines also remained the same.
Mark III: Hulls 451 to 914 were produced from 1974 to 1981. The Mark III was really cast from a new mould. The hull was stretched, with six inches added to the cockpit/stern area, but no change in the beam. Draft was increased, ballast was decreased, and the overall displacement remained the same. The rig height was again increased by another 2 feet, this time with an increase in sail area. The rudder took on a higher aspect shape. Early Mark III's had clear port lights with aluminum casings. These were later replaced by a recessed design with smoked acrylic. Later hulls had an anchor locker in the bow, and lifelines became toe rail-mounted. Small changes were made to the interior detailing, but the basic layout remained unchanged. A key change in the Mark III was that the cockpit was lengthened, and the traveller was now mounted forward. This opened up the cockpit, and wheel steering became the popular option in 1975. Diesel power became available in 1978, and by the end of the Mark III's run, the single-cylinder Yanmar diesel had become standard.
Mark IV: Hulls 915 to 984 were produced from 1981 to 1982. The greatest change was cosmetic, with the primarily teak interior giving way to the style adopted in the rest of the C&C line: off-white melamine trimmed with teak and dark-anodized aluminum mouldings. Reportedly, there was consideration to marketing the boat as the Landfall 27 ( Landfall distinguished C&C's purely cruising-oriented offerings from the cruiser-racers that were the foundation of the company's reputation). Other substantial changes included setting the forestay back about seven inches to accommodate a bow roller and upgrading auxiliary power to a two-cylinder Yanmar (though many boats were built with gas engines).

The C&C 27 (MK I-IV) was one of C&C Yachts most successful model. Almost 1000 were built over a period of nearly 10 years. (Until 1982) Mark I (hulls 1-167) (shown here) Mark II (168-452), produced from 1972 to 1974. Same dimensions as Mark I, except for a taller rig though with same sail area and other minor changes.

The C&C 27 MK V is a new design replacing C&C's earlier 27 footers. It was built in Canada as well as the US. The Yanmar diesel was an option. Shoal draft: 3.5'/1.067m. Disp. 4080 lbs./1852 kgs.

LENGTH: Traditionally, LOA (length over all) equaled hull length. Today, many builders use LOA to include rail overhangs, bowsprits, etc. and LOD (length on deck) for hull length. That said, LOA may still mean LOD if the builder is being honest and using accepted industry standards developed by groups like the ABYC (American Boat and Yacht Council).
