Name and marketing
Hull and deck
- The construction of the C&C 37/40 was ahead of it's time. Utilizing aircraft grade pre-impregnated balsa core material and Kevlar / fibreglass fabric, the hull and deck are laid up using vinyl ester resin for strength, blister resistance and light weight. The C&C 37 Plus series are built up with isophthalic (Hydrex®) gelcoat, C&C's exclusive Kevlar hybrid, E-Glass, pre-impregnated end-grain Baltek AL-600 balsa (1 in (25 mm) balsa core in hull and .75 in (19 mm) in deck) and Hydrex® resin. Hydrex®, a modified isophthalic vinyl ester resin, has higher hydrolytic stability, toughness and is more crack resistant than conventional resins. The layups of the R and XL series use Kevlar hybrid exclusively with Hydrex® resin on both sides of a core of Balteck AL-600 aircraft grade balsa. All materials are Lloyd's approved. These exclusive C&C laminate schedules result in hulls and decks which despite significant weight reduction are stronger than the conventional glass laminates of the time. They are not only much lighter, but stiffer and more rigid. Additional unidirectional glass is used in highly stressed areas with aluminum and coremat hardware backing. The boot stripe is molded in the hull for fairness to the hull surface and to reduce maintenance requirements.
- All of the interior liners are overlaid and bonded to the hull and deck and the hull to deck joint is bonded with adhesive and then mechanically fastened with stainless steel bolts through the signature C&C slotted aluminum toerail. The fixed elliptical fin keel has an eight percent foil at the root with reduced chord and an extended trailing edge-hull fillet for interference drag reduction, and an eleven percent foil at the tip to help lower the centre of gravity (VCG). A keel / centreboard combination is an option. The D/L ratio ranges from 206 to 231, depending on model. The opening transom of the + and XL model is simple to operate and transforms to a walk through transom / swim platform including an integral folding ladder providing easy access to the water. The R version has an open transom.
Rudder and Steering
- Wheel steering is standard (though a tiller was an option on the 37R). The 5.5 ft (1.7 m) rudder is an internally-mounted spade-type with a "spitfire wing" planform. The rudder is constructed of two molded composite shells which are bonded together and injected with two-part foam for added strength. The rudder post is all stainless steel with a flat stainless steel plate reinforcing weldment positioned within the rudder. The rudder post passes through the hull with a water-tight, close tolerance fit between the shaft and the nylon bearing. The rudder post is brought up through the cockpit sole, with the steering quadrant mounted on top. The pedestal system is cable-linked with the radial driver being connected to the rudder post by a keyway and lock nuts. Access to the system is achieved via the removable fiberglass cover located in the cockpit sole. This design provides excellent support for the rudder stock. The rudder may be removed by loosening the bolt, rollers and quadrant. The rudder must be supported from below during this procedure.
- The elliptical planform keel is designed by C&C and fabricated by Mars Metal (MarsKeel). The keel is of lead alloyed with antimony for added strength and cast to exacting tolerances. In addition to providing the yacht's stability, the foil shape of the keel produces hydrodynamic lift while sailing to weather, enhancing upwind performance.
- The factory keels choices included the shoal keel with a centreboard, draft = 4.92 ft (1.50 m); a somewhat deeper shoal wing keel, draft = 5.92 ft (1.80 m); a deeper elliptical fin keel with "beaver tail" bulb shoe, draft = 7.25 ft (2.21 m); or the deep elliptical fin racing keel, draft = 7.9 ft (2.4 m)).
- The keel is fastened to the hull by means of eight stainless steel bolts of up to 1.5 in (38 mm) diameter, which are cast into the lead. These bolts project through the bottom of the boat and are bedded with sealing material to prevent water leaks. The bolts are secured by 2.25 in (57 mm) stainless steel nuts and washers which are visible in the bilge.
Mast and Rigging
- The spars are designed by C&C and fabricated by Offshore Spars. The standard boat has a keel stepped non-tapered double spreader masthead sloop rig, with rod rigging and a hydraulic backstay adjuster. A taller rig was available as an option and came standard on the R and XL variants. This tall rig is a triple-spreader mast, tapered above the upper spreaders, with all rod rigging, plus running backstays (runners), checkstays, and an adjustable babystay for mast bend control. The backstay is split, with two hydraulic rams, on the boats with walk through transom (37+ and XL). The masthead, gooseneck and boom end are custom machined aluminum, welded to the one piece extrusion. The aerodynamic spreaders are secured to the mast via machined, continuous aluminum spreader bars. They precisely fit the spreader bases and traverse the mast and along with separate support bars carry the compression loads exerted by the shrouds. On the 37R (and 37XL) mast the middle and lower spreaders are slightly swept back, 2° for the middle spreaders, 4° for the lowers.
- The standard rig has an I = 52 ft (16 m); the tall rig, I = 53.5 ft (16.3 m); and the R (racing) rig, I = 54 ft (16 m)).
- As these boats have an aft cockpit layout, for ease of handling all halyards and controls are led through rope clutches to a pair of two-speed winches (on some boats, four winches are located here) at the aft corners of the cabin top. The primary and secondary winches are positioned at the margins of the wide cockpit. Mainsheet control is through a mainsheet traveller with roller bearing car and crosshaul tackle recessed into the bridgedeck. Two inboard genoa tracks with low lead genoa cars rolling on ball-bearing travelers to permit adjustment while under-way and there are additional inboard leads for the light Genoa inset at the aft corners of the cabin.
Design and Construction Drawings
- The Marine Museum of the Great Lakes in Kingston, Ontario has in its archives many of the original C&C Design and Construction Drawings dating from 1972 through the late 80's, including at least 22 large (36 in (91 cm) x 48 in (120 cm)) drawings specifically for the 37/40 series.
C&C 37/40 R
- This model, produced from 1988 to 1990, is laid out for racing and was designed to be competitive under the then current IMS handicapping rule, as well as in PHRF fleets. The 37R hull is built with fibre-reinforced plastic using DuPont hybrid material that combines Kevlar with fiberglass. This combined with C&C's usual balsa core results in a very high strength or stiffness to weight ratio. Unidirectional glass is used for additional local stiffening. Its interior, rather than being based upon moulded pans and liners of the cruiser/racer 37/40+, is organized around a series of plywood longitudinals and bulkheads. These plywood members are rigidly glassed to the hull and contribute considerably to the strength and stiffness of the hull. The massive aluminum chainplates are bolted to sturdy plywood webs which form the back of the settees.
- The aft cabin was usually not enclosed on the standard 37R but an enclosed aft cabin version, marketed as the R+ interior, was an option, as were other cruising amenities found standard on the sister 37+, such as hot and cold pressure water and 110 volt shore power. Other factory modifications found in a number of the C&C 37R produced (including R17 and R23) were the substitutions of more exotic materials such as "F" board (Firet Coremat AE100 Marine Board) in interior bunk tops and other horizontal surfaces, and Balta-Ply mahogany / balsa composite (plywood with a core made of balsa) in interior bulkheads, doors, and other vertical structural members. These changes were intended to lighten the boats further for racing.
- The R variant has a draft of 8.16 ft (2.49 m) with the standard elliptical keel and a tall, tapered triple-spreader mast with all rod rigging, plus runners, checkstays, and an adjustable babystay for mast bend control. The R has a PHRF racing average handicap of 66 with a high of 72 and low of 63. It has a theoretical hull speed of 7.36 kn (13.63 km/h). The boat is fitted with a Universal Model 35 diesel engine of 30 hp (22 kW). The fuel tank holds 20 U.S. gallons (76 L; 17 imp gal), the fresh water tank has a capacity of 30 U.S. gallons (110 L; 25 imp gal), and the holding tank has a capacity of 12 U.S. gallons (45 L; 10.0 imp gal). It displaces 14,900 lb (6,759 kg) and carries up to 7,380 lb (3,348 kg) of lead ballast, though displacement and ballast varies by as much as 1,500 lb (680 kg) from the heaviest to the lightest, depending on how the boats were fitted out at the factory.
- A number of 37/40 R's intended for lighter wind regions had their keel's weight reduced at the factory by 500 lb (227 kg) by the inclusion of a sand pocket in the lead during the casting process. Some keels were lightened after manufacture using one of several different methods. The factory modification was to cut a window in the keel and fill it with a sand/resin mixture. Post delivery keel modifications have included shaving lead off the sides of the keel and then building it back up with micro-balloons. C&C made full size keel section drawings available to permit fairing the keel after modification and some boats were delivered with full size foil templates for the owner's use.
- The C&C 37R "Wave Train", hull number 14 in the 37R production run, built for customer Watt W. Webb, was so extensively customised by the factory that construction drawings specific to this boat were produced. Changes indicated in these drawings include the addition of a waterproof crash bulkhead forward, all interior bulkheads tabbed to the deck above, an upgraded deck and bulkhead construction, and a custom Britt Chance aluminum & lead keel fitted.
- The R version can be distinguished from their sister 37/40+ and XL by an "R" in the length code in the HIN, the exception being the first three 37R built, Fastrack (now Holo Nui), hull number 2 in the 37/40 series, the second 37R, "The Third Wave", hull number 4 in the series (scrapped after a hard grounding in 2016), and the third 37R, Andromeda (now Seacan), hull 5 in the series, which have no "R" in their HIN. Somewhere in the first 10 hulls, C&C raised the freeboard by about 1 in (25 mm) to get more headroom under the IMS rule. Over the production run 25 of the 37R were built.
C&C 37/40 +
- This model, produced from 1988 to 1994, was based on the 37/40 R hull, using the same molds for hull and deck, but fitted out with a full cruising interior. The interior layout in the C&C 37+ series was a significant departure from the standard C&C interior layout dating back to 1969 and the C&C 35 Mk.1. The biggest change involved moving the heads aft into the area usually occupied by the front half of the quarter berth. By doing this, placing the heads and galley side by side in the widest part of the boat, C&C was able to make them both more spacious and workable. This does move the main cabin forward somewhat into a slightly narrower section of the hull, eliminating the possibility of pilot berths outboard of the settees. This aft head layout was first seen in the C&C Landfall series. The other departure is the inclusion of the large, full width aft cabin, first seen in the C&C 44 from a few years previous. This was the first design in which C&C was able to fit such a spacious aft cabin into a boat of this length.
- Starting in the forward stateroom, there is a 6.4 ft (2.0 m) long centreline V-berth, with teak staving on the hullsides and louvered teak lockers along either side over the berth. There is a hanging locker to port and a second hanging locker to starboard along with a vanity with sink (hot and cold pressure water), and mirror. The starboard portion of the bulkhead opens to the salon if desired to add visual space to an already large living area. Ventilation and lighting is provided by a large overhead hatch and two overhead lights.
- Moving aft into the saloon, there is a straight settee to port, the aft end of which provides seating for the aft facing navigator's station (nav station). A removable seat back slips in to give the navigator a comfortable back rest. The nav station has drawer storage beneath it and a large chart table with ample room to spread out on it. The electronics and electrical panels are arrayed in a convenient console style.
- To starboard is a curved settee that converts to a double berth when required. An inlaid teak table with two drop leaves surrounds the keel stepped mast. There are teak shelves and louvered locker storage behind both settees.
- The entire galley/saloon/nav area is illuminated and ventilated by a large skylight, five fixed lights, four hatches, overhead lighting, four reading lights and nighttime courtesy lighting along the floor.
- Aft of the nav station on the port side at the base of the companionway is the head. A louvered teak bi-fold door provides access to the space. Built as a complete molded head unit with full headroom and good ventilation, it includes a vanity sink, marine head, an abundance of mirrored storage cabinets, and a large separate stall shower with a Plexiglas door and dividing partition. Hot and cold pressurized water system and electric shower sump pump complete the systems.
- Aft of the settee on starboard is the galley. L-shaped, it features a large top opening ice box / refrigerator, 7.6 cu ft (0.22 m3) capacity, three burner propane stove with oven, hot and cold pressure water, and a deep double centreline sink. Outboard along the hull are numerous storage spaces and lockers for storage, including organizers for silverware and dishes. Pot storage is located below the stove and there is additional storage above and below the galley sink area.
- Continuing aft past the galley is the entrance to the spacious aft stateroom. Featuring an island centerline queen berth a spacious 6.5 ft (2.0 m) x 5 ft (1.5 m) with a padded headboard. There is shelf, locker and hanging storage on both sides of the cabin. Numerous lights, mirrors, and four opening ports for ventilation and light.
- The 37/40+ displaces 17,500 lb (7,938 kg), carries 7,520 lb (3,411 kg) of ballast with the wing keel (draft of 5.92 ft (1.80 m)) or elliptical keel with small "beaver tail" bulb (draft of 7.25 ft (2.21 m)). It is also available with a shallow draft keel / centreboard combination with 7,800 lb (3,538 kg) of ballast. The boat has a PHRF racing average handicap of 75 with a high of 75 and low of 75. It has a theoretical hull speed of 7.36 kn (13.63 km/h). The boat is fitted with a Universal diesel engine of 30 hp (22 kW), although a Yanmar diesel engine was a later option. The engine has full access on three sides. The fuel tank holds 44 U.S. gallons (170 L; 37 imp gal) and the three fresh water tanks have a combined capacity of 79 U.S. gallons (300 L; 66 imp gal). Over the production run 65 were built.
C&C 37/40 XL
- This model, the "XL" (Extra Light), produced from 1989 to 1994, is built using the 37/40 R's lighter hull and deck, 40 percent lighter than those of the plus series, combined with the R's deeper keel and taller triple-spreader rig. It is in the XL's interior where this model differs from the 37R, as the XL is fitted out with the fully equipped cruising interior of the 37/40+ . The XL displaces 16,500 lb (7,484 kg) and carries 6,520 lb (2,957 kg) of ballast. The boat has a draft of 8.16 ft (2.49 m) with the standard fixed fin keel and 4.92 ft (1.50 m) with the optional centreboard/keel (centreboard up). The boat has a PHRF racing average handicap of 105 with a high of 109 and low of 78. Over the production run 15 of this variant were built.
