Hull Speed
8.0 kn
Classic: 7.03 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

8.03 knots
Classic formula: 7.03 knots
Sail Area/Displacement
19.2
16-20: good performance

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

• SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D: Displacement in pounds.
19.22
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
47.6
>40: stiffer, more powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

47.62
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
225.6
200-275: moderate

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet
225.57
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
23.6
20-30: coastal cruiser

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

• D: Displacement of the boat in pounds
• LWL: Waterline length in feet
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet
23.55
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.9
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

• Beam: Width of boat at the widest point in feet
• D: Displacement of the boat in pounds
1.93
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

First called the REDWING 35 and built by Hinterhoeller Ltd. a development of the INVADER 35. It was renamed the C&C 35 when Hinterhoeller was merged with C&C Yachts.

In 1973 a re-designed model was introduced, later designated the C&C 35-2. (or Mk II). In all, 351 C&C 35s were built. Production for the C&C 35-2 ended in 1975.

Differences between the 2 versions:
The nearly one foot increase in length of the Mk II is a result of raising the sheer several inches. In addition, the scimitar-shaped rudder of the MkI was replaced with a more conventional, partially balanced spade. The after sections of the MkII were reshaped to reflect the then-current IOR design trends, sail area was increased by a little over 50 square feet and an additional 620 pounds of ballast were added.

The deck and cabin house of the MkII were also modified eliminating the integral spray rail on the cabin top that was a prominent feature on the MkI. The cockpit was changed to a “T” configuration, and a bridge deck added for the mainsheet. The interior was spruced up to make it a little more yacht-like in appearance and, last but not least, all these changes resulted in a 30 % increase in displacement to 13,800 pounds, and draft increased from 5’ 3” to 5’ 6”.

Construction of the 35 is a solid glass hull with balsa cored deck.
The interior is similar between the MKI and MKII models. The galley and navigation station are flip-flopped on the two models with the MKI having a starboard side galley aft and a port side quarter berth/navigation station combination. Both models have a fiberglass cabin sole and minimal bilge area.

The Universal Atomic 4 gas engine was the standard auxiliary power for both models. Some of the later MkII models were offered with Westerbeke diesel engines.

From 1983 to 1987 C&C built another 35 model, referred to here as the C&C 35 MKIII, which is an entirely different design.
