CS 27 is a 27 ′ 0 ″ / 8.2 m monohull sailboat designed by Raymond Wall and built by CS Yachts (Canadian Sailcraft) between 1975 and 1983.
Rig and Sails
Auxilary power, accomodations, calculations.
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.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
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.
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.
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.
Ballast / Displacement * 100
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.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
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.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
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.
CSV = Beam ÷ ³√(D / 64)
The optional shoal draft model has a longer bolt-on lead keel. Draft: 3.92’/1.19m Displacement: 6500 lbs./2948 kgs. Ballast: 2800 lbs./1270 kgs. Sail Area/Disp.: 15.71 Bal./Disp.: 43.08%;Disp./Len.: 212.02 About 90 boats were fitted with these lead fins. In 1977, the rudder area was increased. CS also offered owners a rudder retrofit kit that added two inches to the forward edge to improve helm balance. Three years later, the mast was changed from a Proctor to an Isomat section, the fibreglass cabin sole was replaced with teak and holly , and cupboard doors were finished with woven cane fronts. The Yanmar YSE was replaced with the 1GM as standard equipment. Drawing shown here is from introductory brochure.

The Cs 27 is a 27.0ft masthead sloop designed by Raymond Wall and built in fiberglass by CS Yachts (Canadian Sailcraft) between 1975 and 1983.
480 units have been built..
The Cs 27 is a light sailboat which is a reasonably good performer. It is stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat.

Designed to determine if a boat has blue water capability. The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less.

The CS 27 is a small recreational keelboat, built predominantly of fibreglass. It has a masthead sloop rig, a transom-hung rudder and a fixed fin keel . It displaces 6,100 lb (2,767 kg) and carries 2,400 lb (1,089 kg) of ballast.
The CS 27 is a sailboat designed in the mid seventies. The CS 27 is built by the Canadian yard C S Yachts Ltd. . Here we would have liked to show you nice photos of the CS 27.

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 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. Mark III (hull #s 435-915) (1974-1981. (See C&C 27 MK III)

The C&C 27 Mk I aka Korneuburg 27 is a sailboat designed by the maritime architect Robert W. Ball in the early seventies. A few hundred boats have been produced. The C&C 27 Mk I is built by the American yard C&C Yachts.
CS Yachts models included the CS 22, designed by John Butler. Raymond Wall, the former chief designer for Camper Nicholson, was CS’s chief designer from 1977 to 1983. His CS 27 was followed by the 36, and finally the 33.
