The Viking 28 is a 28.17ft masthead sloop designed by Cuthbertson & Cassian and built in fiberglass by Ontario Yachts between 1968 and 1983.
147 units have been built..
The Viking 28 is a moderate weight sailboat which is a reasonably good performer. It is very stable / stiff and has a good righting capability if capsized. It is best suited as a day-boat.

Viking 28 is a 28 ′ 2 ″ / 8.6 m monohull sailboat designed by C&C Design and built by Ontario Yachts between 1968 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)
This was the first of the C&C-designed Viking series built by Ontario Yachts. The VIKING 28 was also built by Anesty Yachts in England and renamed the TRAPPER 28/400. 70 were built along with a number of other C&C designs including the C&C 27, called the TRAPPER 27, and the C&C 35. Although initially offered in kit form, many subsequent Vikings were professionally finished. A number of modifications to the design were made in 1974, and included the addition wider companionway with a pop-top hatch. The mast step area and vee-berth were altered to strengthen the hull. The VIKING 28 was available with either an outboard well, or a 7 hp Vire two-cycle gasoline inboard. Photo courtesy Adam Hunt.
