C&C Yachts was a builder of high-performance fiberglass monohull sailboats with production facilities in Canada, Germany, and the United States.

They started by designing a small number of steel and wooden boats, with Cuthbertson doing the preliminary lines and calculations and Cassian the interior plans and details.

[6] The boat, named Red Jacket, was built by Bruckmann Manufacturing of balsa wood sandwiched between two layers of fibreglass.

Red Jacket is considered to be the first sailboat engineered with a cored hull (the practice is common in yacht-building and aerospace, even in the manufacture of wind-turbine blades today).

In the operation conceived by Hinterhoeller, the yachts were built in pits, as opposed to the state-of-the-art which required a boatbuilder to use a ladder to mount the erected hull and keel.

In 1971 hull #1 of the 43 ft (13.1 m) "Limited Edition" series, Arieto, won first in Class B of the SORC, and the Montego Bay Race.

[1] During the formative years of C&C Yachts the company sold their early racing hull molds to build capital for development of a comprehensive line of C&C branded racer/cruisers.

[1] The demands of managing a large multi-national company, with the attendant problems of finance and being answerable to a board of directors, in 1973 led Cuthbertson to take on the position of president, and hand over his design responsibilities to Robert Ball.

[7] High oil prices and a strong Canadian dollar provided the environment for rapid growth for C&C and the entire sailing industry.

[4] Hank Evans joined the company in 1977 to establish a network of inland dealers and once that job was done he stepped into the role of sales manager for the entire line.

[2] Designer Mark Ellis left the company in 1976 to draw the Niagara and Nonsuch sailboats for George Hinterhoeller, who had sold his shares in C&C that same year.

The Canada's Cup winner in 1978 was a C&C design, the Two Ton class Evergreen,[14] owned by Don Green with Hans Fogh at the helm.

The deck hatches opened inward, which could be a safety hazard if they gave way during a capsize or broach, and the Evergreen crew faced protests over this defect in both the SORC and in the Canada's Cup.

After the competition that year, the rule books were rewritten to preclude safety problems like those raised by the design of Evergreen, and as a result, C&C never received another commission for a Canada's Cup yacht.

[4] The success of the 1980 financial year, including sales of $39.7m, delivering a profit of $1.24 per share, brought the unwanted attention of a C&C customer, Jim Plaxton[4] of Great Lakes Airlines fame, who was interested in buying the company.

[15] The owner and operator of Silver Shadow III, Plaxton,[22] "decided not to participate" in the 1983 Admiral's Cup,[20] and his yacht's place was taken by another C&C boat, Magistri, which was also designed in 1982.

[4] In 1985, under Ball's supervision, C&C's design office had grown to eleven staff,[25] and the firm experienced its racing nadir, with the poor performance at SORC of the company-backed custom 44 Silver Shadow IV,[4] also a 12'11" beam but on a lengthened 43'7" long yacht.

[4] In the late 1980s rising costs and a shrinking market caused the closure of many boat manufacturers, including Quebec-based Tanzer Industries and Mirage Yachts.

[citation needed] In September 2013, US Watercraft announced that it had bought the rights to the C&C brand from Tartan and would take over manufacturing of all new C&C models starting in the fall of 2013.

[30] US Watercraft entered receivership in July 2017 to sell its assets, but by the summer of 2018 no buyer had been found, the C&C website had been blanked and production of the last two models, the Redline 41 and C&C 30 One Design ended.

[31][32] The Marine Museum of the Great Lakes in Kingston, Ontario has in its archives the early original C&C design and construction drawings, a retirement donation by Cuthbertson of his papers.

[33] Cuthbertson died at the age of 88 on 3 October 2017; he had served on the board of directors of the MMGL for many years, and had been inducted into the Canadian Sailing Hall of Fame in 2014.
