Dick and Irene Steffen owned a yacht dealership for C&C Yachts in Pointe Claire, Quebec. The company had been very successful selling C&C boats, but the C&C line did not offer a boat smaller than the C&C 27 at that time. Dick Steffen was a competitive sailing racer and thought that there would be a good market for a C&C-built 24 foot keelboat for MORC racing. At his request Cuthbertson & Cassian designed the boat, but decided not to proceed with production at C&C. Steffen bought the design from them and founded Mirage Yachts in February 1972 to build the boat.[5]
The Mirage 24 sold well and the company soon had 15 employees building the boat model in their rented second floor facility in Pointe-Claire. One factor driving the Mirage 24's strong sales was its racing record in MORC class events. Even 15 years after its introduction a Mirage 24 won the production boat division in the MORC national championships.[5]
Caught off guard by the success of the design, C&C decided to produce a competitor, the C&C 25, which was very similar to the Mirage 24's design. The Mirage 24 continued to sell well and usually beat the C&C 25 in competition.[5]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. The galley is located on the starboard side at the companionway ladder. The galley is equipped with a two-burner stove, icebox and a double sink. The head is located just aft of the bow cabin on the port side. Cabin headroom is 57in (145cm).[4]
It is a masthead sloop and performs well in medium winds.[6] It was also available in a short mast version, and a tall mast version.[7][8]
