[1][3][5][6] The designs were built by Jensen Marine/Cal Yachts in the United States, which was owned by Bangor Punta at that time.

[1][4][7] The factory brochure for the boat describes the Mark II design goals as, "A Cruiser Built For Speed, Not Rating Points".

They both have raked stems, slightly raised counter reverse transoms, spade-type rudders, controlled by a wheels and fixed fin keels.

The galley is located to the starboard side, at the foot of the companionway steps and includes a three-burner, alcohol-fired stove and an oven, as well as an 8 cu ft (0.23 m3) icebox.

[4] In a 1994 review of the Mark II, Richard Sherwood wrote, "a Lapworth design, this Cal has a long water line, aft-extending rudder, and a substantial sailplan.

"[7] A 2008 review by John Kretschmer in Sailing Magazine described the Mark II as, "an ideal boat to consider for long-range cruising".
