The Cal 24 is an American trailerable sailboat that was designed by C. William Lapworth as a Midget Ocean Racing Club (MORC) racer and first built in 1958.{{cite web|url= https://sailboatdata.com/sailboat/cal-24|title= Cal 24 sailboat |access-date= 26 January 2021|last= McArthur| first= Bruce |work= sailboatdata.com|year= 2020|archive-url= https://archive.today/20210126151730/https://sailboatdata.com/sailboat/cal-24|archive-date= 26 January 2021|url-status= live}}{{cite web|url= https://sailboatdata.com/designer/lapworth-c-william|title= C.

The boat was one of the first fiberglass boats produced and the first Cal Yachts brand design produced by Jensen Marine.

The design was originally marketed by the manufacturer as Cal 24, but is now usually referred to as Cal 24-1 to differentiate it from the unrelated 1967 Lapworth Cal 2-24 design and the 1983 C. Raymond Hunt Associates-designed Cal 3-24. At the time of their market introduction each of these designs were sold under the designation of Cal 24.{{cite web|url = https://sailboatdata.com/sailboat/cal-2-24|title = Cal 2-24 sailboat specifications and details|access-date = 26 January 2021|last= McArthur| first = Bruce |work = sailboatdata.com|year = 2020|archive-url= https://archive.today/20210126151928/https://sailboatdata.com/sailboat/cal-2-24|archive-date= 26 January 2021|url-status= live}}{{cite web|url = https://sailboatdata.com/sailboat/cal-24-hunt|title = Cal 24 (Hunt) sailboat specifications and details|access-date = 26 January 2021|last= McArthur| first = Bruce |work = sailboatdata.com|year = 2020|archive-url= https://archive.today/20210126152131/https://sailboatdata.com/sailboat/cal-24-hunt|archive-date= 26 January 2021|url-status= live}}
