The Crown 28 is a Canadian sailboat, that was designed by naval architect C. William Lapworth in conjunction with Calgan Marine founder Al Nairne and first built in 1976.[1][2][3]

Calgan Marine had produced several Cal Yachts designs under licence and the Crown 28 is a development of the 1974 Cal 2-27.[1][3]
