Excalibur Marine Corp.

Excalibur Marine Corp was a short-lived but influential American boatbuilding company based in Costa Mesa, California, active in the mid-1960s during the explosive growth of fiberglass sailboat production. Owned by Tom Pearson, the firm focused on affordable, trailerable cruisers for the burgeoning West Coast recreational market. Excalibur Marine is best remembered for producing the Excalibur 26, a William Crealock-designed sloop that marked one of the first commercial successes for the renowned naval architect. The company built approximately 25 hulls before financial challenges led to its acquisition by Wayfarer Yacht Corporation in 1963. This short tenure (likely 1962–1964) positioned Excalibur as a bridge between wooden prototypes and mass production, embodying the era's shift to durable, low-maintenance fiberglass boats.
Excalibur Marine's legacy endures through the Excalibur 26, which continued production under subsequent owners, totaling over 225 units. It reflects the "Fiberglass Triangle" of Costa Mesa—near neighbors like Ericson and Islander Yachts (your prior queries).
