After the first CROWN 34's were built, Calgan Marine sold the molds to GlassFab of Monroe, WA.,USA. A few were then manufactured and sold as the SUN 1030. Later, the molds were repossessed by Calgan and then sold to Clark Boat Co. USA. With a few modifications they were then built and sold as the SAN JUAN 34.
