Imported by, and part of the Seafarer (USA) line.
Available as sloop or yawl. (sitka spruce spars)
Hulls were molded in Europe and some were finished and sold there.
Some time later (1966?) the molds were purchased or leased to a firm in the UK. (Dock Plastics?) and a similar boat was sold as the SANTANDER 30. How many of this later version were built is unknown (to us).
