Spencer 35 Ketch Rig
Description
The Spencer 35 is a classic Canadian-designed fiberglass cruising sailboat from the 1960s–1980s, known for its traditional lines, solid bluewater capability, and offshore track record. Designer John Brandlmayr created it for Spencer Boats Ltd. in Richmond, British Columbia. About 64 hulls were built (some sources note production from ~1962 to 1983), making it semi-custom with variations in interior layout and rig.
