The Cheoy Lee Flying Buffalo 36/Offshore 36 represents a mid-20th-century evolution in fiberglass sailing yachts: lighter than traditional full-keel cruisers, faster than heavy displacement boats of the era, and versatile for a range of sailing conditions. Its combination of solid construction, balanced performance, and classic lines make it a classic blue water cruiser and club racer, celebrated in both historical sailing circles and contemporary restorations.
