Halcyon sailboats: a Buchanan design range, one Hertfordshire builder
"Halcyon" isn't the name of a boatbuilder -- it's a range name for a family of British GRP cruising yachts, all drawn by naval architect Alan Buchanan and built, in every documented case, by a single yard: Offshore Yachts Ltd of Royston, Hertfordshire. Three models carry the name in this catalog -- the Halcyon 23, the Halcyon 27, and the Halcyon Clipper, listed here as the Clipper 26 -- and all three trace back to the same run of Buchanan design work spanning the late 1960s and early 1970s.
Origins and ownership
Before there was a Halcyon, there was the Crystal: a 22ft 6in GRP sloop Buchanan drew at the start of the 1960s, its hulls produced by French Bros. and by Seamaster and then fitted out by Stebbings. Production later transferred to Offshore Yachts of Royston, Hertfordshire, where the modified boat was renamed the Halcyon 23 and built in large numbers -- the point at which the Halcyon range, as such, begins. The National Maritime Museum Cornwall holds an archive of Buchanan's yacht plans, still being catalogued, which dates the Halcyon 23 to 1969, a 27-foot boat listed simply as "Halcyon" to 1968 (part-catalogued), and a separate "Halcyon Clipper" at 26 feet to 1971. The same archive also catalogs an unrelated Buchanan plan from the period, a 27-foot "Diamond Mk II" dated 1964 -- a reminder that Buchanan's design output extended well past the handful of boats that ended up under the Halcyon name.
Buchanan himself was a British naval architect and sailor credited with designing the first glassfibre yacht built in Europe. Originally based in Burnham-on-Crouch, he moved his design office to Jersey in the 1960s and was credited over his career with upwards of 2,400 boats; in 1979 he received the medal of the Royal Institution of Naval Architects' Small Craft Group. Classic yacht broker Barney Sandeman, of Sandeman Yacht Company, has argued that Buchanan's designs were at their best before the racing box rules of the late 1960s "spoiled aesthetics and sea-keeping qualities" -- a period that brackets most of the design work behind the Halcyon range itself.
Construction through the eras
Offshore Yachts built more than the 23. Buchanan separately drew the Halcyon 27 as a Folkboat-derived design, a size class he also produced, for the unrelated yard Thames Marine, as the Diamond 27. Of the two, the Halcyon 27 was by far the more popular, with large numbers built before production ceased in 1975; its hull is fibreglass, built on a long keel. Several Services sailing clubs bought Halcyon 27s for sail training.
Lines and generations
The Halcyon 23 is the range's direct descendant of the Crystal-class hull described above. The Halcyon 27 anchors the range as its most-built model. A third model, catalogued here as the Clipper 26, is the Halcyon Clipper -- the museum's plans archive lists it at 26 feet in 1971, but period owner-registration records complicate that figure: a 1972 boat, Dolphina, is recorded against a "Halcyon Clipper 27" design, while a second 1972 boat, Sea Samurai, is recorded simply as "Halcyon Clipper." The boat appears in the historical record at both lengths.
Who Halcyon is for
A buyer drawn to a Halcyon is buying into one Hertfordshire yard's Buchanan-designed GRP cruisers from a narrow window in the late 1960s and early 1970s -- the 23 and 27 built in large numbers, the Clipper a scarcer third model -- rather than a brand with a long production run or a wide model spread to compare across decades.
