JOHN G. ALDEN 121 FT 3-MASTED GAFF SCHOONER 2021

It seems hard to believe it took so long for this magnificent vessel’s preliminary drawings to be given form. Perhaps the most authentic expression of John G. Alden’s highly successful fusion of the American fishing schooner as pleasure yacht, her 1927 design date parallels his most successful period in fast cruiser design, when his MALABARs ruled the waves. After gathering dust at the John G. Alden office for almost 90 years, along came an individual with the knowledgeable passion and vision to bring Design No. 347 to life as WOLFHOUND. All executed by the best possible people, including naval architect Niels C. Helleberg who began his Alden design career working beside the man who had originally drawn her lines. For her hull builder, Graafship, it’s the first time they’ve built a genuinely new classic schooner instead of a replica, and she was a labour of love for her finishing craftsmen. Since completion in 2021, WOLFHOUND already has two Atlantic crossings under her belt and a period of extensive Baltic cruising, all crewed by family and friends, and is very well-proven. Vindication of John Alden’s minimally crewed dream yacht for exploration adventures beyond the horizon: WOLFHOUND’s brave, wholesome appearance - very different from the replicas built for the classic regatta circuit - shouts this.

JOHN G. ALDEN DESIGN NO. 347
ORIGINAL DESIGN DATE: 1927

"His great confidence at sea and his skill as a deep-water helmsman and ocean-racing tactician were notable and were clearly grounded in experience. Combined with his eye for balance and shape, his experience gave him a unique ability to find the geometry that worked with the sea." Olin J. Stephens on John G. Alden in 'John G. Alden and his Yacht Designs' (1983)

"One of the most impressive Alden designs, from the standpoint of beauty as well as size... In her profile and the shape of her sections, her Gloucesterfisherman ancestry is discernible." Robert W. Carrick & Richard Henderson in 'John G. Alden and his Yacht Designs' (1983)

Alden design #347's lines were drawn for John G. Alden as the client by stalwart of the Alden office Clifford P. Swaine (1902-1992, worked with John G. Alden c. 1922-1979), a highly talented naval architect who could easily have branched out on his own, but stayed with Alden his whole working life.

With no client involvement, we can easily speculate that this was Alden's dream yacht for adventures well beyond the horizon. But a client never materialised - perhaps because of the Great Depression - and the drawings for this magnificent vessel, infused with American fishing schooner genes, gathered dust until the incredibly complete John G. Alden archive became part of the Hart Collection at Massachusetts Institute of Technology when the Alden business closed in 2008, one year short of its centenary.

The naval architecture career of Niels C. Helleberg (1940-2014, worked with John G. Alden 1971-2008) overlapped with Clifford Swaine. So it couldn't have been more poignant and appropriate that Helleberg would undertake the work to prepare the 20th Century drawings for a 21st Century build.

Design #347 is a preliminary design that includes the final lines, two different rig and sail plans (a 2-masted and a 3-masted version), as well as a 3- masted accommodation plan. The 3-masted sail plan is by far the more spectacular design of the two. However, no detailed construction drawings were produced for this design in 1927. For this reason some of the details in the implementation were inferred from other Alden designs from the same time period.

Helleberg was instrumental in creating this design in the the spirit of the 1920s Alden steel schooners. A number of details and specifications from the final Design #284 of STARLING (launched in 1926), including the 530 mm frame spacing, were used as a guide to finalise the #347 construction drawings faithfully in the spirit of John G. Alden.

Although the preliminary design indicated that she would be built in wood, the final design is implemented in welded steel. The implementation in steel is consistent with the materials Alden used for most of his larger schooners from the era. However, to honor the heritage of the preliminary line drawings, the hull lines for the steel construction of WOLFHOUND retain what would have been the wood hull's moulded stem, the rabbet line, and the recessed bulwarks normally only seen on wooden hulls. From a distance she looks like a wood construction.

WOLFHOUND is a very simple and straight forward yacht. John Alden wrote in his designer's notes about the intended small crew and general approach: “A three-masted schooner of this length is handled by a total crew of five men for coast wise work and seven when offshore, including the cook. There is no reason why this boat should require more if fittings are kept simple and plain. Of course the cost of construction is reduced to a minimum.” The theme, or philosophy, for the WOLFHOUND project from 2012 and onward would be AUTHENTICITY and EXTREME SIMPLICITY in the spirit of
John Alden’s general philosophy expressed in his designer's comments.

GRAAFSHIP YARD NO. 455
- To Lloyd's A-1 specifications with a Lloyd's hull certificate

Small to medium sized Dutch steel shipbuilders have long been held in high renown for a no-nonsense approach to the production of beautifully constructed, perfectly fair yacht hulls - often eventually carrying the name of the more famous yacht finisher they were built for. For over 20 years

Graafship of Dordrecht, formerly Van der Graaf lasonderneming B.V. of Hardinxveld-Giessendam, have gained a particular reputation for classic schooner creations and re-creations, including ELEONORA (2000), NAEMA (2006), ATLANTIC (2010), INGOMAR (2012), and WOLFHOUND (hull completed 2016). Laid down in 2013, WOLFOUND was barged to Enhuizen in 2016 for the fit out by Opus Five Ltd. and André ten Broeke, with the major deck structures built by Absolute (Portugal). The rig was built by SRF hipbuilding in Harlingen, and dressed by MdeGroot of Staveren. WOLFHOUND was commissioned in 2021.

WOLFHOUND’s interior is built in a high quality authentic 1920’s panelled style. All the sipo mahogany wood for the entire yacht came from one single log and is treated with hard wax. The sole is white oak, oil treated. The white surfaces are painted with Epifanes 'Wolfhound White' satin finish. Most of it is hand painted for authenticity. Hardware is period style and the saloon furniture was designed in 1924 by Marcel Brewer, and 1928 by Le Corbusier.
