Hand Laid in the USA
Workers at Pacific Seacraft laminate these hulls by hand, using vinylester resin and layers of biaxial fiberglass laid at 45- and 90-degree axes for enhanced multidirectional strength. The decks are cored with balsa wood except for those areas where fasteners pierce through or fixtures are mounted; those spots are cored with either marine plywood, high-density foam, or solid fiberglass. The two-tone deck is accomplished by masking off the nonskid areas in the mold prior to gelcoat application. This yields a very durable surface.

Cost of Miscalculating Hatteras
At the U.S. Sailboat Show in Annapolis last fall, I paused at the newly launched $2.5-million Gunboat 55, Rainmaker, felt the hole in my pocket and moved on. I have always had a weakness for hedonistic follies, but to launch a go-fast carbon-fiber condo into a North Atlantic gale isn't one of them.
Rethinking Sailboat Structure
When it comes to describing a sailboats most valuable attribute, its surprising how varied opinions can be. Staying afloat should be our first priority, and although you seldom read or hear much about it at boat shows, the structural elements that hold a sailboat together are an all-important consideration.
Standards: Costly Hurdles or Vital Guidelines?
The ISO 12215 standard gives designers and builders a detailed baseline for scan'tlings and specific guidance regarding material selection, workshop practices and structural details pertaining to hulls, decks, rudders and rigging for mono and multihulls. These scan'tling guidelines relate to specific skin pressures on the hull and stresses and strains that if not appropriately addressed can affect delamination and lead to structural failures. The codes are a complex amalgamation of data, but the University of Southamptons Wolfson Unit has recently developed a software program called HullScan't that makes ISO compliance for builders and designers easier to work with.
Dissecting the CSY 37
Designed by Peter Schmitt, the CSY 37 is the mid-sized boat in the CSY line. Eighty-seven of these raised-deck cutters were built, primarily for the Caribbean bareboat charter trade. Schmitt has combined some features most often found in traditional boats-the oval stem, raised deck, and semi-clipper bow-with a relatively modern underbody featuring a fairly long fin keel and a skeg-mounted rudder. On paper, the boat looks pretty good. In person, she is rather tubby and high-sided, but that tubbiness means added buoyancy-not such a bad thing to have in a blow.
Heavy-duty Hull Gets High Praise
With more than three decades of hard use behind it-first in the charter trade and later in private ownership-the CSY 37 has very few secrets. All its warts are well exposed; as are its strengths. About two-dozen current and former owners responded to our survey, and we saw many consistencies in their comments. Most owners praised the boats rugged construction and stability and lamented its upwind performance. On the whole, the boat delivered what they expected of a cruising boat: namely a boat that would get them (and a fair amount of gear and provisions) safely and comfortably to their destination. Nearly all of the respondents had the owners version or B layout, and praised its livability. The following summaries and comments are representative of the majority of responses we collected.
Express 37 Nails Performance
Following graduation from California State Polytechnic University, naval architect Carl Schumacher spent four years working as an apprentice with Gary Mull before opening his own shop in Alameda, California, in 1977. He has since designed 37 boats ranging in size from one tonners to 50-foot world cruisers, participated in the design of the front-ruddered Americas Cup boat skippered by Tom Blackaller in the 1987 trials, and most recently designed the Alerion Express boats, which are being constructed at TPI Composites, Inc.
A Herreshoff Legacy Lives On
It took some time for the Stuart Knockabout, an L. Francis Herreshoff design, to take root and finally flourish. The 28-foot day boat first appeared in 1932 as line drawing number 53 in the L. Francis annals, and only one boat was built. In 1933, Ben My Chree (a Galic term of endearment), was launched and wound up nestled away in Casco Bay, Maine, at the island home of owner Willoughby Stuart. With its own small marine railway and boat shed, Ben My Chree remained in the family for nearly 40 years. In the mid-1980s, it was discovered in a Massachusetts boat shed by Bill Harding, a sailor known for his deft hand on the tiller and the builder of the popular Herreshoff 12 replica-affectionately known as the Doughdish. Harding fell for the lines of daysailer he had discovered, and he researched the boats lineage. After getting a feel for what it had to offer under sail, he decided that this was another slice of sailing history that deserved being resurrected.
Craftsmanship is at the Heart of Construction
Modern engineering works well with many older designs. In the Stuart Knockabouts original plans, soft wood planks were mechanically fastened to hardwood frames and the its shoal-draft keel/centerboard was bolted to the keelson. Timber boatbuilding is labor intensive and the time-saving shortcuts found in molded FRP hull and deck construction have a well-proven track record. Add to this the fact that wooden hulls and decks are susceptible to rot, and its clear that Hardings vision of a fiberglass/foam sandwich Stuart Knockabout was a best-of-both-worlds solution rather than a sacrilege. The result of the FRP conversion is a stiffer/stronger, monocoque hull that required less maintenance and is much more immune to the elements.
