Role	Reference compendium

Sailboat Data Sailboat Data is a compiled reference corpus used by builders, designers, skippers, and historians to compare hull lines, rig plans, displacement, and sail areas across classes and eras. It aggregates measurements, provenance, and performance parameters drawn from archival registries, yacht clubs, and class associations to support restoration, racing preparation, and archival scholarship.

Overview

Sailboat Data aggregates technical entries from sources such as the Lloyd's Register, the International Sailing Federation, the Royal Yachting Association, and the American Bureau of Shipping, while cross-referencing archival material from the National Maritime Museum, the Mystic Seaport Museum, and the National Archives. The dataset covers designs by celebrated naval architects including Olin Stephens, William Fife III, Thomas E. Colvin, and John Alden, and builders such as Sparkman & Stephens, Beneteau, Nautor's Swan, and Holland Jachtbouw. Users consult entries during events like the America's Cup, the Fastnet Race, the Sydney to Hobart Yacht Race, and the Rolex Fastnet Race for benchmarking and historical comparison.

Design and Construction

Entries document hull form parameters first formalized in treatises by Olin Stephens and in pattern books held at the National Maritime Museum. Data fields include LOA, LWL, beam, draft, displacement, ballast, prismatic coefficient, and sailplan dimensions derived from original lofting drawings by firms like Sparkman & Stephens, Herreshoff Manufacturing Company, and William Fife & Son. Construction notes cite materials such as carvel oak frames used by James Cook era shipwrights, cold-molded mahogany techniques developed by Clifford Ashley, and modern composites produced by facilities like Gurit and Hexcel. Keel and rudder descriptions reference evolution seen in classes governed by the International Yacht Racing Union and contemporary practices influenced by naval architecture curricula at MIT School of Engineering and University of Southampton.

Performance and Handling

Performance metrics include polar diagrams, VPP outputs, and handicapping numbers from systems such as ORC, IRC, and PHRF, with historical comparisons to racing programs in the America's Cup and coastal regattas run by the Royal Yacht Squadron. Handling notes draw on sea trials reported in journals like Yachting World and technical papers presented at conferences organized by the Royal Institution of Naval Architects and the Society of Naval Architects and Marine Engineers. Specific case studies reference sail plans optimized by designers like Gerry Douglas and Bruce Farr, and trim strategies used during events such as the Transpacific Yacht Race and the Clipper Round the World Yacht Race.

Equipment and Systems

Catalogued systems include standing and running rigging specifications by suppliers such as Harken, Ronstan, and Schaefer Marine, and deck hardware layouts used by builders like Beneteau and Jeanneau. Propulsion and auxiliary systems cite engine installations from Yanmar, Volvo Penta, and Perkins, electrical systems referencing battery technology from Victron Energy, and navigation suites integrating electronics by Raymarine, Garmin, and B&G. Interior fitout notes mention joinery traditions from the Herreshoff Manufacturing Company and modern modular systems by yards such as Nautor's Swan and Hallberg-Rassy.

Safety and Regulations

Safety entries cross-reference maritime conventions and regulatory frameworks including the International Convention for the Safety of Life at Sea, salvaging standards discussed at the International Maritime Organization, and racing safety protocols from the World Sailing Offshore Special Regulations. Lifesaving equipment, stability criteria, and loadline considerations are informed by testing standards from Det Norske Veritas and Lloyd's Register, with incident analyses referencing investigations like those recorded by the Marine Accident Investigation Branch and search-and-rescue case studies from the United States Coast Guard.

Notable Models and Manufacturers

The compendium highlights landmark designs and yards, including classic models from Herreshoff Manufacturing Company, production series by Beneteau, performance cruisers from Nautor's Swan, and custom builds by Wally Yachts and Holland Jachtbouw. Famous classes and models cited include entries relating to J/Boats designs, Catalina Yachts coastal cruisers, and racing designs by Bruce Farr and Olin Stephens. Restoration projects reference conservation work at institutions such as the Mystic Seaport Museum and collaborations with heritage shipwrights trained under apprenticeships tied to the National Maritime Museum.
