Construction
Sources
Dimensions/sail area per Chris White Designs' own product page (LOA 57ft, beam 28'4"/28.33ft, draft 3'5" board-up / 7'10" board-down, displacement 26,500lb, main 983 sqft, blade jib 438 sqft, genoa 810 sqft as an alternative headsail, spinnaker 2,300 sqft) -- upwind total computed as main+blade-jib (the smaller, self-tacking working headsail) since no single published total was found. Beam/draft/displacement/sail-area-total independently cross-checked against an aggregator (listingsport.com) that agrees on all four. That same aggregator cites LWL as 57ft, identical to LOA -- consistent with this dataset's other plumb-bow-catamaran entries where a cited LWL exactly matches LOA, and roughly corroborated by Cruising World's review noting a ~12:1 waterline-length-to-(single-hull)-beam slenderness ratio, which is only plausible if LWL is close to the full 57ft. Not an independently re-measured figure. Rig described as 'Solent' by one source and 'cutter' by another (Cruising World); classified as cutter, the closer fit in this dataset's enum, since a Solent rig is a modern cutter variant (twin closely-spaced headstays). Hull is glass/carbon composite (E-glass primary skins with carbon fiber reinforcement in high-stress areas per the designer's own site; a separate review lists 'triaxial E-glass' with Core-Cell/AirLite foam cores, no carbon) over 100% epoxy resin, vacuum-bagged -- classified as grp_fiberglass/epoxy. Standard mast is carbon fiber; aluminum spars offered as an option. Asymmetrical daggerboards. Twin diesel saildrives. Chris White Designs (South Dartmouth, MA, founded 1983) is a naval-architecture studio, not a single-yard builder -- this design has been built by multiple contract yards over the years, notably Alwoplast (Chile) and Aquidneck Custom Composites (USA), also reported as Bongers Marine (South Africa) for some hulls. First hull reported built 2006, though the underlying Atlantic-series design lineage dates to the 1980s-90s. Verified 2026-07-12. [Rudder/tankage/electrical update, 2026-07-16]: Rudder blades are fiberglass composite, high-performance hydrofoil section, on solid TITANIUM rudder stocks in low-friction bushings (integral swim step built into the rudder). Titanium isn't one of this dataset's original three rudder_shaft_material options (stainless_steel/carbon_fiber/aluminum) -- added as a fourth enum value (migration 0018) rather than mis-classified as the nearest metal, since it's a real and meaningfully different premium material choice (corrosion-immune, very high strength-to-weight). Fuel: 2x100gal tanks = 200gal; water: 2x80gal tanks = 160gal.
