About the Boreal 47 2

French shipyard Boréal introduced this aluminum-hulled 47-footer in 2020, designed by Jean-François Delvoye for serious offshore cruising. Built with the demanding conditions of high-latitude sailing in mind, the Boreal 47 2 features robust aluminum construction that can handle ice encounters and remote-water exploration that would challenge fiberglass hults. The boat's cutter rig configuration provides versatile sail handling options for varying wind conditions, while the combination keel and centerboard design offers both stability offshore and shallow-water access to remote anchorages. At nearly 47 feet overall with a displacement of over 30,000 pounds, this is a substantial cruising platform built for extended voyaging rather than weekend sailing. Notable design characteristics include excellent directional stability from the spade rudder configuration and respectable performance under sail despite the cruising-oriented displacement. The comfort ratio of 30.74 indicates a motion that favors seakeeping over speed, while the capsize screening value of 1.86 falls within acceptable parameters for offshore work. Boréal's reputation centers on building expedition-capable yachts for sailors planning arctic passages, circumnavigations, and other ambitious long-distance cruising adventures where reliability and strength matter more than racing performance.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
17.87
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
27.84
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
184.34
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
30.74
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.86
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 8.66 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 2,149.18 pounds/inch
