About the Akilaria 40

Designed by renowned French naval architect Marc Lombard and built by Mc Tec Shipyard in Tunisia, this performance-oriented sailboat represents modern European sailing design at its finest. The Akilaria 40 entered production in 2007 as a sophisticated blend of racing prowess and coastal cruising capability. With its composite construction and fin keel featuring a bulb design paired with dual rudders, this fractional sloop demonstrates serious sailing credentials. The relatively light displacement of 10,251 pounds combined with generous sail area creates an impressive sail area-to-displacement ratio of 42.08, indicating strong performance potential in light to moderate conditions. The dual rudder configuration enhances control and reduces weather helm, particularly beneficial when sailing at aggressive heel angles. Marc Lombard's design philosophy shines through in the boat's sleek profile and efficient hull shape, achieving a theoretical hull speed of 8.47 knots. The deep 9.84-foot draft and substantial ballast ratio provide excellent stability for offshore passages, while the low comfort ratio of 11.03 reflects the boat's performance-first orientation rather than traditional cruising priorities. This sailboat appeals most to experienced sailors seeking spirited coastal cruising with occasional offshore capability, or those interested in club racing with comfortable accommodations for extended sailing adventures.

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
 42.08
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
 36.56
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
 71.72
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
 11.03
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
 2.72
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. 8.47 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. 2,103.17 pounds/inch
