About the Aloa 25

Designed by J. Faroux and built by French manufacturer Aloa Marine beginning in 1972, this 25-footer represents solid European craftsmanship from the early days of fiberglass sailboat production. With its masthead sloop rig and fin keel configuration paired with a transom-hung rudder, the Aloa 25 delivers predictable handling characteristics that made it popular among coastal cruisers and sailing schools. The boat's moderate proportions strike a practical balance for small-boat cruising. Her 8.86-foot beam provides reasonable interior volume while maintaining manageable sail handling, and the 312 square feet of sail area offers adequate power without overwhelming a small crew. The substantial ballast-to-displacement ratio contributes to solid stability, while the comfortable motion suggested by her design ratios makes her well-suited for coastal passages and protected water sailing. Built with traditional fiberglass construction methods, these boats have proven durable over their five-decade production history. The design emphasizes seaworthiness over pure performance, making it an appealing choice for sailors seeking a reliable, manageable boat for learning or casual coastal cruising. Her French pedigree and straightforward sailing characteristics have earned the Aloa 25 a reputation as a dependable small cruiser.

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
20.74
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
35.2
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
116.96
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
12.85
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
2.28
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. 6.60 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. 768.65 pounds/inch
