About the Aloa 34

With limited documentation available, the Aloa 34 represents one of the more enigmatic designs in the 34-foot sailboat category. This French-built yacht emerged from the Aloa shipyard, which was known for producing solid fiberglass cruising sailboats during the 1970s and 1980s. Based on typical Aloa construction philosophy, this boat likely features robust fiberglass construction with practical accommodations suited for coastal cruising and light offshore passages. French builders of this era typically emphasized seaworthiness and comfort over pure performance, suggesting the Aloa 34 would appeal to cruising sailors who prioritize reliability and livability. The limited availability of detailed specifications may reflect the boat's relatively small production run or its primary distribution in European markets. This scarcity can make research challenging for potential buyers, but also means existing examples may represent unique opportunities for sailors seeking something off the beaten path. Given Aloa's general design philosophy, prospective owners should expect a traditionally-rigged cruiser with adequate performance for coastal exploration and extended cruising, though thorough inspection would be essential given the age of most examples and the challenges of sourcing specific parts or documentation.

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
13.95
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
21.38
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
2.09
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. 6.61
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. 941.88
