About the Andromeda 48

With limited specifications available, the Andromeda 48 represents one of those intriguing sailboats that requires deeper investigation from prospective buyers. This 48-foot vessel falls into the mid-size cruising category, positioning itself as a potential bluewater cruiser capable of extended offshore passages while remaining manageable for coastal exploration. Based on typical designs from this era and size range, the Andromeda 48 likely features a moderate displacement hull optimized for comfortable passage-making rather than racing performance. The length suggests accommodation for extended cruising, with sufficient space below for provisioning and living aboard during long voyages. Sailboats in this class traditionally appeal to serious cruisers seeking a balance between comfort and seaworthiness. The 48-foot length typically provides enough stability and interior volume for couples or small families planning extensive coastal cruising or ocean crossings, while remaining within the realm of what experienced sailors can handle shorthanded. Given the scarcity of readily available information, potential buyers should conduct thorough research into the boat's construction methods, sail plan configuration, and specific design lineage. Professional surveys become particularly important when considering vessels with limited documentation, ensuring any purchase decisions are based on the actual condition and capabilities of the individual boat.

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
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
39.34
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
1.73
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
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. 2.0
