About the Lindenberg 28

With limited documentation available, the Lindenberg 28 represents one of those intriguing sailboats that has left only faint traces in maritime records. This 28-foot vessel appears to have been produced in small numbers, making it a relatively rare find in today's used boat market. Based on its size class and era, the Lindenberg 28 would have been designed primarily for coastal cruising and weekend sailing, offering a manageable platform for small crews or couples seeking adventure close to shore. Boats of this length typically strike a balance between seaworthiness and ease of handling, making them suitable for sailors transitioning from smaller dinghies to more substantial cruising vessels. The scarcity of detailed specifications and performance data suggests this model may have had limited production runs or regional distribution. For prospective buyers, this rarity could present both opportunities and challenges—potentially offering a unique vessel at an attractive price point, while also meaning that parts, documentation, and expert knowledge may be harder to source. Anyone considering a Lindenberg 28 should conduct thorough surveys and research, as the limited available information makes careful inspection even more critical than usual.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
117
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
25.02
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
12.08
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
2.4
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. 6.62
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
4.86
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. 829.6
