About the Kramer 24

Finding detailed information about the Kramer 24 proves challenging, as this sailboat remains relatively obscure in sailing circles with limited documentation available through typical marine industry channels. What can be inferred from the sparse data suggests this was likely a smaller production or semi-custom design from an era when many boatbuilders were experimenting with affordable cruising designs. Based on the 24-foot length, this vessel would fall squarely into the trailerable cruiser category, making it appealing to sailors seeking coastal adventures without marina slip commitments. Boats of this size typically offer a practical balance between manageable single-handed sailing and basic overnight accommodations for small crews. Without extensive specification details, potential buyers should approach any Kramer 24 opportunity with thorough hands-on inspection, paying particular attention to construction quality, rigging condition, and overall maintenance history. The scarcity of available information also means finding replacement parts or technical support could present challenges. For sailors drawn to unique or lesser-known designs, the Kramer 24 might represent an intriguing project boat opportunity, though practical considerations around parts availability and resale value should factor heavily into any purchasing decision.

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
224
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
20.9
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
17.52
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
1.94
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. 5.69
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
2.75
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. 450.21
