About the Us 29

A relatively obscure entry in the American production sailboat market, the US 29 is a compact sloop that reflects the practical, accessible design philosophy common to club racing and recreational sailing of its era. Built by United States Sailing Corporation, this boat was aimed at sailors looking for an affordable, manageable vessel suitable for day sailing and short coastal passages. With its modest size, the US 29 lends itself well to inland lakes, protected bays, and near-shore coastal sailing where simplicity and ease of handling are valued over offshore capability. The design prioritizes approachability, making it a reasonable choice for intermediate sailors looking to develop their skills without the complexity of a larger cruiser. While the US 29 never achieved the widespread recognition of more celebrated one-design classes, it has maintained a quiet following among budget-conscious sailors who appreciate its straightforward construction and low maintenance demands. Used examples occasionally surface at attractive price points, making the boat an intriguing option for those entering sailboat ownership. Prospective buyers should prioritize a thorough survey, as aging examples may require attention to rigging and hull integrity.

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
17.33
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
19.86
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
2.15
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. 6.34
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
1.96
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. 821.12
