About the Offshore 27 Newell

Designed by George T. Newell and built by Hong Kong's respected Cheoy Lee Shipyard starting in 1965, this compact cruiser represents classic mid-1960s offshore sailing philosophy. The fiberglass construction features a traditional long keel configuration that prioritizes seaworthiness and directional stability over pure performance. With her masthead sloop rig and generous displacement of 6,900 pounds on a 27-foot hull, this boat carries the substantial feel of larger vessels. The long keel design, while sacrificing some maneuverability in tight quarters, provides excellent tracking ability and contributes to a reassuring motion in seaway conditions. Her comfort ratio of 33.37 indicates a relatively stiff, stable platform that resists excessive rolling. The design suits coastal cruising and extended offshore passages for experienced sailors who value traditional sailing characteristics over speed. Her capsize screening formula of 1.61 falls within acceptable parameters for offshore work, though modern safety standards would recommend additional considerations for serious blue-water voyaging. Cheoy Lee's reputation for solid construction during this era means well-maintained examples often represent excellent value for sailors seeking an affordable entry into serious cruising. The boat's moderate sail area and substantial ballast create a forgiving sailing experience, making it suitable for couples or small crews planning extended adventures.

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
14.17
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
39.13
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
467.3
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
33.37
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
1.61
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. 5.80 kn
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
0.73
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. 513.86 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 14.16
