About the Creekmore 20

Designed by Lee Creekmore and first launched in 1979, this compact 20-footer represents a thoughtful approach to small boat cruising with surprising accommodations for its size. The fiberglass construction combined with a keel/centerboard configuration gives owners the versatility to explore both deeper waters and shallow gunkholes that would challenge fixed-keel boats of similar length. With a generous beam of 8.20 feet and substantial displacement of 2,750 pounds, the Creekmore 20 offers impressive stability and interior volume for weekend coastal cruising. The masthead sloop rig provides straightforward sail handling, while the moderate sail area keeps the boat manageable for small crews or single-handed sailing. Her comfort ratio of 13.77 suggests a motion that favors stability over speed, making her well-suited for leisurely coastal exploration rather than competitive racing. The hull's design emphasizes seaworthiness over pure performance, with a capsize screening value that indicates reasonable offshore capability for experienced sailors, though her primary strengths shine in protected waters and coastal day sailing. Her moderate hull speed reflects the designer's priority on comfort and accommodation over racing performance, creating a boat that rewards careful seamanship with reliable, predictable sailing characteristics.

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
18.22
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
212.27
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
13.77
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
2.34
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. 5.68 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
2.7
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. 525.93 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. 18.22
