Designed as a compact and capable sailboat, the Pyramid 660 is a small keelboat that appeals to sailors looking for an accessible entry point into keel boat sailing without sacrificing the fundamentals of good on-water performance. While detailed specification data remains limited, the 660's sizing suggests it is well suited to sheltered coastal waters, day sailing, and introductory racing, making it a practical choice for those building their skills or seeking a manageable weekend boat.
The Pyramid 660's modest dimensions point to a design philosophy centered on simplicity and ease of handling, qualities that make it attractive to single-handed sailors or small crews. Its keeled configuration offers the stability advantage that distinguishes it from dinghy sailing, providing a more forgiving platform in varied conditions. Boats of this class and character are often found in club racing fleets and calm estuary environments, where their nimble nature can be fully appreciated.
For buyers researching a first keelboat or a low-maintenance coastal cruiser, the Pyramid 660 represents a pragmatic and approachable option worth investigating further through owner communities and local dealers.
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).
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
35.72
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
6.02
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
2.62
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.
5.7
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
8.08
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.
