About the Trotter Pandora

Designed as a compact and versatile cruising sailboat, the Trotter Pandora represents a practical choice for sailors seeking a manageable vessel suited to coastal and inland waters. Built with the recreational sailor in mind, the Pandora carries the hallmarks of thoughtful small-boat design, balancing ease of handling with enough capability to make day sailing and weekend cruising genuinely enjoyable experiences. While detailed specifications for the Trotter Pandora are limited in available records, the boat has attracted a following among sailors who appreciate its approachable size and relatively straightforward systems. Boats of this character tend to reward owners who enjoy hands-on seamanship without the complexity and maintenance demands of larger offshore cruisers. For those researching a first keelboat or a secondary vessel for relaxed sailing, the Pandora merits consideration. Its design lineage suggests a boat that prioritizes comfort and stability in protected and semi-exposed conditions rather than offshore passages or competitive racing. Prospective buyers would be well advised to seek out owner communities and inspect available examples carefully, as firsthand accounts from current owners remain the most valuable resource when formal documentation is sparse.

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
15.5
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
15.58
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
2.03
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. 5.64
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. 436.24
