About the Grampian 34

Launched in the late 1970s by Grampian Marine, this 34-foot sailboat emerged during an era when Canadian builders were establishing themselves as producers of solid, practical cruising yachts. The Grampian 34 represents the company's commitment to creating affordable boats that prioritized seaworthiness and comfort over racing performance. Built with a traditional full keel design, this vessel offers the stability and tracking ability that appeals to cruising sailors, particularly those planning coastal passages or extended voyaging. The full keel configuration provides excellent directional stability and creates a protected aperture for the propeller and rudder, though at the expense of shallow-water accessibility and quick tacking response. The boat's construction follows Grampian's reputation for sturdy fiberglass work, with adequate interior volume for extended cruising. While not known for exceptional speed, the design emphasizes reliability and comfort at sea. The cockpit and deck layout reflect practical considerations for shorthanded sailing, making it suitable for couples or small crews. Today, the Grampian 34 appeals to budget-conscious sailors seeking a capable cruiser with a proven track record, though prospective buyers should carefully inspect older examples for common issues related to through-hull fittings and aging electrical systems.

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

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
30.2
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
1.75
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. 6.89
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
