About the Gannet 40

With limited specifications available, the Gannet 40 remains somewhat enigmatic in the sailing world, yet this scarcity of information often indicates a boat that was either produced in small numbers or represented a specialized design for particular sailing applications. Based on its 40-foot length, this sailboat would typically fall into the category of serious cruising or racing vessels, suggesting capabilities for both coastal and potentially offshore sailing. Boats of this size generally offer a good balance between performance and livability, making them suitable for extended cruising adventures or competitive sailing events. The Gannet name evokes images of these graceful seabirds known for their efficient long-distance flight and precise diving abilities, qualities that would presumably translate into a sailboat designed for purposeful passage-making and responsive handling. Without detailed specifications, potential buyers should focus their research on finding examples of the boat in person or connecting with existing owners who can provide firsthand insights into the vessel's sailing characteristics, build quality, and overall suitability for their intended use. The limited available information makes thorough inspection and sea trials particularly important for anyone considering this model.

Performance Ratios
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).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
81
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
45.52
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
