About the Wavelength 30

Designed as a capable and accessible cruiser-racer, the Wavelength 30 offers a compelling option for sailors seeking a versatile 30-foot monohull that performs well across a range of conditions. Built with a practical balance between performance and comfort, this boat appeals to those interested in coastal cruising, club racing, and weekend passages where dependability and ease of handling are valued qualities. While detailed specifications for the Wavelength 30 are limited in available documentation, the boat has earned a modest following among sailors who appreciate its manageable size and sea-kindly behavior. A 30-foot hull sits in a sweet spot for shorthanded sailing, offering enough space for a small crew or overnight accommodations without the complexity of a larger vessel. For buyers researching the Wavelength 30, connecting with current owners and class associations is strongly recommended, as firsthand accounts often reveal the nuances of a boat's true character. Used examples can represent strong value for sailors entering keelboat ownership or looking to downsize without sacrificing the pleasure of genuine open-water sailing.

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
120
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
44.29
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
