About the Javelin 14 Fox Fk

Designed by legendary British naval architect Uffa Fox and first launched in 1960, this compact 14-footer represents a fascinating piece of small boat history. O'Day Corporation brought Fox's innovative design to American waters, creating a diminutive yacht that punches well above its weight class. The Javelin 14's most distinctive feature is its sophisticated fin keel with bulb configuration, unusual for a boat of this size and era. This advanced underbody design, combined with 195 pounds of ballast in a 495-pound package, creates impressive stability and sailing performance. The fractional sloop rig carries 125 square feet of sail area, delivering spirited performance with a theoretical hull speed approaching 5 knots. Fox's design philosophy emphasized seaworthiness regardless of size, and the Javelin 14 reflects this approach. The fiberglass construction ensures durability, while the boat's proportions suggest it's capable of more challenging conditions than typical dinghies. With comfortable ratios indicating good motion characteristics and reasonable capsize resistance, this boat suits experienced small boat sailors seeking coastal adventures, sailing instruction, or spirited day sailing. The Javelin 14 offers a unique opportunity to experience Uffa Fox's design genius in an accessible, trailerable package.

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
32.01
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
39.39
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
96.74
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
5.65
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
2.87
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. 4.86 kn
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. 266.82 pounds/inch
