About the Javelin 30 Parker Sailboat

Designed by Fred R. Parker and built by Marine Construction Ltd. in the UK starting in 1971, this 30-foot sailboat represents solid British craftsmanship from the early days of fiberglass construction. The Javelin 30 features a classic fin keel with rudder on skeg configuration, providing good directional stability while maintaining respectable performance characteristics. With a displacement of 6,720 pounds and ballast of 3,220 pounds, this masthead sloop offers a reassuring feel underfoot for coastal cruising and short offshore passages. The moderate comfort ratio of 22.66 suggests a boat that balances seaworthiness with reasonable motion in a seaway, while the capsize screening formula of 1.91 indicates good stability for her size class. The sail area to displacement ratio of 12.48 points to moderate performance potential, making this an ideal choice for cruising sailors who value steady progress over racing speeds. Her 5-foot draft provides access to many harbors while offering sufficient lateral resistance for windward work. The hull's proportions, with a 22-foot waterline length generating a theoretical hull speed of 6.29 knots, create a well-balanced platform suitable for weekend coastal adventures and extended cruising along protected waters.
