About the Jaguar 27 Sailboat

Designed by the collaborative team of Frank Butler and Bob Finch, this British-built sailboat emerged from Eric Birch Yachts in 1971 as a well-balanced coastal cruiser. With its masthead sloop rig and moderate fin keel configuration, the Jaguar 27 strikes an appealing balance between performance and comfort for sailors seeking weekend adventures and extended coastal passages. The boat's proportions reveal thoughtful design decisions, featuring a waterline length of 21.75 feet that contributes to a respectable hull speed of 6.25 knots. The substantial displacement of 6,850 pounds, combined with 2,700 pounds of ballast, creates a stable platform that inspires confidence in varied conditions. This weight distribution results in a comfort ratio of 24.88, indicating good seaworthiness for coastal and near-offshore sailing. The fiberglass construction typical of early 1970s British boatbuilding provides durability, while the sail area to displacement ratio of 13.62 suggests moderate sailing performance with manageable sail handling. The capsize screening formula of 1.87 falls within acceptable ranges for coastal cruising, making this an attractive option for sailors prioritizing safety and comfort over pure speed. The Jaguar 27 represents solid British yacht design from an era when builders emphasized seaworthiness and traditional sailing qualities.
