Designed by the renowned Jack Laurent Giles and built by Westerly Marine from 1980 to 1984, this distinctive twin-keeled cruiser represents British yacht building at its most practical. With only 42 hulls produced during its four-year run, the Vulcan 34 has become a sought-after example of thoughtful coastal cruising design. The twin-keel configuration stands as this yacht's defining characteristic, allowing access to shallow harbors and the ability to dry out safely on beaches or in tidal waters. This feature makes her particularly well-suited for exploring the challenging tidal ranges and shallow anchorages common around British and European coasts. The substantial 6,971-pound ballast provides excellent stability despite the unconventional keel arrangement. With a comfort ratio of 30.1 and capsize screening formula of 1.88, she strikes an ideal balance between seaworthiness and livability for extended coastal cruising. The masthead sloop rig with 570 square feet of sail area delivers respectable performance while remaining manageable for couples or small crews. Her fiberglass construction ensures durability, while the generous 11.75-foot beam maximizes interior volume. This yacht excels as a comfortable coastal cruiser for those who value the flexibility of twin keels over ultimate sailing performance.
