The 1978 Westerly Berwick 31 is a timeless British-built cruising yacht renowned for its solid construction, dependable offshore capability, and practical twin-keel design. Built by the respected Westerly Marine Construction yard and designed by legendary naval architect Laurent Giles, the Berwick has earned a reputation among sailors as a safe, stable, and comfortable cruiser capable of handling both coastal adventures and extended offshore passages with confidence.
“First Lady” is a sweet little yacht with plenty of nautical miles still ahead of her. Her unique twin-keel configuration gives her excellent stability and balance in the water, often compared to the smooth and steady motion of a dolphin. This setup not only improves comfort at sea but also allows the yacht to safely dry out upright in tidal waters, making her especially practical for cruising shallow harbors, estuaries, and coastal anchorages.
With a strong fiberglass monohull construction and classic Westerly craftsmanship throughout, the Berwick was built during an era when yachts were known for durability and seaworthiness. Her moderate displacement, solid ballast ratio, and forgiving handling characteristics make her ideal for sailors seeking a reliable cruising yacht with classic charm and proven offshore capability.
Sailing Performance
The Westerly Berwick is designed for comfortable cruising rather than outright racing performance. Under sail, she offers predictable handling, impressive directional stability, and a reassuring motion even in rougher sea conditions. Her masthead sloop rig is simple to manage and well suited for short-handed sailing, couples cruising, or family adventures.
“First Lady” comes with a good inventory of sails and is ready to set off immediately. With just a few finishing touches and personal upgrades, she has the potential to become a capable long-distance cruiser suitable for serious offshore passages or even circumnavigation.
Her twin-keel arrangement provides several practical advantages, including:
- Excellent stability underway
- Ability to dry out upright on tidal flats
- Access to shallower cruising grounds
- Reduced draft for coastal navigation
- Comfortable handling in varying sea conditions
