The Westerly Berwick 31 is a 31foot coastal cruiser built around a hull shared with three other Westerly models, distinguished by its twin bilge keels and a deckstepped masthead sloop rig. Conceived by Laurent Giles and Partners for Westerly Marine Construction Ltd in the early 1970s, it trades the finkeel Longbow's profile for a configuration that can take the ground upright in tidal harbors — a defining trait for a boat aimed at shallowwater cruising grounds.

Westerly Berwick 31 Buyer's Guide

The Westerly Berwick 31 on the used market is a 31-foot twin-keel coastal cruiser from Westerly Marine Construction Ltd, designed by Laurent Giles and Partners, with production starting in 1973. Its defining used-market trait is the bilge-keel hull that dries out upright in tidal harbors, shared with the Centaur 26's configuration philosophy but in a larger, three-cabin package than the fin-keel Longbow alternative.

Layouts on the Used Market

Every Berwick 31 carries the same core hull introduced in the early 1970s, with a raised coachroof, high freeboard, and wide 2.9 m beam giving standing headroom and a three-cabin plan for six. The forward V-berth, convertible saloon settees, and quarter berth behind the starboard nav station are consistent; the galley is always to port at the companionway foot. A large aft cockpit with tiller and wide side decks is standard. The original Volvo MD2B diesel sits in a roomy compartment reached from the cockpit hatch and saloon — a real plus when comparing against tighter engine bays in cross-shopped marques.

Equipment and Common Upgrades

Brokers' listings commonly show heating, AIS, autopilot, and chartplotter already fitted, reflecting the boat's use as a settled coastal cruiser. Inverters and life rafts are often seen as well. Less commonly, buyers will find a bimini or dodger as an owner upgrade. For a shopping shortlist, the meaningful clusters are power and energy — heating and inverter support livable shoulder-season use — and navigation and control, where AIS, chartplotter, and autopilot together reduce short-handed workload on tidal passages. Canvas such as a dodger remains a sporadic owner addition rather than a default.

What to Inspect

The twin cast-iron keels with internal lead ballast are bolted to the hull on stainless steel fastenings, so check the keel bolts and surrounding sealant for any sign of weeping where the boat has taken the ground bolted to the hull with stainless steel bolts. The skeg-hung rudder is foam-cored fiberglass on a stainless stock; inspect the rudder skin for hairline cracks that could let water saturate the core and corrode the stock. The deck is balsa-cored in areas for stiffness, so test around deck fittings and winches for softness that would signal water ingress. The solid below-waterline hull has no core, but the original MD2B is raw-water cooled on many survivors, and some owners have replaced it — confirm cooling type and running hours.

Availability and Buyer's Takeaway

Berwicks appear regularly in the United Kingdom, Ireland, Germany, Türkiye, and Jersey. For a buyer, the practical checklist is: confirm keel-bolt sealant integrity, probe the balsa deck for soft spots, examine the rudder for core saturation, verify engine cooling and access, and note tankage — 76 L fuel and 114 L water — as limiting for long passages. A bilge-keel Berwick rewards the tidal cruiser with drying capability and a stiff, roomy hull at modest ambitions.
