The Oceanquest 35 emerged from the board of Edward George Dubois in the early nineties, built by the British yard Westerly Yacht Construction. Her fibreglass hull and deck demand minimal seasonal upkeep, and the design blends space with seakeeping in a package that suits coastal cruisers and those heading further afield.

Design and Construction

The interior revolves around a two-cabin, four-berth layout with a saloon that offers above-average headroom. Teak joinery prevails, the wood’s natural oils making it water-repellent without heavy varnish work. A galley backed by 270 litres of fresh water and a separate head with an 80-litre holding tank give genuine cruising autonomy. Below the waterline, a straightforward fiberglass structure keeps maintenance undemanding.

Rig and Sail Plan

A masthead rig was chosen for the Oceanquest 35, a setup that carries sail area lower and produces less heeling moment than a fractional alternative. This translates into a forgiving feel when the breeze builds, a trait that short-handed crews appreciate.

Keel Configurations

Westerly offered the boat with both bilge-keel and fin-keel options. The twin bilge plates let the vessel take the ground upright, a prized ability for those exploring drying harbours and tidal creeks; draft sits around 1.20–1.30 metres. The deeper fin keel, at roughly 1.37–1.47 metres, sharpens manoeuvrability at the cost of slightly less directional stability than a long-keeled hull.

Underway: Performance and Feel

The numbers place the Oceanquest 35 among heavy cruisers. A displacement-length ratio of 319 points to a hull that favours an easy motion over abrupt acceleration. The Motion Comfort Ratio of 25.9 sits just under the category average for similar designs, a touch firmer than most peers rather than plusher. With a sail-area/displacement ratio of 14.4, the boat remains firmly in cruiser territory, rewarding prudent canvas choices. A Volvo Penta MD2030 diesel pushes her to a cruise speed around 6 knots and a top whack of 7 knots, while the shaft drive promises lower long-term maintenance than a saildrive.

Maintenance Considerations

An underwater profile of approximately 30 square metres simplifies estimating antifouling paint. Running rigging guides specify 14 mm sheets and a 27-metre mainsheet when replacement time arrives. Beyond these routine items, the Oceanquest 35 has proved a straightforward vessel to keep in commission.

The Verdict

The Westerly Oceanquest 35 is a comfortable, well-mannered cruiser whose bilge-keel option brings a rare degree of versatility to the 35-foot category. She will not set pulses racing in a drifting match, but her seagoing manners, spacious interior, and rugged simplicity make her a compelling partner for coastal adventure and extended cruising alike.

Pros

  • Bilge-keel option allows drying out on tidal grids or beaches
  • Above-average headroom and practical two-cabin layout
  • Teak interior with natural resistance to moisture
  • Masthead rig lowers heeling moment for easy handling
  • Heavy-displacement hull delivers a comfortable motion at sea

Cons

  • Modest sail-area/displacement ratio makes for leisurely light-air progress
  • Fin keel provides less directional stability than a long-keel design
  • Capsize screening value of 2.03 excludes the boat from ocean racing
  • Small production run means a more limited owner knowledge base
