New Speedwave 40RST 

We are delighted to announce exciting new sailing yachts which have evolved from our original designs at Northshore Shipyard. Our in-house design office have worked in collaboration with international yacht designer Stephen Jones, to develop innovative new yacht models, combining traditional blue water cruising qualities of the Southerly with the latest advancements in technology and the latest developments in swing keel design.


The New Speedwave 40RST boasts a fast, modern hull for good performance, with the stability and comfort for blue water cruising. The hull shape is a further development of the long pedigree of Southerly hulls. The modern plumb stem increases waterline length and a broad transom maintains volume aft, for performance and interior space. Deck styling and a sociable cockpit layout with twin helm positions, has created one of the most comfortable and easy to sail cruising yachts, available.

The Speedwave 40RST has an impressive sail plan, for powerful windward performance. The tall fractional rig with swept back double spreaders, combines a self tacking furling foresail, ideal for short handed or family sailing. The means you can tack spontaneously and effortlessly, allowing you to sail in conditions that a conventional sail plan may not allow. The large mainsail has single line reefing as standard, In-mast furling can be specified as an option. For off wind sailing an optional gennaker or Code Zero sail can be flown from the carbon bowsprit.

Next generation keel engineering

The new stainless steel keel blade is a stiffer and slimmer profile, giving improved performance, corrosion resistance and fouling protection. This also enables a narrower keel opening aperture in the grounding plate, leading to less waterflow disturbance, for a further increase in performance.

The swing keel gives superior sailing performance, plus the freedom and versatility to sail in almost any waters. With the keel lowered, the variable draft of 8’7’’ (2.615m) makes for fast, serious blue water cruising. At the ‘touch of a button’ the keel can be raised to give a shallow draft of 2’5’’ (0.755m) - perfect for shallow water and exploring coastlines.

Electric propulsion option

As a sustainable alternative to the conventional Yanmar 3JH40 - 40hp engine, the Oceanvolt electric propulsion solution is configured to achieve maximum performance and efficiency, with excellent manoeuvrability under power. 

The forward part of the cockpit is deep and wide with generous, comfortable seating, designed to provide leg bracing from the table when heeled. Coamings are gently sloped outwards for further comfortable seating. Running rigging is neatly arranged under covers on the pilot house roof and fed through to the cockpit. The central table offers dinette facilities,with a convenient hand rail, for when the yacht is heeled, and a double walkway for clear easy access around the cockpit.

The aft part of the cockpit is designed to give the helmsman the very best position to helm from. Foot wells for bracing, and comfortable seating at the each helm station offer safety at sea, whilst the twin wheel positions give a clear view to the bow, on either tack. Twin pushpit seats provide additional seating with great views all round.

The mainsheet track is located on the pilot house coachroof with control lines fed back to both helmsman’s stations, allowing the yacht to be easily managed. The steering is direct with minimum backlash with semi- balanced twin rudders to give instantly responsive steering and precise directional stability. Optional bowthruster and sternthruster can assist with easy manoeuvrability in heavy weather conditions or confined spaces.

The transom is a particular feature with a safe bathing platform, large locker for an inflatable dinghy, steps for easy access to the cockpit and a telescopic bathing ladder, designed to make your time on and in the water more enjoyable.

The layout is designed for maximum comfort with practicality and safety at sea, being main priorities. The interior styling creates a luxurious atmosphere within the yacht to make living aboard a real pleasure.

Cleverly designed joinery, durable fabrics, high quality fittings and subtle LED lighting, are all welcoming features. The raised saloon seating with panoramic views is designed to provide a supreme level of comfort.

Once you step inside, you enter a light and airy interior. The pilot house windows in the raised coachroof provide panoramic views, giving an instant feeling of space. Plenty of natural light,ventilation, and good headroom combined with ample stowage, makes living on board extremely comfortable.

The spacious raised saloon seating area provides a focal point for owners and guests, permitting comfortable dining whilst at anchor or moored, and taking full advantage of the all-round views. The galley has large working surfaces with plenty of storage. A stainless steel front opening fridge, top loading freezer, double sink, fully gimballed cooker and oven provide excellent facilities for entertaining. The chart table is in the proven, high level position for good visibility and easy communication with the cockpit. The aft cabin is supremely spacious and boasts a large centreline double berth with seating to each side, plenty of stowage and ensuite facilities. The forward double cabin is equally as spacious with long v berths and good headroom (a double centreline berth is available as an option). The forecabin also enjoys ensuite facilities.

Hull Construction

Advanced composite mouldings utilise closed cell foam core, Isophthalic Polyester gelcoat, stitched multi-axial and unidirectional glass and carbon reinforcements. The hull bottom and integral keel box is constructed in an extremely tough and resilient single skin lay-up. All main bulkheads are bonded into the hull at main lay-up stage along with a stiffening grillage of transverse frames, longitudinal stringers and engine girders.

All composite structures are engineered to produce maximum strength and durability with minimum excess weight to enhance seakeeping and sail handling characteristics.

  • Charcoal Grey boot top and style lines

  • Clear gel coat below the waterline

Deck Construction

  • Hand laid up GRP. Sandwich construction. Heavily stressed areas are additionally reinforced with uni-directional glass reinforcement. The deck is bonded to the hull through the entire length and to all main bulkheads resulting in a strong and integrated unit.
