New Boat Order

The Southerly 42 features the highly developed Swing Keel which gives the freedom and versatility to sail in almost any waters. With the keel lowered (8' 11"), the deep draft makes for fast, serious cruising. At the ‘touch of a button’ the keel can be raised to give a shallow draft of just 2' 9" – perfect for shallow water exploring.

When the Southerly 42RST was first developed, Humphreys Design commissioned a fast, modern hull for good performance, with the stability and comfort for cruising. Deck styling and a sociable cockpit layout with twin helm positions, designed by Stephen Jones, created one of the most comfortable and easy to sail cruising yachts available.

With excellent build quality and exquisite interiors, Discovery Shipyard have brought a wealth of knowledge and practical design to the Southerly range. The time is now right to revitalize the Southerly Yachts brand and what better way to launch than with the 42.

The Southerly 42 is built to order by Ocean Shipyard Limited in the UK.

The Southerly (variable draft) range includes the Southerly 42 and Southerly 48

Heavy duty composite molding, incorporating an anti-print through and moisture barrier, multi-axial, and unidirectional reinforcements with vinylester laminating resin and isophthalic gelcoat. The keel box is an integral part of the hull lay-up and sandwich construction stiffening runs the entire length of the hull topsides. All main bulkheads are bonded into the hull at main lay-up stage along with a stiffening grillage of transverse frames and longitudinal stringers. The engine bearers are an integral part of the hull structure.

The 42 features the highly developed Swing Keel which gives the freedom and versatility to sail in almost any waters. With the keel lowered, the deep draft makes for fast, serious cruising. At the ‘touch of a button’ the keel can be raised to give a shallow draft of just 0.84m (2' 9") - perfect for shallow water exploring.

The fixed ballast is an iron casting which acts as a grounding plate and stiffener for the keel and housing assembly. It is fitted into a recess in the hull in the area of the keel box with stainless steel bolts. The aerofoil shaped keel is cast iron and incorporates a stainless-steel pivot at the leading edge. The keel is raised and lowered by a dyneema pennant and hydraulic ram powered by an electrically driven pump with a hand operated back-up. All hydraulics are easily accessible for maintenance.

  • Keel control and gauge showing keel position fitted at the helm
  • Removable stainless-steel pin, positioned to enable the keel to be locked in the ‘up' position
  • Manual rocker switch at pin position for fine adjustment
