AC72 (Wing Sail)
The AC72 is a wing sail catamaran box rule, governing the construction and operation of the yachts to be used in the 2013 Louis Vuitton Cup selection series and the 2013 America's Cup. This new and revolutionary design is extremely expensive and has allowed the development of foils which lift the hull out of the water in some conditions leading to extreme boat speeds.
Alegre (Mills 72')
The latest Alegre is an exciting development in the intense design race of the IMA Mini-Maxi fleet, perhaps the top level owner-driver racing on the planet. The IRC 72 Alegre has been launched for owner Andy Soriano. Boasting an innovative deck layout and numerous unique solutions to produce a cleaner, lighter, and stiffer design which is easier to sail.

The 16’ skiff is a unique Australian high performance three man dinghy that has a long history being sailed for over 100 years. To keep costs low and provide closer racing, in 1998 strict rules for hull design and construction were introduced. The new design rules only allowed for two masts, three jibs, two mains and two spinnakers. Boats utilise these sails and rig combinations for optimal performance depending on different wind strengths.

The Open 60 is one of the fastest mono-hull sailing boats, designed for speed and certainly not comfort. The ‘open’ design eliminates a fixed design but there are ‘box rules’, ie length and stability requirements which give designers parameters within which to work. Southern Spars designs exceptional custom rigs to owners specifications, within the box rules.
The class is governed by the International Monohull Open Classes Association (IMOCA). Sailed singlehanded, Open 60s are raced at the extremes of the sport including the round-the-world Vendee Globe and Velux 5 Oceans races.

The Starling class yacht was conceived as a stepping stone between the P-class and adult yachts. It was designed by Des Towson in the late 1960’s and has become one of the largest dinghy fleets in New Zealand. With the new advent of carbon masts it has made the Starling mast more robust during extreme weather conditions and extends the masts maintenance longevity. The design of the mast replicates the bend of the alloy masts, while also ensuring the current optimal crew weight range of 60kg-65kg is maintained.

It is Sail World magazines winner of the 2010 boat of the year, for best IRC racer. The Summit 35 is a direct development of the Summit 40 design, it is a dual purpose IRC Cruiser-Racer. It retains the key styling and performance characteristics that made the Summit 40 such a success and is designed to excel under IRC by combining stability and power of a large sail plan and deep bulb keel. It has a two spreader alloy rig that supports masthead spinnakers flown either from an optional retracting sprit or the standard over-length carbon spinnaker pole. This simple keel-stepped rig configuration is controlled by a standard integral hydraulic backstay adjuster, and allows non-overlapping jibs for the optimum combination of performance and ease of use.

The TP52 is an exciting class of yacht that races grand prix circuit style without handicap, attracting substantial spectator and media attention.
They are extremely fast carbon fibre yachts that are built to ‘box rules’, allowing owners to select their designer, spar builder etc. The TP52 Class does not limit the number of professional crew onboard, and owners each have a vote should they wish to change the box rules.
Built by Custom Projects, each TP52 rig is designed and built to meet the owner’s requirements within the box rules.
Twelve One Design
The ‘Twelve’ One Design is a new class of yacht that has been developed by Europe Sailing Corporation Ltd to fill a gap in the sailing market for a modern and sleek, low-cost, easily transportable boat.
The boats have been designed to reflect the look of the latest America’s Cup Class, albeit smaller in size, with a length of 12m and 2.49m in width. Thus, allowing for boats to be transported without need of a special transportation permit.
Designed by Studio Lostuzzi, the ‘Twelve’ One Design class will be built using an “E-glass” and PVC sandwich construction bonded with epoxy resins, and will feature a Southern Spars’ two spreader carbon fibre mast manufactured at our Cape Town facility.
