The demand for lighter masts (and booms) shows no sign of abating as owners request ever-lighter displacement cruising yachts. Anticipating this trend, Rondal became involved in the carbon fibre field at an early stage. Assisted by the Dutch Aerospace Laboratory at the design stage, it is believed that Rondal has chosen the best way of production.
Characteristic for the Rondal carbon fibre mast is that, whatever the length, the mast is built in one piece. Building the mast in one piece has the huge advantage that the fibres in the 0° layers run from top to bottom without any interruption in the fibres. All compression forces can be guided safely through the laminate.
When decided to request price information please send a deck- and sailplan. With this information we can inform you better.

Since 1989, Nordic Mast has been building masts in carbon fibre for yachts ranging from 30 to 100 ft. Each mast is built to the specific calculations and dimensioning prepared by our engineers, based on the data of the boat and the requirements of our customer. Nordic Mast is now capable of building masts for yachts of up to approximately 125 ft.
Production of carbon fibre masts has become a Nordic Mast specialty, attaching great importance to details and customer requirements. The integrated components of this mast are all made of carbon fibre, providing optimal strength, weight, and corrosion resistance.
The benefits of a carbon fibre mast are manifold; in addition to the balance between strength and weight the life of a carbon fibre mast is basically infinite. This overcomes the traditional problems of aluminium masts in terms of oxidation and metal fatigue, which will not occur with carbon fibre.

It's no coincidence that carbon fibre is used in aeroplanes. Carbon composite combines stiffness and strength with low weight. Selden low-weight carbon spars have accentuated longitudinal stiffness. This means that forestay tension can be substantially increased. All experienced racing sailors know what this means in terms of increased performance. The combination of greater stiffness and reduced weight will bring you beyond the speed limits.

Formula understands the science of Carbon Fibre technology, and engineer rigs using finite element analysis. This enables us to confirm the loads before a single piece of pre-preg carbon fibre is cut.

Hall seamless carbon-fiber masts have no peer in the combination of light weight, stiffness, and the ability to tune easily for changing conditions. Hall is the choice of the winning Cup crew in the last two events.

CST Composites manufacture a range of mast sections, available in standard modulus (SM), intermediate modulus (IM) and high modulus carbon fibre (HM). These can be supplied with any wall thickness requirement and fibre orientation.

Southern Spars has established its place as a world leader in the design, construction, installation and servicing of carbon-fibre masts, booms, composite components and EC6 rigging. Its rigs power a wide range of yachts, from one-design to grand prix racing, cruising yachts and superyachts.
Innovation, quality and an insatiable desire to produce what the customer requires runs through the company’s culture. These qualities have contributed to producing product for numerous race victories, including the Volvo Ocean Race, Vendee Globe, Sydney-Hobart, plus supplying rigs to some of the hottest one-design classes. The same design expertise, manufacturing methods, materials and components utilised on these racing rigs are applied to every rig built by Southern.
Southern’s operations extend to four corners of the world, with centres in New Zealand, USA, France, and South Africa

Carbon composites are known for their:
High fatigue tolerance
Stability under environmental exposure
Exceptional strength to weight
All these features make carbon composites attractive not just for the construction of mast tubes and fittings, but also for standing rigging.
Composite Rigging installed the first full set of Element C6 carbon composite rigging on the Farr 52 Georgia in Auckland in March 2003. This set includes all shrouds, jumpers, running backstays and headstay. These pieces now have over five years of service without incident.
Since that time EC6 has been installed on a variety of yachts ranging from 30’ sport boats to 50+ meter Megayachts.
The first set of EC6+ continuous rigging was installed on the Farr 60 Numbers in the spring of 2005. More recently the Open 60 Paprec-Virbac won the Barcelona doubled handed nonstop round the world race with EC6+ carbon shrouds. Post-race testing confirmed that there was no strength degradation. The rigging has been refurbished and reinstalled for the next event.

SPARS, POLES & TUBES
We have amassed a broad selection of mandrels over the years and can provide spinnaker poles, bow sprit tubes and whisker poles for just about any boat from 14 to 90 feet.

The carbon fibre boom distinguishes itself by having a low weight, high strength, and a unique design and appearance. Our design team will take all the needs and specific wishes into the design of the boom
Primarily, there are two types of carbon fibre booms. The ordinary boom, known from small yachts, and the Park Avenue boom, used on the big mega yachts on which the size of the mainsail is so bigand heavy that it will require the boom to have ”wings” which will carry the sail when lowered, generally supported by lazy jacks.
Nordic Mast has its own moulds and tools for making carbon fibre booms. Nordic Masts use the same technique and engineering principles for the boom structures as we do for our masts. Nordic Mast is only using leading products in the making of our boom.
Small but very fine details on the PARK AVENUE BOOM as he incorporated track for the boomcover and the suncover are two of the standard features on the product.

The Nordic Smart Boom is available for new as well as existing booms and is made customized in carbon fibre to keep its weight down to an absolute minimum. The primary purpose of the Nordic Smart Boom is that of "picking up" the mainsail when the sail is lowered down on the boom, the boom tarpaulin is zipped, and the sail is stowed away.
Nordic smart Boom primarily targets boats ranging between 30 and 50 ft.; above that, we would recommend the Park Avenue boom. No matter if you have a new or older boat and you are looking for easy handling, a refined look, the Nordic Smart Boom will fulfill your needs.

Class rules will usually define whether spinnaker poles in carbon fibre may be used. Carbon fibre poles are typically used on every size boats as they are far easier to handle and offer amazing strenghts for weight advantages.
All spinnaker poles are available painted to our customer's colour specification.
Carbon fibre spinnaker poles are available as standard in "raw" carbon fibre, clear coated, or painted. Carbon fibre poles are now available with the logo and name of the boat, as well as other information, cast in the laminate. This is an added advantage as this branding is a preventive measure against theft of the pole.

We have developed our own computer controlled manufacturing method in which prepreg (pre-impregnated) tows are wound onto a mandrel (cylinder) prior to oven curing. This method enables us to exercise full control over every stage of the manufacturing process and guarantee products of consistently high quality. One of the big advantages of this Selden production method is that it enables us to achieve sufficient durability in the areas subject to the greatest loads and wear.

CST have just released a new standard range of spinnaker poles. Please select poles by their maximum length, boat size is given as a guide only. CST also manufactures bow poles and receiving tubes, for dinghies, through to sports boats and larger yachts.
The poles can be supplied as bare tubes or complete with machined plastic plugs, selected end fittings and trip lines (bridles not included). There is also the option of including an aramid wear patch and poles can be clear coated with polyurethane for UV protection.

Formula are able to supply quality spinnaker poles in Carbon or Aluminium from 3 inches to ten inches in diameter.
Engineered to suit boat use, we use a mix of custom or branded pole ends and adaptors.

Hall carbon-fiber poles are manufactured using the same aerospace-quality, seamless construction process as our extraordinary masts and booms. Each pole is custom molded on a male mandrel then autoclave-cured to eliminate voids. Hall uses unidirectional, pre-preg carbon fiber for the pole's structure, resulting in maximum strength at minimum weight.
Hall Spars & Rigging spinnaker poles are made for intense sailing. Hall poles save weight on deck, are easier to handle (half the weight of aluminum), and are incredibly tough. Kevlar in key areas protects the carbon from chafe.
