01. Standing Rigging
Armare Ropes has developed a complete retrofit system to replace rod with textile standing rigging.
Armare standing rigging systems are the perfect choice for those who want to get the best from their boat, whether for a new project or a retrofit application, because it is easy to install and use, it doesn’t require many interventions on the current rigging and its maintenance is simple.
The cables are made of continuous PBO-Zylon multifilament, with the same techniques used for single cables. The apparent simplicity of these cables, hides a complex construction. Although it is always made with the “sling” system, and the production is handled by a special machine, that controls at any time tension and winding of the yarn, a considerable part of the work is done manually.
The result is a great attention to details, in particular those that are not visible, that’s to say treatments, finishes, protection and processes that are an important part in the construction of the cables. Actually these details affect the durability and the overall performance of the finished product.
of textile systems
The installation on board of a textile standing rigging is facilitated by the lightness and the flexibility of the cables; the use of PBO® cables allows the elimination of many parts of the additional fitting, e.g. the S.S. heads of the spreaders. The optimization of the fitting provides further reduction on the total weight of the rigging, together with a drastic decrease of the necessary time for its installation. The cleaning of textile standing rigging ensures an optimal aesthetic result.
The adoption of PBO® textile rigging provides various benefits to the performance of the sail boat, which may vary, according to dimensions and the proportional reduction of weight.
E.g.: on an 80 feet yacht, the weight of the traditional standing rigging reaches over 300 kg, compared to 80 kg of corresponding PBO®. This weight reduction translates into an improvement of the righting moment, which can be exploited for example by removing a weight in the keel as per 1:5 ratio (1,000 kg to remove from the keel). The reduction of movements of the mast exceeds 12%, with an increase of boat speed and the reduction of rolling and pitching.
Thanks to the general lightening of the rigging and the visible improvement of the righting moment, the boat can sail faster. The performance betters reaching easily 1%, which translates to a distance of 100 miles equates to a saving of about 10 minutes. The possibility to profit by an improvement in the righting moment permits the designers to change weight distribution in order to achieve the aim to improve the performance.
The movements of roll and pitch are definitely lower. It is calculated that, with the adoption of a textile standing rigging and stay, the pitching can be reduced by 5% and the rolling up to 30%. Consequently, the movements of the mast are lower, with the derivation of intuitable advantages, as to say much more constant and linear behaviour of the boat, especially with wave, in favour of a better quality and speed of the navigation and at list much comfort on board.
The development of alternative rigging solutions allow
for remarkable results in terms of lightness and performance,
thanks to the use of innovative high modulus fibers such as
PBO-Zylon®, Kevlar® and Dyneema®.
Armare Ropes tests and produces complete high-tech retrofit
solutions, thanks to the collaboration with professionals in the
rigging sector and the production of high-performance ropes,
made with high-tech fibers.
How does the system work
As shown in the figure below, the vertical (V1) and the diagonals (D1, D2, D3) are connected to the standard housing of the mast through the terminals, included in the textile standing rigging. Each steel fitting also has a regulation of about 70 mm. The vertical and the diagonals, excluding D1, are composed by a single cable, with the added benefit of a reduction of weight and complexity of the system.
External or internal spreader
There are two different techniques for the passage on the spreaders, that are called External spreader (Fig. 1 and 2) and Internal spreader / Tip Cup (Fig. 3).
In this way, for example, the passage of the vertical on the third spreader is completed with a simple binding, which keep in seat the cable, while the passage on the first spreader is inner, using the existing seats (Tip Cup). Any change to the heads of the spreaders are made directly from Armare. Finally, a simple steel fitting system allow the link between the deck cable (V1) and the diagonal (D1), that are taken to the right tension through special stainless steel turnbuckles.
