Description
Every Seldén rig is carefully thought out, down to the last detail.
All the way from the materials and functions of the different parts of the rig, to dimensioning the right rig for each individual boat. Each component contributes to the performance of the whole rig. That is the Seldén way – experienced yachtsmen behind every aspect of design, product development and production.
CONVENTIONAL MASTS FOR YACHTS
Our conventional masts for 26-80 feet yachts are divided in two categories. The longitudinal oriented sections and the lateral oriented. Which one we select depends on the chain plate locations of the boat and number of spreaders.
LONGITUDINAL MAST SECTION
These sections are used for rig configurations with in-line spreaders or moderate spreader angles. The relationship between the length / width is 1,9 in order to create longitudinal stiffness allowing higher forestay load tensioning the backstay. Running backstays can often be avoided and the risk of mast pumping is also reduced. These rigs normally come with multiple pairs of spreaders and they are designed for the popular MDS sliders (Multi Directional Support).
LATERAL MAST SECTION
For rigs with large spreader angles, lateral stiffness is of higher importance than longitudinal stiffness. This is the result of a large spreader angle creating longitudinal stability, whereas the lateral stability is achieved by the geometry of the mast section. This makes for a mast section which is wider and rounder than the corresponding longitudinal section and therefore the number of spreaders can be reduced. These sections are popular for upgrading a boat from the 1970-90’s with a traditional style single spreader rig, but still with all the benefits of modern functions such as the Inner Wheel Sliders (IWS).
ALL OUR STANDARD RIGS ARE CUSTOM MADE
Extruded aluminium is an excellent material for making masts. This is where Seldén has earned its reputation as world leader in mast making. Today Seldén offers a full range of masts in both aluminium and carbon fiber. All rigs are custom-made, through every calculation and detail, for each individual boat. We know how much depends on the rig, and there is no room for compromise.
