Selden Yacht Masts

Selden 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).

Please get in touch to discuss your requirements if you are considering a new mast.

Alternatively, you might need help with spare parts and after-market service. Since 1992 Selden have engraved a unique code into each mast section. It's called the mast ID number and you find it at the lower end of the aluminium section. This number tells us when your mast was built and what parts were used all the way down to nuts and bolts. The mast ID number includes the designation of your mast section, which enables you to find part numbers in catalogues and on our website.

We stock a wide range of service and replacement items for masts. Many of these are listed below. If you can't find what you need please do get in touch.
