The Severne SDM90 is our durable race mast. Added fibreglass increases strength and makes it less susceptible to impact damage.
The SDM90 utilises an Integrated Ferrule to ensure the join does not change angle over time.
The relationship between the mast and sail needs to be matched with finite detail. The correct curve and stiffness ensures that the response, shaping and twist are consistent with not only the original design objectives but also with the controlled conditions we test each and every one of our sails.
At Severne, our analysis of mast performance extends far beyond the two dimensional IMCS system with only 3 reference points. All Severne masts are tested at 7 designated offsets and computer faired to precisely mirror the luff curve of the sail.
Every mast in every range is produced using pre-preg carbon construction. This way the resin consistency and content can be managed down to sub millilitre perfection and the fibre content and bias controlled, which optimises strength and reduces weight.
