The first sail making mold for 3D monofilm sails was made in 2011. and slightly changed in 2012. It was designed to allow all IOM sails to be made using the same mold. After two years of extensive trials and testing of sails and improvement of sail manufacturing technology, it was clear that such designed sails could sometimes be difficult to trim. Thus we have started an extensive testing of new shapes for our molded sails, one mould for jib and another mold for mainsail (all marked as “mold 14”). Our aim was to have sails which could be easy to trim for various wind speeds using as flat as possible sail shapes having in mind light wind speed performance. In the year 2015 (mould 15) we have developed new sail shape that we truly believe are excellent all-around flat water sails. In 2016. extensive research and development produced ‘Mold 16’ that is similar to ‘Mold 15’ but deeper, and these sails won World Championship in France, 2017.!
New sailmaking technology was developed in mid-2014 allowing easy exchange of the sails making mold from one to other. Manufacturing time was shortened and sails made using new technologies are generally better than the old ones.
Starting from 2015, translucency sail material is used for sail making. (Similar material is used by most other IOM sailmakers.)
Sailmaking mold made in 2012. was being used as a standard option up to December 2014. Sails made from December 2014. to end of March 2015. have been made using ‘Mold 2014.’ and after that, we were using ‘Mold 2015.’ as standard. After January 2016. we changed to ‘Mold 16’ because such new sails proved better in the majority of wind speeds and other conditions.
Sailboat RC will continue our extensive R&D of new sail shapes and material processing, so you can be sure that sails offered on our website as factory “standard” (default) are the best option for most weather conditions.
