Hot Rod Ultra 100% Carbon RDM Masts

18 Months of Development – The Highest-Performance Mast on the Market

The ULTRA 100% carbon mast took 18 months to develop. We wanted the best, and it takes time to achieve perfection.

The ULTRA is a no-compromise mast from the initial concept right through to the final product; no expense has been spared. We set out to make the highest-performance mast on the market. All fibers in the ULTRA are carbon, including the boom reinforcement.

Pure Carbon – Nothing Added, Just Performance

Our mast is pure, nothing added, just carbon. Following the success of the Firelight, we were determined to produce a premium-quality mast that would surpass all others in terms of weight while remaining strong and dependable in tough conditions.

Tested to Destruction in Brutal Hawaii Waves

Throughout the development phase we tested countless masts from five different carbon factories to destruction in the brutal Hawaii waves. We constantly re-evaluated the performance and characteristics to ensure that the new mast perfectly complimented our full range of sails.

The new ULTRA RDM mast is lighter, reacts quicker and will take a respectable beating.

Made in the EU with British Sourced Prepreg Carbon

Made under tight controls inside the EU with British sourced Prepreg carbon, the ULTRA 100% carbon mast is the performance boost you were looking for and your rig will never quite feel the same again!
