Duotone windsurfing masts from the UK's Duotone specialist: the 100% carbon Duotone Platinum SLS and Platinum AERO 3.0, the Gold.90, Silver.70 and Black.50 series, the EPX range and the adjustable EPX.AL Grom kids' mast, plus Ezzy and Seasprite masts for Ezzy sails. Available in RDM and SDM.

Our advice: buy the Platinum once

Virtually everyone ends up on a Duotone Platinum SLS 100% carbon mast. It's an investment, but it's the last mast you'll need to buy. It's very light, it gets the best performance out of your sail, and it lasts a very long time. Duotone back it with a 2-year unconditional warranty on their SLS hardware (masts, booms and extensions) when you register within 30 days. Break it, and Duotone replace it.

Duotone barely change their mast bend curves from year to year, so a good Duotone mast keeps working with new Duotone sails for many seasons. Duotone sails are designed around Duotone mast curves, so for the best result pair a Duotone sail with a Duotone mast.

The Duotone mast range

• Duotone Platinum Series AERO 3.0 (RDM 370, 400, 430): 100% carbon in T900 carbon quality. The lightest, most reactive mast Duotone make.
• Duotone Platinum Series SLS (RDM 340-460, SDM 380-550): 100% carbon, T800 carbon. The lightest RDM mast in its class and the mast we recommend most.
• Duotone Gold.90 Series (RDM and SDM): 90% carbon, T700 carbon. Very close to Platinum performance for less money.
• Duotone Silver.70 Series (RDM 370-430, SDM 430-490): 70% carbon. A solid all-rounder.
• Duotone Black.50 Series (RDM 370-430, SDM 430-490): 50% carbon, T600 carbon. Durable, great value.
• Duotone EPX.90, EPX.40 and EPX.25 (RDM and SDM): Duotone's budget-friendly everyday masts, in 90%, 40% and 25% carbon.
• Duotone EPX.AL Grom (60/90, 100/130, 200): an adjustable aluminium mast for kids' rigs.

RDM or SDM?

RDM (reduced diameter mast) is the thinner mast. It's what we use for wave sails, and what most windsurfers on the South Coast of England ride. An RDM sits a little looser in the luff sleeve, which gives the sail a little more forgiveness and power. RDMs are also easier to grip and come in shorter lengths (340-460) for smaller sails.

SDM (standard diameter mast) is the wider, stiffer mast that big freeride, freerace and race sails need, particularly cammed sails, where the wider diameter fits the cams. Always check the mast type, length and IMCS on the sail's spec table.

Masts for Ezzy sails

Ezzy sails are designed around Ezzy's own mast curves, so we recommend the Ezzy Hookipa C91 RDM and Ezzy Legacy C60 RDM masts for them. The Seasprite 40% Carbon RDM mast is built to the same bend curve as Ezzy sails, so it's a lower-cost alternative for an Ezzy rig.
