18 - 05 - 2026. MK Booms are now available in CPW wave and CPX Freewave. 

Freeride, Freerace and Slalom booms will follow.

Prices have risen but the MK Carbon booms have a great track record and even at the new pricing, they are still the cheapest Carbon on the market.. as far as we know! 

Carbon Booms for Wave / X-Over /X-Over Freeride / Slalom / Race. The front end on all models is known as an Aeron Mk7 product, which has a removable RDM shim to make it dead easy to swap between RDM wave masts and SDM freeride masts. The back end is carbon, with a Loop and Go system on the CPW / CPX booms whereas the CPS and CPSL have a triple pulley race cleat block. Adjustment range is marked on the rear ends for easy rigging. MK say...

CPW  Wave

NEW! Upgraded lighter and stiffer 100% carbon layup.

We designed this boom with the wave/freeride sailors in mind. The slim diameter of 25mm makes it a skinny boom which seems very popular with wave sailors because it reduces forearm fatigue. The range will be compatible with sails from 3m to 5.5m.

CPX The MK X-Over Boom

NEW! Upgraded front end and tail fittings and also new wide tail option for £10 more. We designed this boom with the wave/freeride sailors in mind. The slim diameter of 27mm makes it an easy gripping boom without sacrificing the stiffness and strength when compared to smaller diameters. The massive range will be compatible with sails from 3.5m to 7m which pretty much covers the majority of sailing conditions.

CPS Mk3 Freerace   

This boom was designed for the larger sails and the and foiling in mind where you rarely go over 8.0m. The tapering oval grip makes the grip area a comfortable 29mm while retaining the stiffness required for big sizes even at maximum extension. This now comes complete with wide tail and a taller front end cup.

CPS Slalom

This boom was designed for the larger sails and the rigours and load of the Slalom format. The tapering oval grip makes the grip area a comfortable 29mm while retaining the stiffness required for big sizes. This boom is truly outstanding in that the stiffness is right up there with booms costing twice the price. This when compared with the CPS has a wider slalom bend curve and a wide tail to minimise the sail touching the boom arm thereby giving the sail more power. If it is more control you want, then consider the CPS.
