MK CPSL MKII Full Carbon Freerace Windsurfing Boom 190-250cm
Model Code: CPSL (Carbon Pro 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.
Features
- NEW! Upgraded oversized mast cup
- NEW! Wide tailpiece
- Monocoque construction
- Three pulley tail fitting ready for adjustable outhaul set up
- Integrated removable RDM mast adapter to boom head
- Ergo Grip around the grip area to increase grip comfort and also boom stiffness
- Oversized 36mm tubing at rear for maximum stiffness tapering to a very comfortable 29mm at grip area

2023 Severne Blade Windsurfing Sail – Anthracite 4.7 & 5.7
BLADE _CONTROL ORIENTED WAVE
The Blade has defined the 5-batten wave sail category for nearly two decades.
With the new GRADIENT PANEL TECHNOLOGY improvements are obvious. Lighter weight and better stability.
Corners have overlapped panels which reduces the amount of patching. At the same time, these overlapped areas extend into the body of the sail so it transitions the load much better, will be less stretched over time. It’s a more stable way of building sails.
Rather than a single curved luff panel, the Blade uses separate panels that radiate out of the head and tack corners. This perfectly aligns the sail material with the direction of load. Previously the curved panel would have bias stretch in all the wrong places. Direct transmission of power. Increased longevity. Total Control.
