2021 Severne Blade Windsurfing Sail – Red 5.3m
BLADE
CONTROL ORIENTED WAVE
The 021 Blade is the benchmark 5-batten wave sail. A perfect blend of power and control.
When you need dependable performance across a wide wind range you simply can’t beat the stability and control that 5 battens provide. Based on this fundamental we built the Blade to be the ultimate all-rounder wave sail.
/ Increased skin tension stabilizes the profile for maximum wind range.
/ Dacron luff panel maintains flex and soft feel.
/ Control-oriented geometry positions the clew lower where it can be easily managed.
Constructed entirely out of premium X-Ply, the Blade is one of the most durable sails on the market, yet intelligent design means it’s also one of the lightest. SpiderFibre technology has radically reduced swing weight whilst also creating a much stronger clew. Dyneema window X-Ply allows for unrestricted vision. Upper panels in eM3 reduce swing weight. The new highly durable yet lightweight eM4 material is used in the high load foot area. Engineered for performance.
The 021 Blade is the sail to choose for all-round high performance.
/ I00% XPLY
/ DOUBLE SEAMS EVERYWHERE. / BENCHMARK WAVESAIL
/ UPGRADES FOR 2021
/ LIGHTER FEEL
/ INCREASED STABILITY

Severne Cyclops RDM Mast Extension
RIG YOUR SAIL IN UNDER 1 MINUTE
The CYCLOPS extension has a single pulley for rapid loop ‘n go rigging. Simply pass the loop of rope through the tack pulley on the sail and hook it over the single pulley on the extension. A single pull applies full downhaul tension in seconds.
All the ropes and pulleys are kept in perfect alignment to eliminate a lot of the friction and makes up for any loss of leverage from less pulleys.
A built-in handle negates the need for any tool, and stuff into the downhaul pocket on the sail.
Formuline rope is used to further reduce friction and minimize rope wear.
Faster, simpler rigging.
