2-Bolt Windsurfing Base
What “2-Bolt” Denotes: A base that uses two bolts to secure itself to the board. Most 2-bolt windsurfing bases are a two part system with a base plate that is left on the board.
Convenient: No tightening a base by hand. No post session, my-hands-are-tired hassle. With a 2-Bolt windsurfing base, attaching and separating a sail is a snap.
Clever: Chinook’s 2-Bolt Base integrates a 6 mm hex tool into the base itself. To secure, adjust, or remove the Quick-Release Base Plate, there’s no searching for tools.
Tuning: With two securing bolts, only a small portion of a board’s mast track is useable for sail positioning.
Moving Parts: There’s more of them with a 2-Bolt base. That said, the Big Winds rental fleet has used 2-Bolt bases for decades. It has been our workhorse, and a reliable one.
Weight: Up to 0.2 pounds heavier than 1-Bolt bases.
Families, couples, big quivers — the convenience 2-Bolt windsurfing bases offer is tough to beat. Shave rigging time. Swap sails in seconds. Most 2-Bolt users have a base plate mounted on every board they own, ready for plug-and-play action.
Rubber Base Vs. Tendon Base Vs. Mechanical Base
Rubber Windsurfing Base
What “Rubber” Denotes: The rubber hourglass-shaped part that joins the top and bottom portions of the base.
Longevity: Chinook’s most durable base — especially in tropical environments.
Smooth Riding: Offers an exceptionally cushioned ride through chop
Protection: The most shock absorption of any windsurfing base. Jump without worries.
Waterstarts: The soft rubber joint makes boards less likely to flip over while sail positioning in high winds.
Efficiency: Riders who prioritize planing and acceleration prefer a more positive, direct transfer or rig power.
Availability: Just one 1-Bolt US Base model is currently available.
Anyone who wants a smooth riding, long lasting windsurfing base that can handle the elements, high winds, and high jumps.
Tendon Windsurfing Base
What “Tendon” Denotes: The dark black tendon that joins the top and bottom plastic portions of the base.
Balanced Performance: Stiffer than Rubber Windsurfing bases, softer than Mechanical Bases. The middle road. Positive, direct transfer of sail power. Good shock absorption for jumping and smooth riding.
Maintenance: Not quite as as durable as rubber windsurfing bases, but close, and far more serviceable. Replacing a tendon is easy with a $19.25 part.
Availability: 1-Bolt, 2-Bolt, Euro-Pin and U.S. options exist. Our most popular base system at Big Winds.
Sensitivity: Slightly more vulnerable to tropical environments than Rubber bases.
Most windsurfers. Tendon Windsurfing bases blend efficiency, reliability and forgiving riding. The most widely used base system in the world, and easiest to service.
Mechanical Windsurfing Base
What “Mechanical” Denotes: The interlocking plastic pieces that join the top and bottom portions of the base.
Efficiency: The most positive, direct transfer of rig power. Ideal for maximizing sail power in light winds.
Convenience: The easiest base to attach and separate rigs. Pop a sail on or off a board from any angle. No need to turn a board on its side.
Durable: Chinook rarely sees issues with mechanical bases, though most mechanical base users sail in gentle winds and flat water.
Stiff: So stiff, jumping isn’t recommended. Mechanical bases offer no shock absorption for boards or their riders.
Light winds, wide boards, flat water, windsurf schools, and, more recently, windsurf foilers. If easy rig attachment and separation is the priority, this is the base.
U.S. Cup Versus Euro-Pin Base
U.S. Cup Windsurfing Base
What “U.S. Cup” Denotes: The plastic part on top of the base, which includes two protruding aluminum pins.
Sand Resistance: The U.S. Cup creates a relatively closed system, less vulnerable to sand intrusion and corrosion.
Proven: A base that’s been in existence for decades. For many, it’s a known quantity that’s easy to trust.
Long Term Use: Aluminum pins may eventually need replacing. U.S. Cups occasionally need tightening.
Ease of Use: Squeezing two pins together to release a sail is tough with tired hands.
Those who want to keep on keeping on with a base system that’s never given them reason to change, and that’s likely already compatible with their existing extensions.
Euro Pin Windsurfing Base
What “Euro Pin” Denotes: The singular stem located at the top of the base. Also referred to as “Universal Pin”.
Trustable: Chinook’s team never hears of these bases releasing accidentally, and claim that Euro-Pin Bases require the least long-term maintenance.
Direct: Euro-Pin Bases create a tight, snug fit between the base and extension. No play whatsoever.
Convenience: Release a sail by pushing one pin (read: not squeezing two).
Sand Resistance: More vulnerable to sand intrusion.
Tired hands looking for sail separation relief. Any windsurfers who want a base built to last, that – in a world of mast base options – is the least likely to ever need servicing.
