Who would ride it? 

Anyone who can ride or wants to ride a skateboard, snowboard, wakeboard, or surfboard would also find this appealing.  All of the board riding sports can readily transition.  For a more detailed presentation.  Click Here

How much water flow is needed? 

4,500cfs would give us a nice wide wave about 6ft tall.  This can barrel or be a soft longboard wave.  More flow can make bigger waves and less flow makes smaller waves. 

Where can you get that much clean water?

The output of a hydroelectric dam is clean water on a steady schedule.  There are many of those across the globe.  This should not be limited to just Hydroelectric dams, but they are ideal.    

What is the bottom made of?  Does it hurt to fall?

 “When the wave breaks here, don’t be there”.  That’s not folklore.  That’s real.  The bottom is concrete with foam padding at strategic impact points.  Namely where the lip of the wave lands. The largest safety feature on the Reef Pass System is the water depth.  The lip of the 6 ft barrel lands is 30 inches of water.  Just like Kelly’s wave and just like real ocean surfing on reefs and sandbars.   Everywhere else is deeper. 

How do you get out after a wipe out?  That a lot of water pushing downstream?

Getting swept downstream is real, but harmless.  It transitions from a singular wave rapid full of turbulence to a lazy river in a matter of feet and second.  There will be a large settling pond or strategic eddies to get out at. 

Who can ride it? 

The variety of waves we can produce is important.  Most surfers don’t have the skill to surf Pipeline.  Almost anyone can learn to surf a longboard on the gentle waves at Waikiki.  Surf instructors will be able to teach most people who want to and starting on a boogie board still offers a thrill for the less athletically inclined.  

How much does it cost?

Municipalities control the rivers.  Some are open to the idea of river surfing and have already built waves through public funding and grants.  These are free to the public to ride as community enhancement projects and public meeting spaces.  Just like parks and playgrounds.  I hope this tradition continues.  

A few wise old men have had these next two concerns.   

  • But I've river surfed.  River surfing is different.
  • Waveloch, American Wave Machines, etc. have already done this. 

Standing and sheet waves aren’t new, but nobody has done it without a ramp or a wave shaped profile underneath the water flow.  Waveloch, AWM, CItywave Etc. are all assisted hydraulic jumps.  The Reef Pass System is the first to allow the wave to naturally coalesce as a pure hydraulic jump.  Nothing underneath it.  This is why the prototype pictures are prettier than anyone else’s prototype pictures.  This waves shape is natural.   

The others are all pumped water technologies.  As such they have energy constraints and need to be water efficient.  In a river I am free of those constraints.  I use 30 times more water than a flow rider and I make waves that match the speed and shape of ocean surfing waves.  My waves are deep and clean.     

Relativity would say the board and water moving past it are unaware of which is moving, and which is sitting still.  If the speed and shape are the same, the feel will be the same.   I have done a lot of wake surfing and I am aware of the difference of the feel under your feet.  The water moves too fast for such a small wave.  The lip can’t push you back down onto the face like an ocean wave does.   The shape of the wave is wrong.  If you go back and review  every picture of a river wave or flow rider you will find the water is moving too fast and the shape is off or way off. 

By getting the speed and shape correct River Surf Systems will feel more like ocean surfing.   The experience will still be different, but so is Kelly Slater's Wave.
