1. Here is my own gross oversimplification...

Wind pushes laterally across the beam of a sailboat. The sails catch the wind, which applies a lateral force upon the boat. The mast transfers that force to the keel and hull, which pushes laterally against the water. The water pushes back on the keel with an unbalanced but opposite force. The result is forward motion.

Water is the medium under a surfboard. The water moving up the face and toward the beach applies a lateral force against the fins and hull. Gravity pulls the rider down, applying an opposite but unbalanced force back against the fins and hull. The result is forward motion. And that's where your theory stops.

I would continue, suggesting that modern surfboards surfed rail-to-rail can gain speed by turning, because turning requires rider input of energy into the system, which is used to change the angles of attack of the fins and bottom, tapping into the energy of the moving water within the wave. This applies in small waves moreso than large waves, when the wave supplies plenty of energy for speed. It also applies only to certain kinds of turns... not all turns... dependent upon a number of factors including fin foil, radius of turn, and bottom contours. Just as a sailboat can sail against the wind, surfboards can increase speed by adding wave energy to gravitational potential energy. This can only happen at certain angles of attack, not reached on your boards, and is more effective when the board/rider mass is reduced. This means modern shortboards may not have the momentum of your boards, and can't drive through sections like yours, but they can accelerate briefly.... attaining shortlived bursts of speed... through turning.

It might attribute to what shortboarders refer to as "squirt?"

2. Done arguing with the person that can't admit when he is wrong.

3. Roy, that's too much money to ask for for a surf board. It is insulting that you even post those ridiculous prices and I am appalled. Forgive me for not reading through the entire thread but what exactly would one get for that sum of money, what makes the boards so expensive, and how many have you sold?

He's not going to tell you. I also would like to know what material or design element or fabrication methods require the price to be so High.

I mean with a few hand tools and a garage i could replicate what your doing. You cant charge hundreds of thousands of dollars for something i can make myself. Lets take cars for example. I cannot build a Ferrari in my garage. A Mclaren F1 is a million dollar car. Space age technology at your fingertips, 0-60 faster than you can blink, and the ***** you would get in the car is unreal. Thats what a millionaire wants for a million bucks, not a peice of wood that does nothing. This guy cant grasp the concept. Hes going to use fancy words to make it seem like his boards are groundbreaking. His boards are super fast though? The next time i get challenged to a surf race ill think of gool ol' roy

8. Roy,

Does it at least come with a leash? Is this Nigerian money? Whats a quarter size ding repair cost? \$20,000.00? 500k and you can't go from 0-60 in under 4 seconds, AND you can't noseride? If you sell at least one you can buy that dream house on Mars.

You smoke crack. Good luck.

9. It's not insulting. You are stupid for feeling that way.
You get a wood board that is the best... Because I say so.
