Discussing Roy's surfboard designs.

Not exactly, because the magnitude of the lift produced depends also upon the size of the foil... in other words the same pressure difference over a larger foil leads to greater lift.

In addition, the existence of and magnitude of the pressure difference depends upon the factors which I mentioned previously, which include angle of attack and speed.

 

Yep, Olosurfer shaper of the year, an award for which there is only one candidate.

HYe was riding it incorrectly, it's a factual matter not an emotional matter.

In this case he isn't and he can't.

His error can't be changed by waving his supposed status around.

I respect Garrett enough to tell the truth rather than being a limp wristed psychophant.

I replied by suggesting that you might use the word 'please' and see how that works out for you.

I was responding to a post which asserted that the reason why single fins do not lift vertically against the hull is because they are foiled on both sides, and to some other incorrect content in that post.

What you have done is take my reply on its own so that there is no context, and then complain that there is no context.

If you want a 'teaching moment' try reading the conversation again, maybe you'll get it then.

Sorry but your fin noise at certain speeds is, as I said, because there is an issue with the trailing edge of the fin or fins.... this happens often and it is curable by attending to the trailing edge with sandpaper, countless people have done just this as I have... and all of this is entirely compatible with a stick making a noise when it is swung through the air..

You are 'in denial' over this.

 

I do not presume to decide the outcome of the conversation.

I can critique his surfing on my board because i observe that he was riding it incorrectly.

Extrapolating this into a wider statement which I did not make is a well known logical error in argument known as the 'straw man' tactic.

Congratulations!

 

You are confusing factual matters with emotional matters.

This is supposed to be a design conversation, and I find that it is better to do design work unemotionally.

In other words stick to the topic, if you please.

I didn't bring it up, I just responded to it after it was brought up.

Yes exactly, which is why I said that they are 'entirely compatible'.


You will find that if you foil the stick correctly and your fin trailing edge correctly both will cease to make the noise which you have been referring to.

Although you are once again off topic I must inform you that you are incorrect regarding my surfboard sales,and apparently have forgotten that I sell other products also i.e.plans, kits, blanks,fins, wax, sunblock and paulownia wood.
