Hello Bryn, you said - "I can't help but think that actually being a bit higher up will give you more power over the rail and how it enters the water as you have more leverage." It's a theory but I don't think that's the case. To transfer power you need stability & low centre of gravit...

Sorry Bob but it doesn't answer the question above.

Rather than repeating myself, I will come from the other angle. How does extra volume under your knees aid performance once you are up & riding? Wave energy has no bearing on this. If that volume never enters the water [while riding] all it does is give you a higher centre of gravity, less feel,...

All I'm hearing here is the effect on wave catching/paddling ability. I was not interested in that, only the improved riding performance. I have tried to bring to the discussion the benefit of lower volume under your knees & where the foam is of no hydrodynamic importance while up & riding. ...

"Two questions - 1 If you were to take a strip/block of foam out [say 100mm wide x 1m long, so that it drained out from the tail end] from between your knee positions down to the glass on the bottom, would it affect the performance of the board while you are riding it? [Purely from the point of...

"as for putting on a few pounds...speak for yourself, mate. i'm a bronzed hunk of lean, sculptured aussie muscle." Ha Lefty....I thought I would make it emotive to get a reaction! Hopefully design doesn't stagnate. The process for me is understanding what each element does & then takin...

I think the essence of what I am saying is that once up & riding, thickness is only a drawback...providing you have the same rails. How can it help? So from a performance point of view it is a negative. Lower COG = more control & power. The only downside is paddling ability, which takes me b...

"I think paddle speed is greatly influenced by width as well as rocker and those 26 litre blades probably un stick and release a whole lot quicker than a 17" nosed kneeboard does as well as being able to get more purchase with your arms with less width." Not sure about that Bryn...a s...

Hello Bryn I hadn't seen your post! I think much of the sensation when riding a thicker board is down to rail thickness - "Once up & riding a thick board has little influence other than being slightly harder to control.....you can have the same rails so that the buried profile remains the s...

Thanks for the reply eq. You are not your average build so I can see you would need some extra foam...I'm guessing your board would come in close to 50 litres. If you need that kind of volume to catch waves then you are on the right board but when the waves pack a punch don't you find it hard to duc...

if you want less foam then the velo spoon is for you... i always thought the genius of the kneeboard is that it manages to pack a lot of foam into a board and still make it high performance. I'm pleased to say that we don't need to be that polarized. There is much fertile ground for both discussion...

I would say most shapers would be making a board around the 40 - 43 litre mark for your weight...but I was thinking more of like for like....someone in the region of 160 - 170 lbs. If you have a full deck pad there is at least a good case for removing that amount of foam from the deck...I don't thin...

Is the volume really necessary?

The average kneeboard has a volume of around 36 - 38 litres, add in a deck pad & you've probably got three more.....do we need it? The average performance shortboard is probably closer to 26 - 28 litres & they are being spun around for a Teahupoo take off.....& some of us have flippers t...

I would say don't stretch it more than 6' 2" x 24" x 3" & dont fatten the rails up too much but dome the deck to increase float.
