All data above was created by me. So don't bet your life on it. :-)
I took all known dimensions of these boards and plugged them into AKU Shaper software to determine board volume. Then I cross checked using Shape 3D software. Next I calculated the rider weight required to sink each model, then made the assumption that when a board is sunk to 3/4 its thickness, I've got the maximum rider weight based on my skill level.
Boards listed without nose and tail widths are less accurate. C4 volumes are the most accurate, because I know all the dimensions.

Hi Dwight - have to say that this chart is genius - an objective based, rational way of board comparison is what has been lacking for people to make a board choice. I have been checking out the stats on the Naish 9'3 as it is likely to be my next board. Just a thought if you could combine an element of subjectivity as well - perhaps along the lines of flatwater stability for instance - for me my JL11 was more stable than the Starboard 9'8 which is more stable than the C4 10'6 which is more stable than the 10'diamond tail - perhaps an 'out of 10' rating. Fantastic piece of work. All the best Steve.
Thanks Steve.
I'm not sure I could add a stability rating without it being biased toward the style of board I am used to riding. I think people adapt to a style of board, then when they jump on something else, it can feel more unstable than it would to someone else more used to the style of that board.
That probably sounds confusing.
What I mean is, I'm used to thin boards. Anything I try thick feels unstable to me. But with a little time on the thick board, it feels stable, then my thin board feels unstable.
I think the C4 10'6 felt super stable and immediately comfortable when I jumped on it. When I did the same test with the 10'6 PSH, I wobbled bad until I could adapt to it. The Naish 11'6 was a nightmare for me. I tried it several times and could never stop shaking on it. Sounds crazy, but its so super thick, I could not stop wobbling.
I'm going to Oahu in Jan. I plan to stop by the Naish shop and demo a few Naish boards. I'm afraid to buy a Naish without a demo because of my 11'6 experience.
There is a quirk about PSH boards that make them more unstable than others. I'm hopeful the C4 9'3 will have more stability than the PSH 9'3, so I have a better chance to use it in all conditions, not just glass.
I can see that - 1st time on a c4 10'6" felt dodgey as hell to me (early days) - now I'm getting more comfy on my BK pro in chop - however the 10'diamond tail is esy to ride and I can stop paddling and rest in chop unlike the BK pro. I reckon the C4 9'3" is going to rock - I just fancy the Naish and I don't really want a boardroom full of one brand. Have to admit to going off the fish concept a bit as well - Too many edges - too much stuff going on.

wondering what your weight is..I too am interested in the 9'3"c4 don't wan't a board for only glass but to rip in all conditions. I'm about 185/190 riding the 27' bonga and can deal with it. Anything less stable just isn't going to work, I feel like a kook falling in the lineup all the time. Also looking at the 9'6"psh all around. I'm not real interested in the Big Boy for I feel 30" would be too wide. Any insight?

I'm on a diet. I dropped from 205 to 190 in 3 weeks. Last weekend the surf was super choppy and rough. I was doing great on my BK at 190 lbs. The people I was surfing with that day, commented about how they struggled, and how surprised they were that I was having no trouble. Weight does matter a lot.
My hope is the 9'3 C4 works in all conditions I would normally surf in.
I have a surfing friend riding the 9'0 C4 in any conditions at 155-160 lbs. That puts him 12-17 lbs under the weight in my chart. I am 18 lbs under the weight listed for the 9'3 right now. I think I'll be right were I want to be on that board.
I'm trying to avoid having to surf a 9'6. The 9'6 PSH is nothing like the 9'3 PSH. You totally give up the shortboard thrill when you upsize to 9'6.
So I'm taking the chance and going 9'3. Only if I fail will I upsize to a 9'6 later.
Congrats on the weight loss. Unfortunately, I don't think I can afford to be any lighter, but 180lbs would be sweet.
That 9'3" might be the one for me too.
I can only imagine what it's capable of....
Would be a nice xmas present to myself.
Thank you....
Hey Dwight,
I've been considering the Naish 9'3" or 9'6" or the PSH 9'3"AA or 9'6"AA. I was just curious about your comment "There is a quirk about PSH boards that make them more unstable than others."
What were you referring to? From your experience on these boards, what would you recommend? I'm not going to be able to demo my next board, so I have to make my decision from info that I can find on the internet. I'm 165 pounds, and I'm always paddling in chop, so stability is key for me.
Thanks.
cdnkitesurfer,
The quirk is the rocker. It's a very performance oriented rocker. It feels a bit like a rocking chair. Its more sensitive to where you stand along the length, and offers high performance when you want to use that design factor. When you're slightly on the heavy side for these boards, this quirk becomes more obvious. For lighter surfers, it's probably not a quirk at all.
At your weight, I'd recommend either of those PSH boards. I'd have a hard time recommending Naish with the high prices they ask. Another favorite of mine is the 9'6 C4. It's a gem, but I'm slightly too heavy for it. It does everything well.
Good luck with your choice.
Thanks Dwight
