At 95kg I'm pretty comfortable on my 110 and 117 (so 1.16 -1.23).

Third man in, five minutes, but there was no fighting!

I was the lightest, shortest, and oldest of the three of us. My King's Accelerator was the other board.

I was surprised at how other boards felt less stable and nervous while paddling. My suspicion is that the King's has a completely flat deck, is not a tri-plane hull variant, and a flatter rocker profile.


My Laser 8'4" with a tri-plane type hull, more rocker, and the spine going through the fins is way less stable. It is wider and has more liters, but not that stable when paddling.

It's clear that there are many contributing factors to stability. YMMV!


We had a lot of fun that day!

But yes, IMO once you find a comfortable "standing volume" (for no better term), than I don't see much additional benefit to any additional volume.

What ratio do you guys think makes for comfortable "standing volume"?  I'm comfortable at 1.23 -- 145 lbs/66 kg on 81 L.   Think there is a sweet spot between 1.0-1.2 for an intermediate?
For "standing volume", I'm thinking 1.10 is about as low as I'm "comfortable" with, and that's kind of pushing it...much below that, and I'm pretty much paddling that whole time.  I'm 93 kg, so that would put 1.10 at 102 L which I'm still OK with able to stand w/o paddling all the time....from there on up it just gets easier, and at about 1.25 (116 L) it becomes stand there talking w/o thinking about it.
Me: 6'1"/200...6'0" Chelu Foil Boards...9'6" Bob Pearson "Laird Noserider"...9'6" Costa Azul Wide Body...14' Lahui Kai "Manta"...8'0" WaveStorm for when proning urges still hit, and 7'3" Chuck Glynn foil board backup.

interesting...so, anonsurfer, imagine your 75L board was the exact same dimensions, but now say, 85L. do you feel like it'd be more stable? less stable? the same?  Seems like, once it floats you, there's not much benefit to the extra volume...right?

My 7-0 x 24 x 75L is very stable so extra volume would not benefit stability.  More volume would give easier paddling and lower performance on wave.   I want performance over ease of paddling so I would not want more volume.   

85L (GF=1.16) would not be bad.  It would be easier to paddle (easy to stand stationary in the line up) but a lot more foam to push around when surfing (less responsive).   I find boards with a lot more volume are corky and harder to balance as they pick up and amplify every bit of chop.   

Everything is a trade off.  Do you want ease of paddling or performance on wave?

Great thread!  Creek & Anon, those test results are really interesting. I'm only 145 lbs (66 kg). Your experiences suggest I could potentially "handle" a board in the 66-70 L range (which seems crazy to me by the numbers).  I'm currently on 81 L (v/w ratio of 1.23) and I really like it's level of float. I'd love to try something in the low/mid 70s to see how it feels.

Everybody is different but you can most likely go lower volume without sacrificing too much balance.   

Try SUPing in some flat shallow water with some extra weight, i.e. 4kg, 8kg, etc.   This will give you an idea of how much volume you can go down.   1kg = 1L.  I bet you can easily add 4-6kg (9-13lb) and have no problem.    I use 4L milk cartons filled with water in a backpack when testing my limits (4L=4kg).

I think the sweet spot is different for each person.  If you have good balance and are a strong paddler a GF of 1.1 is very stable.

I guess a lot is determined by your surf spot. If you are able to get on the wave easily the choice is obvious. When the spot involves a lot of water movement and a hustling crowd I find the low volume results in low wave count. Then having a quiver of different volumes can maintain the stoke level constant.

And special shapes as longboards and guns naturally have “excess” volume due to their specific function. A prone shortboard and longboard have clearly different volumes. Why would the same shapes as a sup be any different?

For sure.  Type of surf, surface conditions, distance to paddle out, ability etc all are factors.

A prone shortboard and longboard have clearly different volumes. Why would the same shapes as a sup be any different?

It's all relative.   A shortboard GF of 0.5 and longboard GF of 1.0 would be considered high.

The volumes and dimensions required for a SUP have inherent limitations.  Adding volume decreases performance.   My goal is to build a SUP with GF=1.0 that performs similar to a prone board with GF = 0.7.   I am getting closer.
