Hey all,

For those of you who have a pulled in shape in your quiver (not a gun but like a supertech/BlurrV2/Acid/Pro/etc) how did you consider the volume. Did you go larger to compensate for less stable shape and more moving water in larger surf? Or smaller for more performance in more critical waves, and because you already have a more stable design to fall back on... or same volume... or maybe you go smaller because you've yet to hit rock bottom and are still dropping volume over time.

I'm not positive I'm gonna pick one up (already traded for one last spring that was too big and sold it)... but I do spend an irrationally amount of time scheming on next board purchase, so I was curious how folks approached volume when adding this type of board. Cheers

If I was to get a pro style I would keep volume at 1.2 or so to get the potential out of the shape and to keep it from having the "log rolling" effect of a small corky board with an unstable outline. Having said that all the brands upsize their pro shape dimension range to something that can handle a little more volume without making the rails too thick if you are the right size.

Thanks, yeah part of me really wants to get a 100L which would be 1.2, maybe just bring both boards every session. A prone surfer who I always see out gets punished learning on a shortboard for like 1h and then swaps to longboard.

Even the performance stock boards at 100L are 28 wide and up, and usually 8ft, this is still a very big board in terms of wave catching and glide compared to a surfer on a shortboard and you have a paddle. I'm guessing if you are like most advancing SUP you can make it work, but will be down to preference and your spot whether it is worth the added effort and falls. Personally I really don't like the nose pulled all the way in for stability catching waves especially in side ribs or chop. Nothing worse than being knocked over right at the point of dropping in.

If you only have one board, it can be an `allarounder' that take on all conditions. But of course it will be a compromise compared to a quiver of specialized ones.
At 6' 85kg I have found that 120l is my minimum. Lucky enough to have built up a quiver but unlike some peoples that have a series of similar boards with small differences, mine is spread out with large differences between.

So my most high performance board is a 8-3x30 119l shortboard shape. Then as follows, 129l larger 9-2x31 shortboard, 9-6x30 138l mini-gun, 10-4x28 140l gun, 10-6x31 149l longboard. I am only at my minimum with one board. I can go big on this one too but it has to be smooth. As the water conditions become more challenging I have a choice of larger boards so I can still be successful in having a fun surf.

Like slsurf, I find that a guild factor of 1.2 is the sweet spot for me.

More and I get the "rolling log effect".

Less and the board becomes noticeably slower to paddle (the board is sunk and displaces a lot of water), plus there is no real "resting" position and I must always actively keep the balance, so I get tired very fast.

But you must also factor in the width:
- a wider board can avoid the "log effect" and allow bigger volumes. E.g. 130L would be too much volume for a 29" board for me, but would be OK for a 31" one.
- wider boards add stability and compensate for the low volume. My 105L 7'3" Gong Fatal at 29"3/4 is as stabler for me as my 120L Gong Alley 8'1" also at 29"3/4, but with a wider plan shape, especially at the nose (2" and 1" more at the one foot offs). But the Alley paddles much faster, so I use it for more than shoulder high conditions, when waves can peak all over the place.

But to answer your original question, I have my "pointy shape" (the Alley) in two sizes: 105L and 120L for my 97kg. 80% of the time I use the 120L, the 105L is for very clean conditions and no crowds, when I know I would have a very high wave count, and would be OK to have a session of at most 1h30 before being too tired. But this is because they are very light (5.8kg with pad for the 120L, 5.2 for the 105L), so the "high volume" 120L is not so cumbersome on the wave because it is so light: you get the volume "for free", basically.

Thanks guys for the really helpful information! The 8x28 Blurr V2 is what was tempting me. On one hand I can picture cranking turns on a nice winter wave, but can also picture trying to get back out before next set comes in and having nose go under, then the awkward 15s dance I do trying to right the ship before getting eventually getting chucked off. I think I'm game for it though:)

having nose go under,


See my trick "Another trick for pointed noses is to keep the tip of the nose well above the water" at www.seabreeze.com.au/forums/Stand-Up-Paddle/Review/An-approximate-way-to-know-the-stability-of-a-sup-board-without-testing-it#2706930

On pointed nose boards, you do not want the nose to ever go under, as then the balance dynamics change radically, and it is hard to manage it. Always Leave a big security margin.

Thanks Colas this is great. Your prior advice on fencing stance has been really useful. cheers

I picked up a 2nd hand smik spitfire V1 8'3" 111 ltr, 29.5" wide, IMO it's a forgiving performance shape. My 8' hipster is fuller in the nose, a different type of board I use for less windy, smaller days as the spitfire is a faster paddler for getting into the wave. Build quality and weight of both smiks are great and they both surf really well. I also have 8.5' 112ltr steller design OZX which I use on bigger windy days as 31" wide and has good stability, it has very sharp rails and is essentially built & shaped like a custom board. I think rail to rail transition is perhaps not as quick on this as on the spitfire due to the width, a bit more footwork required, but on bigger choppy waves that's not quite so important, whereas speed and stability are.

I'm 56 yo, 84 kg 5'11" flotation ratio about 1.32

The Smik Hipster and Spitfire look awesome, wish we could get them in US. The Gongs too. Thanks for sharing info.

I have 2 performance alike boards.I,m 97kg and 188cm tall and only use these boards on holidays because the waves in the netherlands are usually crap.
but when i,m in France, UK, Ireland etc and it is clean my carbon Starboard Pro8.5x29x112l from 2015. Its awesome. That awesomes stops the minute its starts to blow or the water gets a bit confused because then its simply too wobbly.
(Happily expecting a new born Smik Spitfire8.6x126l for that tiny extra bit stability as replacement).

For those hmmmm the forecast looked better days I own a custom: 8.2ft x 30 x110l but with the more fishy wider nose (copied from the starboard Airborne) and a wider tail, taken from the Hypernut with a pro rocker and only 3.7thick with thinned rails.
When paddling only the nose is out, but due the wider nose ad tail its plenty stable in chop/wind/chaos and short period waves that are allover the place ....while still ripping. It givers a bit up to the Pro, but not that much so this holiday (we are now in France) I even left it at home because of a windy forecast.When you are a bit afraid to lose too much stability, a but wider tail or nose adds soo much. Have a look at the Infinity B-line or the Hipster twin that is mentioned as well. They don,t lose out that much performance and have a way bigger useability.

Thanks -this is helpful and sounds like you have a sweet combination of boards. Do you think if you surfed the holiday conditions every week then your 112L Starboard Pro would feel OK in a little chop? That's like 1.15 L/kg for you and I'd go 1.2 with the V2 I was considering. I pick my days and on the break I'd surf this there is some wind blockage and less moving water, but it's rarely truly glassy (according to my surf friend from S. California).

The B-line looks awesome but I think it's a fairly similar outline to my current board (JL Worldwide), but with thinner rails. I would love to try one, but seems like it might replace my current board rather than complement it. cheers

You can get used to everything so yes, but for me for only a couple of days a year I take the easy road. Slightly less tight turning but les tiring and more fun.
Now if I would go to Bali for a month I would grab the pro for sure.
What makes the 2015 pro for me still a very good board is that it has some volume in the nose, making it easier to lean on and balance.
I have tried newer boards and imo they are not really better, just different.

The new Starboard Pro 7'7" is a super intriguing option for an aspirational next board, but I don't think I'd be able to get one this winter and $3k might get me divorced:)

I ordered the 100L V2, friend and I both looking at boards (8x28 New Deal for him), Dave B talked to us both on phone, super nice and helpful. IMO I'd be better off with 109 to surf in near future, but I'm excited to push myself and based on how easy my 110L JLWW is when glassy, I think I could potentially surf 100L V2 OK right now in clean conditions . hopefully work up from there. Wish me luck!
