I have been riding a borrowed 10' x 29" board ( volume unknown) and going O.K with it so would probably consider myself above a novice with plenty of room for improvement.
i was looking to purchase something a bit more surfable but with a fair degree of stability.
I have been looking at the Starboard 8'10" x 32" wide point.
the volume of this board is 140 litres.
I would put my weight with a fully wet steamer and paddle at about 75Kg's and surfing relatively small surf in all conditions.
A bit of research tells me the volume required in a board for my weight is less than this?
Is there disadvantages to too much volume or would the wide point or similiar do the job for me.
Any assistance,advice or mathematical theories on weight versus volume much aprteciated. appreciated

At your weight mate, the 7.8 wp at 120 litres, is more then enough volume,thats a ratio of 1.6
Of course its not going to track like your 10 footer.But should be stable enough in lumpy conditions. What ever you decide, do it in stages, i wouldn't just yet drop below 1.4 -1.5 ish x (your weight) 75 =105 - 112 litres
which gives you a fair bit of choice.
The Starboard Wide points would be a good choice, also the Fanatic allwaves.
Personally I favour the starboard, nice finer rails for their thickness,surf and turn better on rail.
I have the 9.5 wp as my all rounder its 155 litres, I'm 100+ kg' so its a 1.55 ratio.I can cruise up the river, catch small summer waves easily, steep overhead waves, 15 knt onshore junk and have a ball. If I can only take one board on a trip, this is it.
As far as having to much volume, it all relates to your ability, as you progress and go out in better waves with more speed ,you'l find to much volume makes the board harder to control.
You can't bury the rail in a turn properly it sits up and feels really loose and skatey.

Both my SUPs have more volume than I need but that helps in a lot of ways and the type of waves you surf can play a large part in success on waves. If you live somewhere where the waves have more grunt then you can do better on boards like the wide points but if you are surfing more junk or weaker surf then more volume helps.

It is funny that we all measure our SUPs at times by the volume but there are so many other indicators at play which can determine the best craft for you.

Hi darrylhaddy, I ride a mana 10 ' 210 ltr volume great allrounder for me and kids getting into wave riding now and like you was unsure about volume needed .there are heaps of great brands on market but i was lucky to demo a custom deep 8'6 x 31" 120ltr i was a little unstable at first but for first go from 210 ltr to 120 was very suprised in stability .imo i would go for around this type of volume but nothing to narrow.good luck , demo if can.

I'm 78kg and have a Naish Hokua 9'5".

I'd be wary of going too short and wide as you lose a bit of speed and you'll probably lose some manoeuvrability. I tried the wide point and that's just what I felt.

I should mention I also have a deep 8'11 x 29, which is around 120L but love the Hokua for performance and stability.

The deep is an awesome board but in junky conditions is a bit of a rodeo adventure.

Where are you based? Can you demo some more boards in your area?

Thanks for the assistance/advice guys.
Gives me plenty to consider.
I reckon the key is test driving the things if you can.
I should be able to demo the Allwave and Naish locally.
If only my ability matched my dedication !

The 8.10 WP is a nice board for someone heavier. Even at 90+ kgs I found it to have much more volume, stability and length than I need. It would feel corky and tougher to turn for you for sure. I think many people buy too large a wave SUP early on and outgrow them quickly. Buying something that challenges your balance a bit initially (due to lower volume etc) will likely reward you with better performance on the wave. An athletic friend of mine at 85kgs rides a SB pro 8.0 at 110 L after progressing quickly from a Pocket rocket. Your mileage may vary. It just means you'll get wet a bit more and will have jacked legs and a solid core from the wobbling.

Hi mate, I'm bang on 75kg myself and have been sup'n for a little over a year. My first board was an 8'10 allwave. It was a good second board and helped me progress a lot, but, if I was going to buy another allwave I would go for the 8'6 tho, which came out just after i bought the 8'10 and is probably more suited volume wise. I now own a 2013 8'2 carbon widepoint and I think it's f****** awesome. Stability wise it's almost as comfortable as the allwave, but performance wise it is much better. It's much faster and a lot less corky than the allwave, as well as being way lighter and much more manouvarable. Glide wise i think it's good for a board that is close to 8'0 and once again isnt too far off the 8'10 allwave in this aspect. The allwave wasn't heaps heavy in comparison to other boards, but after a long session and an average walk back to to the car it's weight does get a little tiring. I could probably walk twice the distance or more with the widepoint before I started to feel a bit fatigued. It's also easier to punch through whitewater with and it feels like there is a lot less pull on my legrope when i come off the board and am being dragged in the whitewash. I never thought the construction of the allwave was weak, but i managed to snap it in half in weak two foot drible six months after purchase. Hence the upgrade to the widepoint. I've been riding the widepoint for about 8 weeks now and although I'm very carefull with it due to the paranoia of not wanting to see another board broken, I really do feel this board is quiete bullet proof and I have a lot of confidence in it. All in all I feel that the the carbon 8'2 widepoint is a great board for progession. It is pricey, but if you want to buy a board that probably won't die on you anytime soon and is just a pleasure to use, it's probably one of your best options atm.
