hi all
i am just vondering what would be a good guide when lloking at a board volume wise, i know i would need something big as i am 6'2 and 120 kg bt i am looking for a rough guide
i currently have a paddleboard that is 11'6 that i paddle but i am unaware of its volume, i have been paddling for a couple of months so i am not a complete beginner but i am just looking for a rough guide as i am looking for a decent allround board
thanks all
At your weight, I'd definitely be steering towards the bigger volume boards like Naish Mana. 9'5 is 190L, and 10'0 x 32" is 210L.

Similar Star-Board SUP's are 10'0 x 34" Whopperhttp://www.star-board-sup.com/2010/products/boards/board_whopper.php
This one is also massive !! 11'2 x 36" and 206L, but probably too similar to what you already have....

Check those out to start with. Check the sizes, try to demo. And see what else is about in those sizes.
New Naish Mana's are coming out, with Bamboo Veneer, so you might get a deal on the previous Mana !! ???
Basic maths says you need about 140L minimum, to float you (120kg), the board and paddle (say 10kg), plus maybe a wet wettie (up to 5kg). But you'll be happier in the 160-220L range.

The volume doesnt always mean stability for a larger person. I am 6ft4 and 110kg and I have trialled the 14 naish and the 14 Bark. The Naish being a larger volume board yet less stable. The reason is us larger persons sink the board more and the larger volume yet narrower board tends to sink more and act like a cork that is top heavy. Go and try out some 10'6 boards which are fish style, slightly wider at 29 to 30 inches but thinner.
The 30 fish style inch board displaces the extra weight and makes the board more user friendly for the surf environment. For the flat water trial trial trial. If your in Sydney dripping wet at Manly and east coast on the sth side have an array of boards to try.
cheers
1.5 x your weight will keep you just comfortable, so 120 x 1.5 = 180 lt's. only as a guide - a lot of other things come in to play ie -ability, balance, type of board width etc
my board, i think, is 100 lt's so the ratio is down to about 1.3, but not much fun in a ne chop.i'm down on comfort, but the surfing part is real good. i mention this just to give you an idea.depends a bit on where and what you are looking to do
cheers
You also need to keep in mind what you want to do with the board. Do you plan on surfing it or just flatwater or a bit of both ? If its surf/allround then fully agree with simondo - a good starting point would be to demo the starboard whopper and naish mana 9.5/10.0. I am only a relative lightweight and have paddled both the boards and they both have masses of float/volume and have awesome reputations for their surfing ability. If you only plan to flatwater paddle then you may need to start looking at boards over 11ft because they will offer much better glide although not necessarily any more stability.
Demo as many boards as you can and now is a good time to be shopping with so many new models arriving in the near future.
Good luck with it.
When you say all round board what do you want it for ? waves, cruisin on the flats
I had a Simon Anderson carrier.. at 10' x 32" it was so stable you could park your car on it.. But it was lot lower in volume than a few of the other brands (157L) so it went really good in the surf.. although i sold it i still think it was by far the best big board i had ridden..It would hold 120kgs no problem at all 
Sweet looking board too
