Board volume for weight

I have just been through the process of buying a new board.

Along the cyberway I came across this useful reckoner as to what a board's volume means for stability given your weight (from http://supconnect.mylocallineup.com/SUP-How-tos-Techniques/how-to-understand-volume-on-standup-paddle-boards.html). Here is the snip:



I also read somewhere else that you can adjust the factor for your height - add a kg to your weight for every inch that you are over 5'9". I weigh 88 kgs and am 6'5" high, so my adjusted weight is 95 kgs. I have just bought a 146 litre board, giving a guild factor of 1.5.

I find this a challenge, without being hard work. About right for me, as Goldilocks said.

While these kinds of general calculators make sense it should also be assumed that intelligent board design has been used.

Take for example 2 boards of 10'0 x 30 x 4 1/4 and let's say 145 litres. These boards on paper should be the same but in reality one of them could be much more stable than the other. Oulines, wide point position, rail shape, bottom contour and rocker also play a major part in stability.

Volume is just another measure used in board design and only relative when combined as a function of other more vital dimensions.

I forgot to mention, there is also an adjustment for the moron factor.

Take 2 litres off for every mm your little finger exceeds 28 mm in circumference.

Thanks Marvin, it's a useful guide for buoyancy, which counts depending on skill level as I have found out.

While 2 boards with similar dimensions and the same volume may feel different - pure physics would say that they would both float you equally as well. Not to be confused with stability here it's all shape and volume distribution.
