Is there a way to figure board volume from size measurements?
« on: November 25, 2014, 10:34:15 AM »
Is there a way to get a fairly accurate measurement of volume using the length, thickness and width of your board?  My 7'11 is from a company that is now defunct and my 8'3 is a custom, one-off board, so there is no official volume stats available for either one and I'm curious about the volume of both.  Is there a way to figure approximate volume without any info from the manufacturer?

As I said in the previous thread, You could scan the board and load it into a shaping program which will give a good approximation. You could trace it, draw an inch grid on the tracing, and count square inches, approximating by combining half and quarter grids to get the surface area, then do the same for the sides. You'll get a reasonable number for volume. You could weigh a board with similar construction and known volume and then solve for the proportional volume. You could stack weights on it until it barely sinks, add the weight of the board and solve for volume using 1 gram = 1cc.

Stacking on the weights is the easiest.

Make a tank from ply wood fill with water and measure the water the board displaces when you get two people to submerge. Volume displaced = volume of board

Wow, I totally missed that thread or I would not have even started this one.  My apologies to all.

Fill frac tank with water to top


shove board under water until complete submerged


Measure what spills out.


Use excess water to supply Central California.


Well, you get the idea...

Not really at least accurately.

Volume is just 1 factor in the total equation how a board will perform, especially when it comes to stability and paddling speed. It's an important number but not the only number to consider.

8-4 X 31 1\4.  Round (wide) Diamond Tail Quad Tom Whitaker
 9-4 X 30 1\2. Swallow Stinger Quad Tom Whitaker (ex wifes now)

Wow!  A scientific and detailed process, documented expertly with images of board measuring professionals.  I especially like the image of the submerging technique.
