103lt should, but depends how board was measured in first place because volume should take into account weight of board.
manufacturers can do some odd things though
Apparently not. ( Takes into account of the actual board weight ).
These days when they design a board it is the volume of the foam alone. This is done as companies often offer various construction methods, therefore they have the one shape that comes in at different weights. Thats according to lots of shapers.
Volume also doesn't take into account for width, distribution etc so a wide board will support more weight but can have the same volume as a narrower board.
In the old days they used to actually put them in a tank with weights on them and see when it started to sink.
Sometimes too, like Mark said, they often talk volume down so the sailor things that his 88 litre board can hold a bigger sail and then think what a great board it is when its actually a 90 litre board.
The 107 in theory should be more floaty as theres only 1.4kg difference in weight but 4 litres difference, they are both the same width, also would depend on where the volume is placed within the boards, one may have a really thick tail etc. Also the extra length should in theory create more glide but that also depends on rocker, fin placement, Nast track position, the list is endless.
Best to just go out and sail them and see which one works best for you.
