Aku said 26 litres for a 6’ shorty, floated me to about bottom of rib cage, and a 5’8" fish at 33 litres to about belly button, but those are compsands both weighing about 2.2 and 2.5 kgs with wax 'n fins etc.

Hi. Not sure what you mean? How did I get the volume in litres? When you design the board it gives you an estimate of how many litres/volume.
What I found useful when switching from regular poly boards to compsands was working out how many litres of volume per kilo of board weight (as a proxy for bouyancy - may be totally way off there) for my existing boards, then used that to see how short/thin I could make a compsand and have a similar bouyancy.
So my 4 kilo, 5’10" poly fish with 38 litres of volume could be reduced to 33 litres with a 5’8" 2.5 kilo compsand fish and float me about the same. The compsand catches the waves just as well, even though it’s shorter, planes over flat sections just as well despite being narrower in the tail (16" vs 17"), and is much more responsive being 1/2" thinner (2" thick in the middle - concave deck). Also goes rail to rail much quicker. Also lowered rail volume slightly to adjust for added bouyancy in the rails.
