Well, it feels corky because it's ... the cork effect :-)

Lateral stability is given by width.

Volume is more complex, with basically two thresholds, and plenty of various side effects:

[1] enough of it not to sink: Some part of the deck is out of the water

[2] enough to have the whole deck out of the water, even at the tail: the less possible drag when paddling, and the bigger "stable spot" lengthwise to stand on it.

are you sure about the 145 L, my Smik is 9-0 x 32 and has 132 L, Rails and part off the deck are wet and my weight is 90 Kilo

The Smik is a mini style loard custom, had some more litres put into it,at times it feels unstable.

I don't know if this will help but I ride the 8'5" x 30.5" 130L JL destroyer as a relatively competent 80Kg 174cm guy and I find it barn door stable, can run around on it almost, I use it on small days/choppy days as a mini-mal type board (around Cottesloe etc) would highly recommend. 2 notes, I do not use the original fins (not enough grip) and I know the blur says it is an all around board but I have had it out down south in bigger surf, chunky head to head and 1/4 high waves, really not fun!! May be OK in a smaller volume but at this size/volume, not a fun experience. I would highly recommend this board though, can paddle and catch waves well is stable hope this helps.

Well, 130/80 means a guild factor of more than 1.6!
This is quite huge, a value more adapted to advanced beginners.

No wonder it feels like a barge and limits you in bigger conditions...

That's what is good about it, it is still very surfable, can turn and carve. Other boards I have ridden in this volume really are barn doors!!!!
