Chancho: 7’6 x 22” x 2 7/8” 56.0 ltr
Big Boy: 7’6 x 23” x 3” 57.5 ltr
So even though the latter is wider, thicker, and has more volume, you think it'll be (1) less stable, (2) easier to go rail to rail, and (3) faster? Is the narrower nose that significant?
(This is purely for me to learn more about boards. I'd love to get on a faster & more fun board.)
So remember that these measurements are the maximum points of the board. So while length, of course, is directly comparable, width and thickness are not, because of the outline (shape of the board) and foil (how the foam/thickness is distributed on the surfboard)
If you look at the two boards, the Chancho has much straighter rails. If you took a point, say, 18 inches from the nose and tail, its probably still 19 inches wide. Whereas the Bigboy, it may only be 15 inches wide at that point. Those figures might be wrong, but in any case there is a significant difference, keeping in mind that 1 inch is a lot on a surfboard. So while the Chancho at its maximum width is narrower, its overall surface area is a lot greater because it stays wide for most of the board. Whereas the BigBoy has a curved outline and narrows fairly quickly from its wide point
Similarly the thickness will differ - in this case the boards arent too different ie they are thick in the middle and hold their thickness for a lot of the board, narrowing at the nose and tail. But it does look like the Big Boy has slightly narrower rails (edges) ie the difference in thickness from the middle (thickest point) to the edge is more than the difference for the Chancho.
The bigBoy also has quite a bit more rocker than the Chancho.
More curved outlines, thinner nose and rails/increased foil rate and (to some extent) more nose rocker all work to provide easier turning (as in, a tighter turning radius); but turning is the converse of stability ie more stable, harder to turn. Straight rails, wider nose and tail all increase stability.

Why longboards can shoot down the line, but need a lot of space and time to do big turns
Of course there are many other elements involved - bottom contours, rail design etc etc. For example, the Chancho's wide point is further forward than the BigBoys, which improves paddling (and probably stability for most surfers) but again increases the turning arc.
hope that helps. Boards are a never ending complexity of interrelationships, all of which trade off something good for something less good
