Convex Tri
My Andreini does not have any concave.

The bottom is convex to vee.
Convex bottom consisting of a slight Tri Plane with very slight concave in the center blending to Vee then double concave thru the fin .

This bottom was adapted by another- very famous - for his Downrails around 1973 and most top shapers used a variation of this for up to 17 years .
