We study an old variational problem formulated by Euler as Proposition 53 of his Scientia Navalis by means of the direct method of the calculus of variations. Precisely, through relaxation arguments, we prove the existence of minimizers. We fully investigate the analytical structure of the minimizers in dependence of the geometric parameters and we identify the ranges of uniqueness and non-uniqueness.

This paper presents numerical methods to solve optimization problems on the space of convex functions or among convex bodies and gives approximate solutions better than the theoretical known ones, hence demonstrating that the minimizers do not belong to these classes.
