A pod drive installation and hull configurations for mounting a pod drive unit to a hull which includes a horizontally disposed pod drive platform for supporting a rotational pod drive mount for mounting the pod drive unit with a vertically oriented steering axis. The pod drive platform is mounted to the hull, outward of the keel of the vessel, such that the pod drive platform intersects a plane defined by a bottom hull surface tilted from the horizontal along a contour of intersection, between an outboard boundary of the pod drive platform and an inboard boundary of the pod drive platform, and is connected to the bottom hull surface by at least one of an outboard sidewall and an inboard sidewall.
