The Mark I PSC Orion's v-berth is laughably short on the port side due to the head location and width. Haven't seen a Mark II yet, but the head is apparently narrower to allow a longer bed.
MKII doesn't have the same head configuration to take up that space. The V is full sized all the way across. Depending on how I feel, sometimes I will sleep long ways across it (sideways?), and I'm 6'0" and fit with extra room.
