I like this location not only for the headroom, but because from a structural perspective, the walls create a triple set of transverse bulkheads for hull strength. Crew's quarters are starboard, and the head serves as a day head as well. Privacy is important on any yacht, and designer Dave Martin, who has drawn every Ocean, allowed ample room between the staterooms with a wide companionway. He also made good use of engineroom space. Headroom on centerline is nearly 7' at the back of the compartment tapering downward as you move forward to the bulkhead-mounted dual Racor fuel separators.
Batteries are in fiberglass boxes between the mains.
Wiring is neatly hung in overhead trays. Westerbeke sits abaft the starboard engine. Abaft on centerline is the Cruisair chilled water air-conditioning system. While it is possible to get outboard around the front of the engines, rear access is blocked by exhaust riser hoses and cockpit console inserts. Outboard fuel tanks tighten up things a bit as well, but overall the engineroom appears easy to maintain.
