Or if you already have the
Gemini, you can forgo the hanging locker and turn the "downstairs" starboard bow compartment of the owner's stateroom into a separate berth by building a berth in the space forward of the ladder up into the stateroom. That would
work well in terms of keeping your youngest close by, and you still have privacy in your actual berth, although you might want at least a curtain if you plan on changing in the standing area forward of the
galley. Most long-term oceanic cruisers don't use their hanging locker space very efficiently anyway: split anything that MUST be hung between the two aft cabin HLs along with whatever the occupant of the aft cabin must hang. You will not need it often, though. And there will be
storage beneath the new berth: you can put drawers in the aft-facing surface of that berth, and put cutout doors in the berth platform to allow access to the storage forward of that, under the mattress. Use a compact fluorescent light so the little one can have light without too much heat (avoids bulb burns, too, since the light for that bunk is likely to be easy to reach).
Hope that all helps: we reconfigured a Prout Snowgoose to an owner-cabin configuration from the extended
salon configuration, and cut back and raised that forward starboard berth, turning it into a large
refrigerator with storage forward. We got the
teak trim from Buck Woods in Marathon, FL. Very reasonable prices and the
teak finished beautifully!
