Swivel in the bulkhead
I was recently in a yacht where hey had mounted an iMac 24 into the bulkhead and could swivel it within the large port between the dining area and the bedroom. While seated at the table you could work on stuff or swivel it around to the bedroom and watch movies while laying down. When not in use it could be lowered into the bulkhead. I thought it was shear genius. The computer could remain very protected from the elements while underway and then when on the hook simply rose up on demand. I'd copy and paste the link but I've been lurking w/out posting for a long time and therefore cannot. I'd love to mimic this one day as it suits our needs as well. Keep in mind the Kauana (our inspiration) cruises over half the year long. Love it!
