a little help required

They look more aviation-related than yachting related. To me, they're essentially nicer versions on the "tables" you'd find on an airliner when you're in business-class (or the seats facing a bulkhead) and therefore don't have a seat close enough in front of you for your own tray-table.

Perhaps companies that do business-jet interiors could be helpful.

Ditto. This is a fancy version of what you find in 1st class. You'd probably find this version on private jets, but I'd go to an upscale Rv dealer first (probably better price). Look for it on one of their models and see if there is a mfg. tag. It's undoubtedly a chair/table set and I would expect quite costly.

Hi,

Have you been in the fwd cabin recently or does your hatred of crew accom give you a natural leaning to stay aft?

Delta Airbus 1st row 3 weeks ago (my employers treat me well), bells ringing, speakers crackling, lights flashing, a hot towel, bottle of water, a Reese's peanutbutter cup and those trays, except metal and looking like the strongest part of the plane. I'm actually old enough to have vague recolections of when plush seats and full meals were the norm. Extra services were had up in 1st class (coffee, tea or...)
