Country Kitchen?

No more galleys on boats and ships?
Or at least a Nautical Kitchen rather than a Country Kitchen

That term has found itself attached to certain Broward listings for whatever reasons ...it denotes a larger than usual galley that includes a family style eating area such as a large booth or farmhouse type kitchen table arraignment and usually an island. Room for the whole family type of deal. That's your country kitchen.

Learning every day, thx.

Actually "Country Kitchen" originated in homes long before Gertrude or others. She may have been the first to apply the term to boats. It's a design layout where the eating area is in the kitchen, not separate. In a home, it brings the dining and the food preparation together, allowing interaction. On a boat with a crew preparing a meal then it would allow interaction between crew and owners/guests.

The term brings memories of large country families where the kitchen was the center of activity and everyone gathered there.

It is by nature a more casual layout. It is more an American concept initially. Another aspect is galley up vs down. This became prevalent in American boats and requested by American buyers of European boats. However, builders were surprised when some European purchasers then also wanted the galley up.

I'll disagree on your definition and have to side with RER.
We saw these early on in the West Coast, usually in the early Raised Pilothouse designs at Westport or Christensen. Had nothing to do with including crew for meals, but was more of an eat in kithchen for less formal meals, or even when formal dining rooms were not designed in.
The best one I saw was the Northcoast yacht Countach, done for a chef. Nordlund had done few and still does them as well.

So give me year when she started the Country Kitchen craze, I am not so sure I buy into the East Coast media bias without some dates. And don't forget Burger was too steps ahead of Broward when it came to RPH yachts.

Yachting out West has always tended to be more casual than out East, with more true owner/operators and less separation between crew/staff and family.

I didn't dispute that, but it was in the housing world long before. I have no idea about the boating world introduction.

Let's see how far back we can go for this country kitchen thing, I'll start with the 1988 Westport 98' RPH M/Y "Golden Delicious", now "Destiny".

I was off on Countach, got it confused with La Corniche, which had a true chef's kitchen design by the talented Bainbridge Islander Tom Henderson, no country kitchen though.

Countach was launched in 1995, had big power DD 16V-149's, I think it had an owner with a fast cruise requirement from the beginning.

Found a 1982 Burger 86' RPH Motoryacht "Serendipty" with the country kitchen design, anything earlier?

It is on yachtworld with drawings as well. I am on my iPad and suck on going back and forth otherwise I would share the link, probably have to ask one of the kids, LOL.
I am sure Broward and Gertrude and Denison were a big impact on popularizing the country kitchen.
The CK is a normal progression of the RPH motoryacht, it got rid of the tight galley kitchen with the dining space forward of the galley bulkhead and opened it up into a better use of space.
Naval Architects like Jack Hargrave (Burger), Ed Monk, Jack Sarin and William Garden had made the natural progression before the name designers became more prominent. You can probably throw in S&S too. I am sure there are earlier vessels as well.
