I recently bought a used stock "sliding galley". (Didn’t catch one of the throw aways I keep hearing about). Seems like a good idea to me and I like it. The only problem is the Kenyon 126 stove it came with has been unused for so long all the seals are dry and the tank, pipes etc. look pretty likely to be stopped up with corrosion. I decided to not try to resurrect it after looking for parts and rebuild info. Now I'm using a one burner camp stove but only cook coffee. So I am thinking about simple alcohol burner alternatives that will fit that space and are to my liking. I do have a rail mount grill, only uses charcoal. Another complaint I heard is the ice box doesn't keep ice very long. I am adding spray foam around it from holes drilled in the bottom. But don't expect a miracle; after all it is not designed to be an "ice hole". We like most also use a chest cooler. The water tank is small and just handy for a little rinse water for the coffee cups. But then, I do not expect a 22 ft boat to be a yacht nor do I need a lot of fluff in a boat. I'm a minimalist, and so goes my boat. My Filipina mate is small and comes from an island family that uses outrigger canoes to fish the South China Sea, so she's happy we have a porta potty.
My point is, it’s best to not to bring a suburbia attitude to a sail boat.
In a C22 for real, “Less is more".
