We also have the same layout and vintage.
I am 5 foot 9 and 270.... so... to put this into perspective...
Unlike Saltyhog, my wife and I sleep in two different berths. She gets the large v berth and I get the quarter berth. It works well for us because she doesn't have to listen to my snoring and I am a particularly light sleeper until the sun is about to come up, so any movement wakes me up. Also, its easier for me to pop out to the cockpit
for a look around when I hear something funny
. Which, 99.9% of the time is nothing.
The quarter berth is quite comfy; its a lot larger than it appears when only one is sleeping in it. We put new foam mattresses in and I now sleep about 1000 times better than on our expensive land mattress.
I have slept on the settee and it could stand to be an additional 3 or 4 inches wider, I agree with you on that. For super skinny folks or kids
its just fine.
The table seating is actually quite roomy. As I sit here typing I have a good 6 or 7 inches between me and the table. My wife and I sit next to each other quite easily when we sit for dinner.
