Interesting interior design concept. Like how you can work on the engine but not crazy about the aft berth being so wide. Guess the lee cloth would go right down the middle but still seems a bit too wide to brace yourself into while on a rolling passage. Having a tight passage berth is so important when one is trying to get some sleep while off watch. If you took out the center table across from the engine box and had a lee cloth there that would be a very good passage berth. And it would be very close to the companionway.
If you look at the 430 test you will see that the tester says briefly (and shows the lock) that you can take away the table between the two settees on the library/tv room and make a sea berth there.
