Solar Catamaran galley/living space design

Hi
Our plan to build a 45' solar Cat is still on the good way and I start this specific thread to talk about galley design/living space/cockpit (and not solar design).
I create the 3D of the boat so I intent to design the living space in 3D before start to build something.
The current plan is to have the entire area over the bridgedeck for living space and cockpit as the cabines and heads will be in the hulls.

So, what is a good design for a living space roughly 5.4x4m (210x160'')?
At the moment there is a salloon + table on the port side and we plan to keep it.
We expect minimalist furniture and we are not expecting all the refinement and comfort of a typical modern Cat.
K.I.S.S is way more important here than comfort.
Still, we plan induction cookpot, water maker, fridge, freezer and microwave. No dishwasher, oven or other fancy equipment.
There is many opening windows in the front with large fixe windows on each side.
We will probably modify the front center half round build for the mast. This place can be reuse inside.

So, where to start? Where to find inspiration? Material selection?
Good advices are welcome.
Thanks

 

So I continue to think about that and design something rough.
I first thought about putting the sink under the rear starboard window, but quickly realize that if the induction cooktop is in the middle of the ''place'' (name?) that will not be ideal to evacuate cooking steam/fumes.
Now I place the cooktop under the rear starboard window and then I'm thinking about possible consequence if a heavy rain happen and the window is open

I like the large surface countertop and I leave 900mm (35.5'') between cooktop and sink to have place for two peoples.
Then, I take a brake realizing that I forgot to think about a good place for the fridge.
The only thing I'm sure is if we have a front door compact fridge, I don't want this one on the floor. Grabbing stuff at 6'' from the floor is a real pain.

 

For windage, the best design keeps things lower in front, this places design constraints on the front. And then, for natural curves; this means the aft part of the cabin is higher headroom. This creates an opportunity in the aft sections for the best head clearances. For this reason, my shower is aft. I still have room for a shower curtain and no need to duck to enter. Bathroom door is also very high this way and not a ducker.

The forward area real estate is prime offering for windows and seating and seeing outside whether guests or sleeping. And it works well if the headroom is a bit lower.

Of course, one must walk thru the cabin somewhere and so walkways are required as well.

Once you understand the constraints; design around them.

I reread the original post and so no cabin or head.

I would offer a small critique that the interior looks a bit dark, and so if you can add any more windows or light, I would do it now. And, I would probably locate the kitchen rearward to allow for more seating spaces looking outside.

A daybed is also nice, for that moment you want a snooze or to read and fall asleep, or maybe a guest who does not want to use the beds, but wants a 5 minute rest. Can be very helpful as well for anyone waiting for dramamine to kick in!

I would avoid seating facing anything other than windows..

 

Right, everything in the hulls.
Here a rough view of single beds, doubles beds and 2 symmetrical heads.

 

How is everything now?

 

You should start by calculating the maximum weight you can add and the location of the Center of Gravity of the combined weights you add. That will be the constraint.

 

We put it into the water in few months, so then that will give us best idea of weight capacity.
About center of gravity, I have 1200 lbs battery in each hull to play with. A bit more in front, a bit more in rear

 

Here is the complete design who seem good to me.
Not much interesting place on starboard to put the fridge with sink and cooktop, so I simply plan to create a raise platform directly on the side of the rear access door to put the fridge port side.
On the same side a fairly large cabinet for storage and desk surface.
And in the front starboard side, another desk/storage with a 2 place to seat.
So, in blue is places to sit, in light blue can be use for a nap of to sleep 2 people's when table is drop.
Rest of cabinets is storage.

That the rough layout and the next big challenge will be to properly design lightweight and simple cabinets.
Example I have in mind right now is simple frames with plastic containers to store dish set, food, stuff with (or without) curtains to have a better finish.
In short, no doors, no drawers... simple.
Is someone have examples of boat like that?
