So many good comments, info and experiences. I will not do it one by one, it would take too long.
Many say that it is better to have separate shower in the head, why? In my case, it is not separate. I presume that it is about saving time because two people can do two "tasks" at the same time, especially if one task is "emergency task" or is it something else?
Having a place to escape is a plus, definitely and I believe that one was from Ski, very motivating comment! And yes, not bringing all the stuff and not thinking yet of throwing away stuff. But, I am curious, what are the stuff that pile up in time when you are liveaboard, many of you stating that as main problem? I mean, you probably do think of it before bringing it compared to house living. We did piling up of food and clothes when traveling for 3 weeks, but we had enough "places", the hardest task was to arrange it properly in the available space, but if you arrange it in a good way, actually there is still a lot of room. Yes, you choose some food a bit differently, too. This boat actually has a lot of space for storage, which you become aware of when you need it. Since I have rearranged the boat during restoration/renovation process, I also have big storage instead of two original 300 liter gasoline fuel tanks. I have redesigned central tank which was for water to be for 220 liters of diesel fuel (more than enough, if needed more, a couple of plastic jerrycans do the job). And the water tank is now flexible tank under the V-berth, which also counteracts the weight of that one big diesel which is now in the stern instead of two light gasoline engines. Too many technical details for this thread...Well, some of you said that washing and drying machine are valuable, in those storage where tanks were, I could integrate smallest such household machines if that turns up to be the problem, but I would prefer not to do it in the beginning.
Someone said nice vacation and weekend boat, thanks, that one I can already confirm. Vacation boat in remote place would be a second option currently.
I agree that it is about the type of person(s) at most.
I need to process all of it now for some time and start acting.
