Well a boat can be super efficient dimension wise for a place to live.
My friends no longer own their world cruiser.
Here's a picture of it...
Millennium Falcon - 60' World Cruiser in Steel ! $275,000 | Spinnaker Sailing
Hmmmmm, I think I have seen that boat before. I am sure there are more than a few boats named Millennium Falcon but not many will have a steel hull. I think I remember this boat because of the name and steel hull. I bet the owners on are the Cruising Forum.
We built our house to be efficient energy and space wise. I designed the house and about the only second guessing I do about the design is our closet space. It would be nice to have added a foot of depth to the closet but that extra space would have cost about $5,500. :shocked:

I made the right design decision but ... :laughing::laughing::laughing:
Looking at boat deck plans has been interesting because so many of those plans waste quite a bit of space and space on a boat is very expensive and precious. People who know us ask how we could move to a boat from a house but we have looked at the space we actually use in our house and we spend most of our time in a few spots in the house. Most obviously, we spend the most time sleeping in bed, :laughing: but our awake time is mostly spent sitting in our assigned seats in the living room. The wifey has her spot and I have mine.

The living room is large to be able to seat company, which we do have frequently, so the room design works and I would not change the room size but looking at the space we actively occupy we could really have a much smaller space. The boat we want has amble seating for 6 people in the "living room" depending on which layout we picked. The reality is that we would both have our assigned seats on the boat just like we have at our current house.
Many people retire, sell the larger home they had when the kids were still living at home, and buy a smaller retirement home. In effect, we are thinking about doing the same thing except the smaller home moves and is a boat.
Both the builder and designer of the boat believe that guest accommodations should be adequate but not too comfortable. You want the guests to come aboard to visit but not stay too long. :shocked::laughing::laughing::laughing: That is a design idea that make sense to me,



and I think it also applies to a house design as well.
