We are searching for a seastead design that works as a minimal viable product for a single family,
maybe a couple, maybe a couple with 1 to 4 children.  The first product might only be ok for the smaller family size.


We want to be able to circle the Caribbean.  If we go East just North of Cuba, then South just West of the island
chain, then West just North of South America (staying in this area the full hurricane season), then
North along the East side of central America the currents and winds are not too bad.

We want to be totally solar powered.   So designs with lots of space for solar are good.

If we can move at 1 to 3 MPH it is probably fast enough to stay in control on such a route.

For Normal Caribbean waves, say 3 to 5 feet and 3 to 5 seconds, we want a seastead design that moves very gently so
that someone could keep working on a computer, or cooking, or whatever without trouble.

Sometimes swells from distant storms can get to 15 feet and a normal boat just rides over these.
These can be longer period waves, like 15 seconds.  
We want a seastead design that rides up over this type of wave, acting somewhat like a boat for long period waves.
We do not want to slam into the wave.  
This is rare enough that it is ok if the residents are not able to continue working on their computers
when waves are this high.

We would like designs that are much cheaper than a traditional family yacht of similar living space.

We live in the Caribbean and expect this to be the first market.  We hope for designs that 
where the key parts could be fabricated in someplace like China where costs are low
and shipped in regular 40 foot containers (the fewer the better) with assembly not taking too much skill or time.

And we want very safe designs.  This is new an so things have a higher chance of going wrong.
We need to have redundancy and reliability built into the design.

What design can you come up with that best fits the above?
