We are working on a seastead design.

Above the water there will be a big triangle frame.  The
left and right sides will be 70 feet long and the back part of the triangle will be 35 feet wide.
The point opposite the 35 ft side is the front.
The triangle frame will be a truss structure that is 7 feet high (floor to ceiling).
It will be enclosed and the whole inside the living area.  Lots of glass to see out.

There are 3 legs/floats/foils/wings that provide the buoyancy, so it is a bit like a trimaran but with a very soft ride.
Each leg/wing will 19 feet long and have a NACA 0030 foil shape with 10 foot chord and 3 foot width.
Each of the 3 legs will be attached to the underside of the big triangle near one of the 3 points (but the total top of the
leg will be inside the triangle) and going down so that the lower half is in the water.
This makes for a "small waterline area" similar like a small oil platform but one that can move through the water easier because of the foil shape.
The 3 legs will all be parallel with the blunt or "leading edge of the wing" side facing forward so it is low drag for the seastead to move forward.
Each leg will be 50% under the water (so 0.5 * 19 feet) and the top 50% out of the water.
On the top half of the front of each leg, so the top half that is out of the water, will be a built in ladder.

There will be 6 RIM drive thrusters of 1.5 foot diameter, one on each side of the 3 legs/wings about 3 feet up from the bottom.
These RIM drives will have the flat sides toward the front and back of the seastead.

On top of the roof there will be solar all over.

Behind the back near the center will be two supports going out and 2 ropes going down to a dinghy.
The dinghy is a 14 foot RIB boat with an electric Yamaha HARMO outboard.  It is sideways against the center of the backside of the living area.
When the seastead is moving forward the dingy is shielded from the wind by the living area.
Also behind the back on the left and right of the dinghy will be a deck that is 5 feet wide extending beyond the back of the triangle.

There are 3 stabilizers that look like a little airplanes, one attached near the back of each main seastead leg.  
The little airplane has a 12 foot wing-span, 1.5 foot chord, the body 6 feet long, and the elevator has a 2 foot wing-span and 6 inch chord. 
A small actuator makes the elevator angle up or down so it can adjust the angle of 
attack of the main wing of this stabilizer without needing a large actuator.
This is really the "servo tab" idea.
While the thick part of the leg is 3 feet wide the back where the airplane will attach is very thin.  And to get the airplane's
center of lift to balance on the pivot a notch into the front/center of the wing only has to go about 25% of the chord of the wing.

When the seastead is going to be staying in one place for awhile, we can put down 3 helical mooring screws and give the seastead tension legs 
so it becomes nearly stationary when parked.

Two seasteads will be able to connect together with a walkway, one behind the other, so that while underway 
people can move between seasteads, enabling a real community.   





Earlier seastead designs were very slow and I had planned to have the parts made in China but
designed so they all fit in containers.  So parts could be shipped to the Caribbean and the
seastead would be assembled here.

Current seastead designs seem much faster so there are other options worth thinking about.

Having a crew fly to China and then sort of "yacht delivery" to get the seastead back to Anguilla.
This is a long yacht delivery so not too cheap but could work.

Having one captain and some people who want to learn about seasteads.  These could be 
prospective buyers or people just looking for an adventure.  We might charge these people
but we would want to be sure they were going to be helping with some of the work.
This could let us get seasteads without having to put out all the money for a yacht delivery.
There is some risk that this novice crew does something wrong.

Another option is "deck delivery", where the seastead is just put on top of a ship and 
that brings it from China to the Caribbean.

Another option is that the buyers would pick up their seasteads in China.  With this we
could have some sub-options:
     1) We could send one crew member to ride with them and train them on their delivery
     2) We could send one crew member to ride with them and train for a limited time, like 1 month.
     3) We could have video support over Starlink and even the ability to help with
          watches, weather, and navigation, but without any crew member on-board.

We could have a number of different options with different costs and the customer could just pick what they liked.

We could do a “Seastead Convoy”.  After 4–6 seasteads are ready they sail together with 2–3 professional captains 
rotating between vessels. 

If the seasteads have a "convoy mode" where they follow 500 meters behind another seasead automatically,
it may be that a very small crew of say 3 people could deliver 10 boats.

Not all customers will want to go to the Caribbean and we should be willing to help them get wherever they
want to go so we can get the sale.

Can you see other interesting ways to get the seasteads built in China into customer hands?

Please discuss cost estimates for each and the trade-offs and what you think will work in practice.
If customers could choose from the many options, what percentage would end up going for each method?
