While there are many pictures of the seastead above water.

Here are a few pictures from down below the seastead.
Below we have the bottom of the spar with fish floating all around. The bottom four posts were put there in case we had a large amount of up and down motion. The plan was to put some steel dampeners to prevent such motion. Fortunately there is virtually zero up and down motion (only a small sidewards movement when the waves hit the spar).
The ear on the side was because the contractor initially thought we were going to attach the anchor lines to the bottom of the spar. The anchor lines were then added to the center of the spar.

Below is a view from the bottom looking up. As you can see, the fish have really taken to hanging out around the seastead. They love it. Previously we would visit the site to do some surveys of various things at that location and we hardly saw any fish out there. Now it like a fish sanctuary. We see dolphins and tuna around our seastead all the time.

We have future plans to create a coral garden growing all along the side of the spar, much like someone may have a garden in their back yard. Using coralcrete we can create an artificial reef that should thrive with sea life. Being stationary we do not need to worry about growth on the “outer hull”. It actually helps with some of the sideward motion due to fluid dynamics.
this is AWESOME! can you please send me more info? I filled out the form but still have not heard back. are the first 20 already sold? how much will they be? what does the interior look like, and is that part customizeable? what does it look like inside the spar? can the shape of the spar be changed? what materials are used to make the topside capsule? thanks again, this is so far the most progress any prototype has made with the deep style as opposed to just floating, that I am aware of, and it is very exciting!
That’s really cool! Inside shots next I hope.
It is a Fish Aggregating Device: https://en.wikipedia.org/wiki/Fish_aggregating_device
Brilliant! I intend to do the same but in a 41 foot Hunter.
