We are working on a seastead design that will have a 40 by 16 foot living area above the water.
There will be 4 foot wide columns that are about 20 feet long going out from 
from the 4 corners of living area and down into the water at 45 degrees, which half of
each column under water.   The bottoms of the floats will make a rectangle about 44 feet wide and 68 long.
From the bottom of each column there will be 
2 cables going to the adjacent corners to hold it in place.
There will also be a cable making a rectangle between the bottoms of all the floats so we have some
redundancy in case one cable breaks.
The seastead is about 30,000 lbs I think but this is NOT a normal boat hull shape,
it is more like a tiny oil platform as far as drag.

We expect to use 2.5 meter diameter propellers on two submersible mixers and solar power to move
at around 1 MPH plus any help from using eddies.

I live in Anguilla, in the Caribbean.   We will first test the seastead by Anguilla and then
a bit further out in the Caribbean.   I am curious about weather issues for the Seastead.
Clearly we don't want to be around during hurricane season.  So we will probably go to
the southern Caribbean.   

Outside of the hurricane season, if we have weather forecasts and can move 1 MPH, we probably
mostly go on the downwind side of the lesser Antilles islands, it seems we should never
get waves over 15 feet?  And the big waves are basically swells which are not really that bad.

How much storm avoidance can we do at 1 MPH?  Like if we have 3 days notice and can get like 75
miles away, can we avoid the worst of storms usually?

Give me any insight you can about weather related issues for a slow moving seastead in this area.
