Please give a baseline distribution of heights and periods for waves in the Caribbean outside of hurricane season.


Next we are looking at a seastead design that can move 30 miles/day. 
The seastead is owned by a family that is working or doing online education via Starlink,
so they are not in any hurry to get any place, but they have decided they 
want to travel clockwise around the Caribbean.  They want to go East just North of Cuba, South just inside the
island chain along the East of the Caribbean, West just North of South America, and North along the edge of central America.
Using Starlink they will have access to modern weather forecast, lets say weather tech is in the year 2028.   
A key part of their plan is to stay out of the main hurricane belt during hurricane season,
so from June 1 to Nov 30 they will be in the "Just North of South America" portion of the loop.

They don't not mind staying in the lee of some island or going into a harbor to avoid high waves.  
They would like to complete the Caribbean loop in about a year but not really a problem if it takes 1.5 years.
Try to estimate if they used the weather forecast and tried to avoid the worst waves what the distribution of waves they faced would be.

What percentage of the time this family be in waves be less than 2.5 meters?  (easy working conditions on this seastead)

How many days per year will this family be waves be over 4.0 meters?  (have to do heavy weather safety precautions, like put out
a sea anchor, if wind is also high, and Mom gets stressed)


As explained above, they plan to be very careful to try to avoid heavy weather.  
The seastead is not rated for hurricanes, so if despite all their attempts to avoid bad weather, what are the chances
of a sudden hurricane forecast, that the slow seastead really would not be able to avoid?

There are 2 emergency "sudden hurricane plans" that I would like you to evaluate:

The first option is to launch a stack of kites that is able to pull the seastead at 3 MPH if wind is over 20 MPH.
The direction is limited to within 30 degrees of downwind.  But if they have 5 days notice this can get
move the seastead much further.

The second option (maybe only used if first option is not sufficient) is leave the seastead on autopilot/remote-via-starlink and 
evacuate all the people in RIB tender and head to shelter.  
They would leave done early in the morning (don't want to be in smaller boat in dark) while the storm was still far away
(do not wait till waves are getting bigger).
The RIB has 2 engines and can take them 200 miles at 15+ MPH (faster if waves low).  

Please How often would you expect they have to use this emergency evacuation plan?   
What are the chances the family does not survive? (not worried about seastead as no humans left onboard)  
How might it fail?

The seastead man-overboard risk is greatly reduced from a family sailing yacht.  
The seastead if far more stable than a sailing yacht, so the risk of falling off is greatly reduced.  
This seastead is only moving 1 MPH will tow a rescue sled 200 feet behind it with a bright red 3/4 inch floating rope.  
In the majority of MOB cases someone can either swim fast enough to catch up to the seastead and climb 
the ladder or get to the rope and go onto the rescue sled.
The sled has a solar powered light so it is easy to find at night and an alarm button that alerts people still on
the seastead.   The person can also pull on the rope hand over hand to pull the sled to the
seastead where there is a ladder.  At 1 MPH how long till the 200 foot behind sled passes the point where the seastead was? 
Every month the family will get together and have one member jump overboard and practice.
They have a strict rule against jumping over unless other people are watching.

Please try to compare the individual risk of to a member of this seastead family dying from a "sudden hurricane" problem 
or MOB problem to that of a member of a normal family sailing yacht dying from bad weather or MOB death.
