4. Question - Answer
Boat-1 Characterize the choice of landing sites and their evolution over the three years.
Successful landing sites Shifts upwards and downwards from the cone shape area of interdiction as the interdiction in certain area happens more over years.
Boat-2  Characterize the geographical patterns of interdiction over the three years
Moves farther from the Island and covers larger area.
Boat- 3 What is the successful landing rate over the time period?

5. Interdiction sites
Landing sites

6. Pattern
There is also pattern that migrants tried over years to land if got interdicted in past years. That’s interesting pattern. And surprisingly there looks connection b/w type of the boat and their landing pattern.
Ex. Eduardo Catalano, Jesus Vidro interdicted in 2005/06 in Go Fast vessel but landed in 2007 on Rustic vessel type.
