From my reading of the two articles, I get the impression that the breakwater is perpendicular to the beach as it "stretches nearly a kilometer into the ocean, has disturbed the natural balance of the eco-system and is washing away the sand from one half of the beach, and depositing it on the other half" and this is exactly what happens when a perpendicular breakwater is built.
The one being proposed by the Negril project is (I recall) parallel to the beach and segmented. That form of design is more conducive to inhibiting sand erosion. There is a study I found that looked at the results of several segmented breakwater designs installed parallel to the shore: https://icce-ojs-tamu.tdl.org/icce/index.php/icce/article/viewFile/4159/3840
For me, it used some unfamiliar vocabulary so I looked it up: tombolos is another word for a sand dune and salients is another word for a bulge in the sand towards the parallel breakwater.
There is already a breakwater parallel to the Negril shore in front of the John Issa house and it seems to be working just fine.
