I may have seen an SDI sign at the dive shop at Daniels. Gustele, is that Trunk Divers? Also the dive shop at Marta Kosjie has an SDI sign. These dive shops are both on the road to Westpunt not on a beach. Other than just "seeing" these signs, all the instruction on the island I know is from PADI.
I looked up Trunk Divers and it's PDIC

I think I'm spelling Marta Kosije wrong? They've been in to eat and I never asked for any literature. I can stop next week if you really want her to take the SDI course but it would be much easier to do it at your hotel.
OK The dive center Curacao is at Martha Koosje and has IDD courses.

So, no SDI that I could find.
