Standing on my balcony looking out into the dark ocean at about 11 pm when i saw 3 lights appear in the water about 20 ft from beach.They moved very fast through the water at times disappearing and reappearing in different spot.The water is about 15 ft deep in that area.They appeared to be searching the area.At times it looked like a light beam appeared on top of the water..I took video and pictures and asked hotel about night scuba dives or lights in area,they said no nothing was going on during that time, this occurred 3 more time over my 14 day stay always after 11pm
