March 2024 in Puerto Juárez (Cancun) between Isla Mujeres and Costa Mujeres, we observed a USO travel from our left to our far right. Check our video separate video post on UAP Task Force here.
This under sea object (USO) had no Port, Starboard or Stern lights. No navigation lights at all, No engine sounds and no wake. Obviously dangerous and illegal for an under sea vessel or boat to be traveling without some form of running lights above water in that area so it’s more likely something else.
There were other boats further out that had running lights running in the opposite direction toward Isle Mujeres from Puerto Juárez (Cancun) [red] but the USO was between Isla Mujeres but closer to shore; Path shown with in yellow.
We were near Costa Mujeres, and observed the USO travel from our left to our far right in just a few minutes, completely underwater. This is a high rate of speed, probably 40-50 Knots so not possible for a manned submersible and even difficult for a boat on the surface.
We shined a 5 W LED flashlight toward the object, but there was no vessel above the water, just a USO light underwater. That was not what we expected.
We were there for several nights, yet this one-time sighting was the only time we witnessed this activity.
We did further research and cannot find any tour group operating and under sea vessel in that area.
The Cancun Underwater Museum of Art (MUSA) a uses a large glass-bottom boat boat (28’) with full navigation lights and even additional lighting around the deck. On the map below, you can see the location of that underwater MUSA tour area. This is not where we saw the USO, nor would explain the observed path of travel of our observed USO ,
