Welcome to Stanley submarines

About Roatan Institute of Deepsea Exploration

Captain Karl Stanley’s deep diving submarine Idabel , based on the Caribbean island of Roatan, Honduras, is the #1 spot in the world for the last two decades for the public to enter the deepsea.

Idabel will take you deeper into the unexplored Cayman Trench than most people have ever ventured— illuminating depths down to 2,000 feet (610 meters) below the surface. Through the submarine’s large plexiglass viewing bubble you will see a wide variety of deepsea animal life rarely encountered by humans.
Idabel docks at Half Moon Bay in West End, Roatan, in the Bay Islands of Honduras.


Deepsea Submarine Idabel

The vehicle is a one-of-a-kind deep diving submersible designed and custom-built for her exact location on Roatan, Honduras. The sub, which is the first in history constructed of three different sized spheres, is designed to safely transport three people to 3,000 feet (915 meters) below sea level.

The submersible is named “Idabel” in honor of the town in Oklahoma where it was born, and whose inhabitants were more than helpful in the process.
