Experience the Sea of Cortez on the northern Gulf's most popular live-aboard dive board--El Duque! Visit spectacular dive sites like Isla San Pedro Nolasco and swim with friendly, playful California sea lions or witness the awesome sight of a school of scalloped hammerhead sharks. This current washed island is renowned for its clarity and extreme diversity of fish and invertebrate life. The abundance of soft corals makes night diving a must. When you are able to dive these unusually calm waters "El Duque Style," you don't have to rush to get back to the dock. With unlimited air fills, you can let the critters come to you.

We have been diving this area for thirty years and have visited every island in the Sea of Cortez. Whether cruising north to Isla San Pedro Martir or south to Santa Cruz, Animas, or the sea mounts off La Paz, you can always expect the best diving available.

The "Duke" is berthed in the Marina San Carlos, located just 12 kilometers west of Guaymas, Sonora, Mexico. A mere 250 miles south of the Arizona border; the area is easily accessible by automobile on a safe, divided highway. Guaymas/San Carlos also boasts an international airport serviced by Phoenix and Tucson.

The 52' US built Defever trawler is coast guard certified and professionally maintained. Trips are run "Blackbeard Style" with divers sleeping on deck under the star-filled Mexican sky. When necessary, there are bunks for twelve in the sleeping cabins below. Our meals are excellent, and there is always plenty of good healthy food to eat. Two compressors fill new aluminum 80's and a storage system; the air is pure and tested regularly. The boat is equipped with a chase boat and two Ocean Kayaks.
