Captain Ron McCaslin - 21 years and counting! Captain Ron has been captain aboard The Aqua Cat since she was commissioned in 2001 and with us at Blackbeard’s Cruises since 1992. Hot Texas summers led to lifeguarding and later a Scuba Instructor in 1981 while finishing a Chemistry degree at Texas A&M University. Ron holds a 1600 ton license from the US Coast Guard and when not aboard is trying to escape his “honey do list” in Tallahassee, FL, by riding motorcycles, hunting, or woodworking.

He was promoted captain on the Aqua Cat in 2012. After working in the real world and aging behind a computer, he decided to set sail and search for the eternal fountain of youth. His travels took many years and many miles but he finally found the fountain of youth here in the Bahamas and ever since has been getting younger.

First Mate Jason Ward - Jason hails from the state of Texas and graduated from the Lincoln School for Welding.

He eventually worked his way to become the fill in Master on the Blackbeard’s Cruises Fleet and even ran the Cat Ppalu for a bit. When he wasn’t captaining the boats from Miami he was out west skiing and white water rafting. After working here on and off for 24 years there is very little he has not seen. If these waves could talk! He doesn’t do much skiing or white water rafting these days but likes to ride his motor cycle with no particular destination in mind, kind of like sailing where the wind blows him.
