In the British TV show 'Stingray', who captained the submarine?

Marina.... Aqua Marina....

LaContessa, , Yes, I was always intrigued by the tangled triangle of unrequited love. Troy loved Marina, but she didn't love him. Atlanta Shore loved Troy, but he didn't love her... honestly, as if fighting bad guys in wetsuits with questionable headgear wasn't enough!

JezzerLX, I fondly remember this and The Thunderbirds

British TV very interesting
