Cache is not at the posted coordinates, solve this puzzle first!
Hi! I'm the guy on the boat. My name is Cannon Man Ralph. I'm in charge of the cannons aboard Captain Luke's ship, 'The Shark Bite'. I'm one of the younger crew members and I am sometimes teased for my funny way of talking. I would be really happy for you to come find this cache! (Captain Luke might want you to do his cache first... -GCADQCK- you know, being the captain and all. But he doesn't have to know...) People tell me that I'm impulsive, the usual examples that they point out are the time that I wanted to capture a row boat that only had a guy and his lunch in it, and the time that I purchased a barrel full of cookies. And the last and most essential thing you must know,
I LOVE CANNONS!!!!
